OLAW welcomes comments on any of its policy guidance, click here for more information.
OLAW develops and monitors, as well as exercises compliance oversight relative to the Public Health Service Policy on Humane Care and Use of Laboratory Animals (the "PHS Policy"). One of OLAW's primary functions is to advise awarding units and awardee institutions concerning the implementation of the PHS Policy. OLAW often provides this advice by responding to policy-related questions submitted by such units and institutions. The following FAQs provide guidance that represents OLAW's current thinking on these topics. This guidance is based on OLAW's experience with the subject matter and draws on best practices followed by the biomedical community regarding the use of research animals. Unless specific statutory or regulatory requirements are cited, the FAQs should be viewed as recommendations in that an institution may use an alternative approach if the approach satisfies the requirements of the PHS Policy.
The USDA Animal and Plant Health Inspection Service (APHIS), Animal Care has reviewed and concurs with the guidance provided in these FAQs where applicable.
Should institutions apply the PHS Policy to all animal activities regardless of the source of funding?There are many valid reasons for institutions to perform program oversight institution-wide using uniform and consistent standards for animal care and use. Likewise, it is generally impractical to separate activities based on the source of funding. Institutions must implement the PHS Policy for all PHS supported activities involving animals, and must ensure that any standards that might not be consistent with PHS Policy do not affect or pose risks to PHS supported activities.
It is permissible for institutions to delineate animal areas that are programmatically and functionally separate and that do not support PHS animal activities such as a herd of beef cattle used for food production or a stable of riding horses. The Assurance should explicitly reflect the exclusion of any specific area or activity. [A1, A4]
Does the PHS Policy apply to the production of custom antibodies or to the purchase of surgically modified animals?
The generation of custom antibodies is an activity involving vertebrate animals and covered by PHS Policy. Antibodies are considered customized if produced using antigen(s) provided by or at the request of the investigator (i.e., not purchased off-the-shelf). An organization producing custom antibodies for an awardee must have or obtain an Assurance, or be included as a component of the awardee’s Assurance. In addition, the awardee must provide verification of project-specific IACUC approval for the production of the antibodies.Similar guidance applies to surgical procedures. Surgery conducted in response to a specific, custom request is covered by the PHS Policy. An organization conducting custom surgery for an awardee must have or obtain an Assurance, or be included as a component of the awardee’s Assurance. In addition, the awardee must provide verification of project-specific IACUC approval for conducting the surgery. When both organizations hold Assurances, some latitude is allowed in determining which IACUC will review the proposal. However, the awardee always retains primary responsibility for ensuring compliance with PHS Policy. [D6, A11]
The use of dead animals or parts of animals is not covered by the PHS Policy unless the activity involves (1) killing animals for the purpose of obtaining or using their tissues or other materials, or (2) project-specific antemortem manipulation of animals prior to killing them. If either circumstance is applicable to the acquisition of dead animals, body parts or tissues, prior IACUC protocol review and approval are required.
Although avian and other egg-laying vertebrate species develop backbones prior to hatching, OLAW interprets the PHS Policy as applicable to their offspring only after hatching. The egg-laying adult animal is covered by the Policy. OLAW expects Assured institutions to have policies and procedures in place that address the care or euthanasia of animals that hatch unexpectedly.
The IACUC is responsible for oversight of vertebrate animal activities supported by the PHS and those supported by NSF and VA in accord with PHS Policy. To conduct such activities in the field, the investigator must provide the IACUC with the following information:
- where the activity will be conducted;
- what procedures will be involved;
- a brief description of how those procedures are likely to affect the biology and ecology of the study animals by describing the relationship of that species to the habitat and to other species found in the study area (including the nature and duration of potential effects); and
- assurance that permit requirements of pertinent local, state, national, and international wildlife regulations will be obtained before work begins.
If the IACUC determines that the proposed activity is likely to alter or influence the activity of the study animals or other species found in the study area, then protocol review and approval is required. However, if the IACUC determines that the proposed activity will not alter or influence the activity of the study animals, IACUC review and approval is not needed.
Investigators are encouraged to consult relevant professional societies, available guidelines, wildlife biologists, and veterinarians, as applicable, in the design of the field studies (Guide page 32, Appendix A). Studies with the potential to impact the health or safety of personnel (Guide page 18) or the animal’s environment may need IACUC oversight, even if described as purely observational or behavioral. When capture, handling, confinement, transportation, anesthesia, euthanasia, or invasive procedures are involved, the IACUC must ensure that proposed studies are in accord with the Guide (page 32). A study on free-living wild USDA-covered species that involves invasive procedures, harms or materially alters the behavior of an animal under study is covered by USDA animal welfare regulations and requires IACUC review and approval.FAQ E4: Is the IACUC required to inspect field study sites?
The PHS Policy (PHS Policy I.) covers live vertebrate animals used or intended for use in research, research training, and biological testing activities conducted or supported by the PHS. The PHS Policy and the Animal Welfare Act and Regulations (AWAR) do not distinguish between animals owned by the institution and privately owned animals. Pets used in research must be covered under an IACUC-approved protocol. The institution must have an OLAW-approved Animal Welfare Assurance covering all performance sites. The institution should ensure that the informed consent of the owner is obtained prior to the conduct of the research. The institution may want to involve their legal counsel in the development of informed consent documents.
How can the IACUC determine if activities involving privately owned animals constitute veterinary clinical care or research activities?When a privately owned animal is recruited, with the owner’s consent, for participation in a research study or veterinary clinical trial and the activity includes collection or generation of data for research purposes, such activities are considered research and are subject to IACUC oversight.
Veterinary research activities are typically supported by a grant or contract. The data are collected for the advancement of animal and/or human health. If the study is PHS funded, the institution must have an OLAW-approved Animal Welfare Assurance covering all performance sites and IACUC approval for the research activity. If the study is being conducted in collaboration with a private clinical veterinary practice, the operational components of the practice associated with the research activity should be a covered component of an Assured institution.
When doing research on a pet, the institution is responsible for obtaining informed consent for the research activity. If the research activity is being conducted in collaboration with a private veterinary practice, the institution should consider the use of a memorandum of understanding agreement. The institutional legal counsel may be involved in the development of the document.
The veterinary clinical care of a privately owned animal is not a research activity and does not require IACUC approval. Veterinary clinical care is typically offered as a fee-for-service activity and is regulated by state veterinary licensing boards.
The IACUC must consist of at least 5 members who are appointed by the institution's chief executive officer (CEO). If the CEO delegates appointment authority, the delegation must be specific and in writing.The appointed members must be qualified through experience and expertise to provide oversight for the institution's animal programs, facilities, and procedures. At a minimum the IACUC must include a veterinarian, a practicing scientist experienced in animal research, a person whose primary concerns are in a nonscientific area, and a person who is unaffiliated with the institution except as a member of the IACUC (sometimes referred to as a public member). An individual who qualifies to fill more than one of the specified categories may be appointed to do so, but the committee must still consist of at least 5 members. The unaffiliated member should have no discernible ties or ongoing affiliation with the institution, and may not be a member of the immediate family of a person who is affiliated with the institution. Immediate family includes parent, spouse, child and sibling. Appointment of an individual who is unambiguously unaffiliated is the best way to fulfill the letter and spirit of this provision. PHS Policy incorporates the Guide which specifies that public members should not be laboratory animal users (Guide page 24). The veterinarian on the IACUC must have direct or delegated program authority and responsibility for animal-related activities and therefore is always considered to be affiliated with the institution.
If an appointed member who fulfills one of the required specified positions (i.e., scientist, nonscientist, veterinarian, or unaffiliated) leaves the committee so that that position is no longer filled, the IACUC is not properly constituted and may not conduct official business until a member who fulfills the required position is appointed by the CEO (or designee).
Provisions for appointing alternate members are addressed in the NIH Guide for Grants and Contracts NOT-OD-11-053.
NOT-OD-11-053 does not preclude designation of one alternate for multiple regular members, provided the alternate for a member fulfilling a specific membership requirement (e.g., nonscientist) also fulfills that requirement. An alternate may not represent more than one member at any one time. Conversely, it is permissible to appoint more than one alternate to represent a particular member, but again, if the member fulfills a specific membership requirement then the alternate must also fulfill that requirement.
The presence of any one specific member is not necessary in order to conduct official business or to meet the quorum requirement. [A1]
Attention should be paid to attendance at IACUC meetings to ensure that an appropriate mix of members attends meetings. Chronic nonattendance by IACUC members, especially those explicitly required by PHS Policy or USDA regulations, implies a lack of participation in the oversight responsibilities of the IACUC. [A1]
A quorum is a majority of the total number of voting members of the IACUC. For example, to achieve a quorum in an IACUC with 20 committee members, at least 11 members must participate. A majority vote of the quorum present at a convened meeting is required for the IACUC to:
- conduct full committee review and approval of a proposed project or of a significant change to a project, and
- suspend an activity.
Members may not participate in the review or approval of a project(s) in which they have a conflict of interest, except to provide information. Recused members also may not contribute to the quorum for the vote on that specific project. Abstentions from voting due to a conflict of interest:
- do not alter the total quorum requirements, and
- do not change the number of votes required to conduct business at a meeting of the convened quorum as described in 1 and 2 above.
For a vote to be valid, a quorum (>50% of the total IACUC voting members) must be maintained. If a member recusal reduces the number of IACUC members qualified to vote, for example, if the minimum number of eligible voting members present changes from 11 to 10, then the IACUC may not vote on that specific project. IACUCs must ensure that the required number of voting members present are able to meet the minimum quorum requirements by considering alternate member(s) (see NOT-OD-11-053 and FAQ B.2.) and/or telecommunications (see NOT-OD-06-052). If a recusal results in the loss of a quorum, the business associated with the conflict of interest must be tabled until a quorum is present.
Institutions have discretion to subject animal activities to IACUC oversight regardless of the source of funding. This practice ensures uniform standards, appropriate oversight and accountability, and therefore is often in the best interest of the institution. (See also FAQ A1).
USDA requires IACUC oversight of any covered animal activity where (1) the animal has been acquired or transported by the facility, or (2) the research is being supported by any Federal funding source.
PHS Policy requires that minutes of IACUC meetings, records of attendance, activities of the Committee, and Committee deliberations, be maintained by the institution. Accordingly there should be documentation of major issues discussed by the IACUC and the outcome of the discussions in sufficient detail for an outsider to ascertain the nature of the discussion and the conclusions reached. Written transcripts or tape recordings of meetings are not required.
Provisions for conducting convened meetings via tele- or videoconferencing are addressed in the NIH Guide for Grants and Contracts NOT-OD-06-052.
Yes. The PHS Policy, Guide, and the USDA Animal Welfare Regulations presume that all ongoing animal activities have received the required prospective review and approval. An activity that has been undertaken without prior approval should be halted and subsequently reported to OLAW because it constitutes serious noncompliance.
Does the Institutional Official have authority to halt an activity that was previously approved by the IACUC, or to approve one that was not initially approved by the IACUC?The Institutional Official (or another authorized official) may unilaterally halt, terminate, or impose sanctions on any animal activity, as this is not prohibited by the PHS Policy. However, the Institutional Official (or another authorized official) may not approve or reinstate any animal activity without IACUC approval. (PHS Policy IV.C.8)
Nominal compensation for service on the IACUC, or reimbursement for expenses such as parking and travel costs, is generally not viewed as jeopardizing the nonaffiliated status of a member. Any compensation for participation should not be so substantial as to influence voting or reflect an important source of income. It is acceptable for the institution pay for IACUC training of nonaffiliated members (e.g., attendance at IACUC 101). [A1]
The PHS Policy IV.A.3.b.(3) describes the nonscientific member as one member whose primary concerns are in a nonscientific area (for example, ethicist, lawyer, member of the clergy). The intent of the Policy is to have a diversity of perspectives in the membership of the committee and have an individual with a naïve attitude with regard to science and scientific activities. A person without scientific training meets the intent of the Policy, such as an ethicist, lawyer, or member of the clergy, as the Policy gives as examples. Some other examples include librarians, those working in business or finance, or instructors in English, history, or other liberal arts disciplines. When the rationale for categorizing an individual as a nonscientist is not apparent based on their occupation or training, the institution should maintain written documentation of the reason for the categorization. (See NOT-OD-15-109)
Does OLAW expect the IACUC to notify NIH when there is a change in an animal activity supported by PHS funds?The terms “significant change” and “change in scope” have different meanings. According to NIH Grants Policy Statement (NIH GPS, chapter 188.8.131.52), change in scope refers to a change in the direction, type of research or training from the aims, objectives, or purposes of the approved project. A change in an animal activity can be both a significant change requiring IACUC review and a change in scope requiring notification to the NIH funding component. However, a significant change is not necessarily a change in scope.
For guidance regarding significant changes that require IACUC approval see NOT-OD-14-126. As described in the PHS Policy IV.B.7, the IACUC is responsible for reviewing significant changes and approving, requiring modifications (to secure approval), or disapproving the proposed change. The IACUC is not required to notify OLAW or the NIH funding component of this type of change. However, conducting procedures that constitute a significant change in approved animal activities without prior IACUC approval is serious noncompliance that must be reported to OLAW. Additional information may be found at FAQ B9 of IACUC Composition, Functions and Authority and Notice NOT-OD-05-034.
Prior approval of a change in the scope of the research is required by GPS, which provides examples of potential indicators of changes in scope. These examples are not intended to imply that any change in animal model or in approved use of animals always represents a change in scope.
The IACUC is not responsible for notifying the NIH of changes in scope; rather the Principal Investigator (PI) and the Authorized Organizational Official (AOO) are responsible for requesting approval of a change in scope. The request for a change in scope must be made in writing to the Grants Management Officer (GMO) of the NIH Institute or Center (IC) that funds the grant (the funding component). The request must be made no less than 30 days before the proposed change and must be signed by both the PI and the AOO.
The PHS Policy IV.A.3.b.(4) describes the nonaffiliated member as “one individual who is not affiliated with the institution in any way other than as a member of the IACUC, and is not a member of the immediate family of a person who is affiliated with the institution.” The nonaffiliated member represents the general community interests in the proper care and use of animals. The nonaffiliated member is (1) not a laboratory animal user or former user, (2) not affiliated with the institution, or (3) not an immediate family member of an individual affiliated with the institution. Immediate family includes parent, spouse, child, and sibling.
In evaluating the qualifications of an individual to serve as a nonaffiliated member, the Chief Executive Officer should confirm the appointee has no discernible ties or ongoing affiliation with the institution. Regarding service of former employees or students as nonaffiliated members, the appointing official must be assured that the person is not in any way obligated to the institution. Real or perceived conflicts of interest must be avoided to ensure the IACUC’s and the institution’s integrity. Appointment of an individual who is unambiguously unaffiliated is the most effective way to fulfill the intent of the Policy. Public member is another term for nonaffiliated member. (See NOT-OD-15-109)
Yes, as long as that individual meets the requirements for each position. The PHS Policy states, “An individual who meets the requirements of more than one of the categories detailed in IV.A.3.b.(1)-(4) of this Policy may fulfill more than one requirement. However, no committee may consist of fewer than five members.” (See NOT-OD-15-109)
The annual report is a document prepared by the IACUC and submitted to OLAW through the Institutional Official. It describes any changes in the institution’s program of animal care and use, AAALAC accreditation status, changes of Institutional Official and in IACUC membership, the dates that the IACUC conducted its semiannual evaluations of the program and facilities, and any minority views.
Descriptions of program changes should be comprehensive and in sufficient detail to replace information in the currently approved Assurance. If there are no changes, then a statement to that effect must be provided. Annual Reports must represent the consensus of the Committee and include any minority views filed by members of the IACUC.
In the year 2020, the report will cover a partial year (January 1 – September 30, 2020), with the report due to OLAW by December 1, 2020 (but no earlier than September 30, 2020).
Beginning in 2021, the reporting period for the Annual Report to OLAW will be harmonized with the reporting period for the Annual Report to USDA to occur over the fiscal year (October 1 – September 30). Therefore, in 2021 and beyond, the Annual Report to OLAW will be due by December 1st (but no earlier than September 30) for the previous fiscal year.
To learn more and for a sample annual report, see the Annual Report to OLAW.
What kinds of situations should be reported to OLAW under IV.F.3. of the PHS Policy, and when, where, and how should they be reported?Guidance on reporting noncompliance is in the NIH Guide for Grants and Contracts NOT-OD-05-034.
The Freedom of Information Act (FOIA), 5 U.S.C.522, provides individuals with a right of access to records in the possession of the federal government. All documents submitted to OLAW are subject to the FOIA. However, the government may withhold information pursuant to the exemptions and exclusions contained in FOIA. To learn more about the NIH FOIA process, see the OLAW Online Seminar: Openness and Transparency and Biomedical Research Oversight.
In a ruling by the US District Court for the District of Columbia Div. No 99-3024, In Defense of Animals v. Department of Health and Human Services (HHS), 9/28/2001, the Court ruled that HHS (NIH’s parent organization) may withhold IACUC members’ names. NIH does release the names of the IACUC Chairperson, veterinarian, and Institutional Official as reported in Assurances.
Note also that footnote 6 in the PHS Policy allows institutions to represent the name of IACUC members other than the chair and veterinarian by using numbers or other symbols, provided there is sufficient information to allow OLAW to determine that appointees are appropriately qualified. Identities of members must be readily ascertainable by the institution and available to OLAW upon request.
In providing the facility and species inventory as part of the Assurance submitted to OLAW, institutions may identify animal areas in any manner, e.g., initials, ID number. It is not necessary to provide OLAW with detailed diagrams of facilities or room numbers, unless specifically requested by OLAW.
Institutions are also advised to consult the Guidance on Prompt Reporting to OLAW under the PHS Policy (NIH Guide for Grants and Contracts NOT-OD-05-034) with respect to what information is expected to be reported when reporting noncompliance. Disciplinary documents (e.g., letters of reprimand) and correspondence between the IACUC and investigators are generally not required by OLAW, although they may be requested.
Additional information about the FOIA, including guidelines for submitting FOIA requests, is available at: http://www.nih.gov/icd/od/foia/index.htm
Are institutions required by FOIA to release information about their research, animal care programs, and IACUCs?The Freedom of Information Act (FOIA) is a federal law that provides individuals with a right of access to records in the possession or control of the federal government. That means that OLAW is required to release information in its possession or control unless that information is specifically exempted from release as described in section 522(b) of the FOIA. There is no federal requirement for institutions (other than the federal government) to comply with the federal FOIA. State or local laws, sometimes referred to as “Sunshine Laws” may govern the release of information by institutions. These vary widely from state to state. Even within a state, different regulations may govern disclosure for public and private institutions. Institutions are encouraged to seek the advice of their legal counsel regarding disclosure of information.
Institutions must maintain records of minority views expressed (1) as recommendations to the Institutional Official and/or (2) during semiannual inspections. These minority views must be included in the Annual Report to OLAW. PHS requirements for recording and reporting minority views are described in the PHS Policy at IV.E.1.d. OLAW provides a sample annual report document that institutions may find useful.
Some IACUCs have expressed confusion about the difference between a minority view and a dissenting vote.
- Both protocol approval and suspension of animal study protocols by the IACUC require a majority vote of a quorum of the IACUC. Although an IACUC member’s dissenting vote on these issues must be recorded in the minutes, this does not constitute a minority view for reporting purposes.
- Any IACUC member may submit a minority view to OLAW addressing any aspect of the institution’s animal program, facilities, or personnel training. Whether OLAW receives a minority view as part of an annual report, renewal Assurance document materials, or directly from the dissenting IACUC member, it carefully reviews the information provided in accordance with requirements of the PHS Policy and provisions of the Guide.
The IACUC must review and approve departures from the Guide. IACUC approval of departures from the Guide must be based on scientific, veterinary medical, or animal welfare issues. Semiannual reports from the IACUC to the Institutional Official (IO) must identify specifically any departures from the Guide. (PHS Policy IV.B.3) Read the Guide carefully; it establishes exceptions in specific situations; these are not departures from the Guide and are not required to be reported to the IO.Guidance in the Eighth Edition of the Guide is stated in terms of standards that must be met, standards that should be met and standards that may be met.
OLAW defines must as a minimum standard required of all Assured institutions. Deviation from these standards with IACUC approval is a departure from the Guide and must be reported in the semiannual report. Deviation from a must statement without IACUC approval is a noncompliance that must be reported to OLAW through the IO.
Reporting requirements for should statements in the Guide vary. Should statements often involve performance standards. Well-established performance standards are not departures from the Guide and need not be reported in the semiannual report to the IO. Deviation from a should statement with IACUC approval is a departure from the Guide and must be reported in the semiannual report to the IO. Deviation from a should statement without IACUC approval is a noncompliance that must be reported to OLAW through the IO.
May statements in the Guide are suggestions that institutions can choose to implement if suitable for their program and deviations are not included in the semiannual report to the IO.
For examples of reporting requirements in varying circumstances and additional information, see Departures from the Guide.
Under PHS Policy the maximum interval between IACUC review and approval is three years, i.e., a complete de novo review is required at least every three years. The review must encompass all of the criteria in the Policy at IV.C.1.a.-g.
There are only two valid methods of IACUC review allowed by the PHS Policy: (1) full-committee review by a convened quorum of the members of the IACUC, or (2) designated member review by one or more members, employed only after all voting members have been provided an opportunity to call for full-committee review.
Full IACUC review may result in approval, a requirement for modifications (to secure approval), or withholding of approval. Full committee review must occur during a convened meeting of a quorum of the IACUC members, and with a formal vote. It is insufficient to poll each member individually in lieu of a convened quorum when using the full committee method of review. See NIH Guide for Grants and Contracts NOT-OD-06-052 regarding use of tele- or videoconferencing when a convened meeting is required.
Designated member review may be utilized only after all members have been provided the opportunity to call for full-committee review. If any member requests full committee review then that method must be used. If not, the IACUC Chairperson may appoint one or more appropriately qualified IACUC members to serve as the designated reviewer(s). Designated review may result in approval, a requirement for modifications (to secure approval), or referral to the full committee for review. Designated review may not result in withholding of approval.
If a protocol is assigned more than one designated reviewer, the reviewers must be unanimous in any decision. They must all review identical versions of the protocol and if modifications are requested by any one of the reviewers then the other reviewers must be aware of and agree to the modifications.
The PHS Policy recognizes that the IACUC may approve, require modifications, or withhold approval. If the IACUC determines that a protocol is approvable, contingent on receipt of a very specific administrative modification or clarification (e.g., a contact telephone number), the Committee may handle the issue as an administrative detail that an individual (e.g., IACUC Chair or Administrator) may verify. Requests for substantive modifications should result in the protocol coming back to the Committee. Protocols that lack substantive information necessary for the IACUC to make a judgment (e.g., justification for withholding analgesics in a painful procedure) should be considered incomplete and the IACUC should defer review until the requisite information is provided by the investigator. Applying descriptors, such as conditional, provisional or interim, when referring to IACUC approval is unclear, confusing, and should be avoided. [A2, A11]
IACUCs must confirm that:
- the protocol is consistent with the Guide unless a scientific justification for a departure is presented and is acceptable to the IACUC;
- the protocol conforms with the institution's Assurance;
- the protocol will be conducted in accordance with the USDA Animal Welfare Regulations if applicable; and
- the protocol meets the requirements of the PHS Policy at IV.C.1.a.-g.
For further guidance, the IACUC should refer to the U.S. Government Principles.
Should the IACUC consider the three Rs of alternatives when reviewing protocols? (Refinements to research, Reduction of animal numbers, and Replacement with non-animal models)The federal mandate in U.S. Government Principle IV to avoid or minimize discomfort, distress, and pain in experimental animals consistent with sound scientific practices, is synonymous with a requirement to implement refinements (e.g., less invasive procedures or use of analgesia). Similarly, the mandate in U.S. Government Principle III to use the minimum number of animals necessary to obtain valid results is synonymous with a requirement to reduce animal numbers. U.S. Government Principle III further states that mathematical models, computer simulation, and in vitro biological systems should be considered, and is synonymous with a requirement to replace non-animal models wherever possible. Thus, consideration of the three “Rs” should be incorporated into IACUC review, as well as other aspects of the institution’s program (e.g., investigator training). [D6]
When institutions collaborate, or when the performance site is not the awardee institution, which IACUC is responsible for review of the research activity?
There are many circumstances that involve partnerships between collaborating institutions or relationships between institutional animal care programs. Interinstitutional collaborations have the potential to create ambiguities. Therefore it is imperative that institutions define their respective responsibilities. OLAW and APHIS agree that review of a research project or evaluation of a program or facility by more than one recognized IACUC is not a federal requirement. Institutions should have a formal written understanding (e.g., memorandum of understanding) that addresses responsibilities for animal care and use, ownership, and IACUC review and oversight (Guide page 15).PHS Policy requires that all awardees and performance sites hold an approved Animal Welfare Assurance. If an institution does not have an animal care and use program, facilities to house animals, and an IACUC, the awardee institution will conduct the animal activity at an Assured institution (performance site). Assured institutions also have the option to amend their Assurance to cover performance sites that do not have an approved Assurance with OLAW, which effectively subjugates the performance site to the Assured institution and makes the Assured institution responsible for the performance site.
If both the awardee institution and the performance site institution have Domestic Assurances, they may exercise discretion in determining which IACUC reviews animal activities and under which institutional program the research will be performed. There is no requirement for dual review; IACUCs may choose which IACUC will review protocols for the animal activities being conducted. It is recommended that if an IACUC defers protocol review to another IACUC, documentation of the review should be maintained by both committees. Additionally, the IACUC conducting the review should notify the other IACUC of significant questions or issues raised during a semiannual program inspection of a facility housing a research activity for which that IACUC bears some oversight responsibility.
NIH Grants Policy Statement on Written Agreements (NIH GPS, chapter 15.2.1) requires that awardees have a formal written agreement with consortium participants that addresses the negotiated scientific, administrative, financial, and reporting requirements of the grant. This written agreement must include incorporation of applicable public policy requirements, including agreement for meeting the PHS Policy requirement for review and approval of proposed animal activities, significant changes to animal activities, and semiannual facilities review by an IACUC (IV.B.2.).
Guidance on what is considered a significant change to an ongoing animal activity that requires IACUC review can be found in NIH Guide Notice NOT-OD-14-126 or Significant Changes webpage.
Helpful resource: see OLAW Special Seminar Guidance on Significant Changes to Animal Activities.
PHS Policy and the NIH Grants Policy Statement (NIH GPS, chapter 184.108.40.206) require the institution to verify, before award, that the IACUC has reviewed and approved those components of grant applications and contract proposals related to the care and use of animals. This is not an explicit requirement for the IACUC to do a side-by-side comparison of an application/proposal and the IACUC protocol. However, institutions are responsible for ensuring that the information the IACUC reviews and approves is congruent with what is in the application/proposal. Institutions are free to devise a workable mechanism to accomplish this end. One method to prevent inconsistencies between the information submitted to PHS and that on the IACUC protocol is to implement a procedure for direct comparison. Some institutions have delegated this responsibility to a particular office or position (e.g., sponsored programs or compliance office); others ask departmental chairs to verify consistency. [A11]
Yes. Pilot studies may be appropriate to determine the technical feasibility of larger studies or to make initial assessments of the effect of procedures on animals (Guide pages 26, 28). Whether proposed by investigators or required by the IACUC, pilot studies require review and approval by the IACUC in accordance with the PHS Policy.
Peer review of the scientific and technical merit of an application is considered the purview of the NIH Scientific Review Groups (SRGs), which are composed of scientific experts from the extramural research community in a particular area of expertise. However, SRGs also have authority to raise specific animal welfare concerns that can require resolution prior to a grant award.
Although not intended to conduct peer review of research proposals, the IACUC is expected to include consideration of the U.S. Government Principles in its review of protocols. Principle II calls for an evaluation of the relevance of a procedure to human or animal health, the advancement of knowledge, or the good of society. Other PHS Policy review criteria refer to sound research design, rationale for involving animals, and scientifically valuable research. Presumably a study that could not meet these basic criteria is inherently unnecessary and wasteful and, therefore, not justifiable.
The primary focus of the SRG is scientific merit and the primary focus of the IACUC is animal welfare. The two bodies have differing constitutions, mandates and functions. However, since it is not entirely possibly to separate scientific value from animal welfare some overlap is inevitable. SRGs may raise concerns about animal welfare and IACUCs may question the scientific rationale or necessity for a procedure. [A1]
If an animal activity will be performed outside of the US (either by a foreign awardee or by a foreign institution as a subproject for a domestic awardee), is the awardees IACUC required to review and approve that activity?
When the awardee is a domestic institution (i.e., domestic award with a foreign component), PHS animal welfare requirements are applicable. Accordingly, the awardee remains responsible for animal activity conducted at a foreign site and must provide verification of IACUC approval. That approval certifies that the activity, as conducted at the foreign performance site, is acceptable to the awardee. The awardee IACUC may accept, as its own, the approval of a foreign entity's IACUC; however, the awardee IACUC remains responsible for the review. Additionally, the foreign institution must complete the Animal Welfare Assurance for Foreign Institutions (Foreign Assurance) available from OLAW. This document certifies that the institution will comply with the applicable laws, regulations, and policies of the jurisdiction in which the research will be conducted, and that the institution will be guided by the International Guiding Principles for Biomedical Research Involving Animals (PDF). OLAW encourages, but does not require, foreign institutions to use the standards in the Guide. If the prime awardee is a foreign institution, IACUC approval is not required.
May standard operating procedures (SOPs) or blanket protocols that cover a number of procedures be utilized in lieu of repeating descriptions of identical procedures in multiple protocols?The IACUC must review and approve activities on a project-specific basis, taking into account a number of factors, e.g., the aims of the study, consideration of alternatives, minimization of pain and distress. For routine aspects of research (e.g., species specific techniques for immunization and titer determinations during antibody production), IACUCs may approve SOPs that can be cited by investigators in their protocols in order to avoid needless repetition. SOPs should be reviewed by the IACUC at appropriate intervals (at least once every three years) to ensure they are up-to-date and accurate. (See NOT-OD-14-126)
Is IACUC approval required for the collection of samples in foreign countries from captive wild animals or research colonies?Collection of biological samples from any live vertebrate animal for the purpose of a PHS-supported activity is covered by the PHS Policy. If the awardee is a domestic institution, the IACUC should consider the species involved, nature of the specimens, invasiveness of the procedure, risks to personnel, and qualifications of the individual(s) taking the sample(s). (For further information concerning foreign performance sites see FAQ D13.)
Awardee institutions should also consult with other agencies of the federal government as appropriate, e.g., US Fish and Wildlife Service, USDA-APHIS-Veterinary Services, and the CDC for specimen importation requirements. [A7]
Is IACUC approval required for the use of animals in breeding programs, as blood donors, as sentinels in disease surveillance programs, or for other non-research purposes?Although animals used as sentinels, breeding stock, blood and blood product donors, or for other similar purposes may not be part of specific research protocols, their use is part of the institutional research program and directly supports research activities. Consequently, the IACUC should review protocols and SOPs that involve animals for such purposes, initially and at appropriate intervals (at least once every three years). [A4]
What guidelines should IACUCs follow for fishes, amphibians, reptiles, birds, and other nontraditional species used in research?
PHS Policy is intentionally broad in scope and does not prescribe specifics about the care and use of any species, assigning that task to the IACUC and allowing for professional judgment. Many of the principles embodied in the Guide can generally be adapted to the care and use of various kinds of nontraditional research animals. IACUCs may seek the advice of experts when necessary, and refer to scientific-based publications prepared by professional organizations with interest in various species. Appendix A of the Guide references many such publications. [A7]
Is it acceptable to have different individuals named as PI on the grant application and the IACUC protocol?Yes.
May an IACUC use designated member review (DMR) to review an animal study protocol subsequent to full committee review (FCR) when modifications are needed to secure approval?
When substantive information is lacking from a protocol, the committee may have questions requiring a response from the PI. In such situations, the IACUC may take the following actions:
If a protocol is reviewed and approved by DMR, the IACUC may use the date that the designated reviewer(s) approved the protocol as the date of approval. To facilitate efficient business practice, the IACUC also has the option of selecting a reasonable later approval date as described in NOT-OD-11-053. The approval date will appear in the written notification of approval to the principal investigator. If animal work is conducted before the approval date, as stated in the written notification of approval, this is to be reported to OLAW as a serious noncompliance with the PHS Policy. (PHS Policy IV.F.3)
- If all members of the IACUC are present at a meeting, the committee may vote to require modifications to secure approval and have the revised research protocol reviewed and approved by designated member review, or returned for FCR at a convened meeting.
- If all members of the IACUC are not present at a meeting, the committee may use DMR subsequent to FCR according to the following stipulations:
- All IACUC members agree in advance in writing that the quorum of members present at a convened meeting may decide by unanimous vote to use DMR subsequent to FCR when modification is needed to secure approval. However, any member of the IACUC may, at any time, request to see the revised protocol and/or request FCR of the protocol.
- In order to conduct reviews by DMR subsequent to FCR, the institution should specify its intention to conduct reviews in this manner in its Assurance with OLAW. (IACUCs that newly elect to utilize a standard operating procedure for DMR subsequent to FCR should provide information about this program change to OLAW in the next Annual Report.)
- If all members are not present and the IACUC lacks written standard procedures as described above, the committee has the option to vote to return the protocol for FCR at a convened meeting or to employ DMR. If electing to use DMR, all members, including the members not present at the meeting, must have the revised research protocol available to them and must have the opportunity to call for FCR. A DMR may be conducted only if all members of the committee have had the opportunity to request FCR and none have done so. (PHS Policy IV.C.2)
In response to questions from the community regarding this guidance, OLAW offers the following clarifications:
To avoid temporal delays associated with the PHS Policy requirement that all members of the IACUC must be provided the opportunity to call for FCR for a proposal requiring modifications to proceed to DMR (PHS Policy IV.C.2.), OLAW formally recognized an alternative practice in NOT-OD-09-035 (Guidance to IACUCs Regarding the Use of DMR for Animal Study Proposal Review Subsequent to FCR) issued on January 8, 2009. USDA concurred with this practice.
What is “substantive information”?
“Substantive information” is the information the IACUC needs to evaluate the proposal in accordance with the requirements of the PHS Policy. IACUCs are required to evaluate proposals to ensure that they conform with the institution’s Animal Welfare Assurance and meet the requirements specified in the PHS Policy at IV.C.1., provide the information described in the PHS Policy at IV.D.1., and adhere to provisions of the Guide for the Care and Use of Laboratory Animals. Should a proposal fail to address any of these items to the IACUC’s satisfaction, the Committee may determine that the proposal lacks substantive information and require modifications to secure its approval. Typographical or arithmetic errors, misspellings, incorrect room or telephone numbers, etc., are not considered substantive. While these corrections must be made, additional IACUC review is not required.
Can a quorum of the IACUC decide to establish the DMR subsequent to FCR policy?
No. A DMR subsequent to FCR policy, along with appropriate implementing procedures, may be established only by unanimous consent of all members of the IACUC. While all members need not be physically present at the meeting where the policy is proposed, each individual must be given the opportunity to provide their input in person or via facsimile, email, or memorandum prior to its approval.
What does “in advance, in writing” mean?
“In advance” means that the IACUC-approved policy must be in place prior to the first meeting at which it is used. “In writing” means that the policy and procedures must be written down and documented in the IACUC’s permanent records as having been established by unanimous agreement of all Committee members. Members are not required to physically sign the DMR subsequent to FCR policy.
Does there have to be a written statement for every meeting?
No. The IACUC-approved DMR subsequent to FCR policy allows an appropriately constituted Committee, by unanimous consent, to implement the policy, whenever appropriate, to evaluate revised proposals using DMR. The outcomes of DMRs must then be appropriately documented in the IACUC minutes or elsewhere.
When can the IACUC start using DMR subsequent to FCR?
As soon as all members agree to the process and the IACUC-approved, written DMR subsequent to FCR policy and procedures are in place. In addition, when an IACUC establishes the new policy and procedures, OLAW must be notified in the next institutional Annual Report, and the policy must be documented in the institution’s Assurance renewal.
What happens to the DMR subsequent to FCR policy as the membership of the IACUC changes?
OLAW expects IACUCs to have appropriate standing mechanisms in place to 1) inform new members of all its policies and procedures, and 2) review all IACUC policies and procedures regularly.
- If all members of the IACUC are present at a meeting, the committee may vote to require modifications to secure approval and have the revised research protocol reviewed and approved by designated member review, or returned for FCR at a convened meeting.
Does the IACUC have to review proposed animal research activities at the time of grant award if the animal research activities will not be conducted until year 4 or 5 of a grant?
Yes, with rare exception.
The IACUC must review and approve the proposed use of animals described in the application or proposal prior to the conduct of any PHS-supported animal activity (PHS Policy V.B.). Approval is valid for a maximum of 3 years. A brief description of the animal activities planned for the 4th and 5th year of the award period should be provided in the animal protocol recognizing that the experimental details and procedures will be refined or amended at a later time or at the time of the 3-year renewal.
Because the scientific enterprise is not static, the need for changes to animal protocols is anticipated and can occur at any time during the life of the protocol. Significant changes to previously approved animal activities require prior IACUC approval. For guidance on what is considered a significant change, see FAQ D9.
In rare cases, IACUC review of animal activities is conducted later in the life cycle of a grant or contract. IACUC review may be delayed if the animal activities will not occur until a year or later in the award period as part of the research design described in the grant application or contract proposal (e.g., the initial development of a drug or device with subsequent animal testing projected into the future). In these circumstances, the funding component will issue a Notice of Award with a special term and condition indicating that no funds may be drawn from the grant or contract for animal activities until a valid IACUC approval date has been provided to the funding component.
Additional OLAW Guidance regarding IACUC review of grant applications can be found at FAQ D10, previous OLAW Commentary, and OLAW Online Seminar The 2016 Vertebrate Animals Section, Grants Policy, and Congruence.
Institutions are responsible for oversight of all animal-related activities regardless of how long or where the activity occurs. Satellite facilities (defined by PHS Policy as a containment outside a core or centrally managed area in which animals are housed for more than 24 hours) and areas where any form of surgical manipulations (minor, major, survival, non-survival) are performed must be inspected at least once every six months by the IACUC as part of the semiannual evaluation. Institutions have discretion with regard to how they oversee areas used for routine weighing, dosing, immunization, or imaging, but should monitor such areas on a random or fixed schedule to effectively oversee activities at the institution. USDA requires semi-annual inspection of “animal study areas” defined as areas where USDA covered animals are housed for more than 12 hours. [A1, A7]
PHS Policy requires the IACUC to make this distinction in its semiannual reports to the Institutional Official. A significant deficiency is defined as one which is or may be a threat to the health or safety of animals. Examples include inoperable HVAC, electrical or watering systems, failure of such systems sufficient to affect critical housing and operational areas, and situations such as natural disasters that cause injury, death, or severe distress to animals. Significant program deficiencies can result from an institution's failure to fully understand or implement some aspect of its animal care and use program required by the PHS Policy, or failure to function according to commitments made in its Assurance, and may reach the level of reportable noncompliance. Generally, a minor deficiency refers to a problem for which an immediate solution is not necessary to protect life or prevent distress (e.g., peeling or chipped paint). Ongoing inattention to a minor deficiency may result in a chronic problem indicative of a programmatic failure and may constitute a significant deficiency. [A7]
See paragraph entitled “Utilization of AAALAC activities as Semiannual Program Evaluation” in the NIH Guide for Grants and Contracts NOT-OD-00-007.
While semiannual IACUC inspections of field study sites are not required and in many circumstances are impractical, IACUCs should be apprised of the circumstances under which studies are conducted so that they can consider risks to personnel and impact on study subjects. This may be partially accomplished by written descriptions, photographs, or videos that document specified aspects of the study site. The IACUC should also ensure that appropriate permits are in place. USDA animal welfare regulations exempt areas containing free-living wild animals in their natural habitat from inspection [See Quick Reference Guide: 9 CFR, Part 2, Section 2.31(c)(2)].
See also FAQ A6: Does the PHS Policy apply to research that is conducted in the field?
Although carbon dioxide (CO2) is generally considered an acceptable euthanasia agent for small animals when properly administered, its acceptability is predicated on a number of critical factors as described in the AVMA Guidelines for the Euthanasia of Animals (page 31). The Guidelines recommend that euthanasia chambers be filled at a gradual displacement rate of 30% to 70% to minimize aversion and distress while maintaining CO2 flow for at least one minute after respiratory arrest. It is important to verify death after CO2 exposure, and CO2 narcosis must be followed by a secondary method of euthanasia where necessary. Because immature animals are resistant to the hypoxia-inducing effects of CO2 and require longer exposure times to the agent, alternative methods should be considered, such as injection with chemical agents, cervical dislocation, or decapitation (Guide page 124).
Although the PHS Policy does not explicitly require a mechanism to track animal usage by investigators, it does require that proposals specify a rationale for the approximate number of animals to be used and be limited to the appropriate number necessary to obtain valid results. This implicitly requires that institutions establish mechanisms to document and monitor numbers of animals acquired and used, including any animals that are euthanatized because they are not needed. Monitoring should not exclude the disposition of animals inadvertently or necessarily produced in excess of the number needed or which do not meet criteria (e.g., genetic) established for the specific study proposal. Institutions have adopted a variety of administrative, electronic, and manual mechanisms to meet institutional needs and PHS Policy requirements.
May an investigator transfer animals and research to an institution different than the grantee institution?The transfer of PHS-supported research to a different institution requires the prior approval of the funding component. The proposed new grantee institution must have or obtain an Animal Welfare Assurance and possess all the resources necessary to fulfill the conditions of the grant, and its IACUC must review and approve the animal activities. The original IACUC approval is void when the original grantee formally relinquishes the award. The receiving institution must provide verification of IACUC approval prior to receiving funding. Note that the conditions of approval by the IACUC at the receiving institution may differ from those required by the original grantees IACUC.
OLAW and USDA agree that pharmaceutical-grade1 substances, when available, must be used to avoid toxicity or side effects that may threaten the health and welfare of vertebrate animals and / or interfere with the interpretation of research results2. However, it is frequently necessary to use non-pharmaceutical-grade substances such as investigational substances, veterinarian- or pharmacy-compounded3 substances, and / or Schedule I4 controlled substances to meet scientific and research goals.
The IACUC is responsible for evaluating the potential adverse consequences of non-pharmaceutical-grade substances when used for research. In making its evaluation, the IACUC may consider factors including, for example:
- acid-base balance,
- site and route of administration,
- compatibility of components,
- side effects and adverse reactions,
- storage, and
Although the potential animal welfare consequences of complications are less evident in non-survival studies, the scientific issues remain the same. The principles and need for professional judgment outlined above apply to non-survival studies.
Procedures that may cause more than momentary or slight pain or distress to animals must be relieved by sedation, analgesia, or anesthesia using veterinary or human pharmaceutical-grade substances, unless the use of a non-pharmaceutical-grade substance is scientifically necessary, appropriately justified, and approved by the IACUC. The use of a non-pharmaceutical-grade euthanasia agent must meet the same criteria.
1 A pharmaceutical-grade substance is any active or inactive drug, biologic, reagent, etc., manufactured under Good Manufacturing Practices (GMP) which is approved, conditionally approved, or indexed by the Food and Drug Administration (FDA) or for which a chemical purity standard has been written or established by a recognized compendia (e.g., United States Pharmacopeia-National Formulary (USP-NF), British Pharmacopeia (BP) ).
2 A listing of pharmaceutical-grade drugs and biologics is available through the FDA database. The Orange Book is the reference for FDA-approved human drugs. The Green Book is the reference for FDA-approved veterinary drugs.
3 Veterinary compounding is the customized manipulation of an approved drug by a veterinarian, or by a pharmacist upon the prescription of a veterinarian, to meet the needs of a research study. IACUCs considering the use of veterinary compounding for research purposes are advised to consult: https://www.avma.org/KB/Resources/Reference/Pages/Compounding.aspx for more information about federal regulations.
4 United States Department of Justice Drug Enforcement Agency controlled substances Schedule I and II-IV drugs may be used in biomedical research according to the standards of the Code of Federal Regulations 1301.13.
The use of expired pharmaceuticals, biologics, and supplies is not consistent with acceptable veterinary practice or adequate veterinary care. Euthanasia, anesthesia and analgesia agents should not be used beyond their expiration date, even if a procedure is terminal. Other expired materials should not be used unless the manufacturer verifies efficacy beyond the expiration date, or the investigator is able to document to the satisfaction of the IACUC that such use would not negatively impact animal welfare or compromise the validity of the study. The veterinarian and IACUC must maintain control over the use of expired medical materials in order to meet their responsibilities to avoid or minimize discomfort, pain or distress to animals.
Institutions that conduct PHS-supported research, testing, or training have a responsibility to ensure animal welfare and an obligation to protect the federal investments in these activities. The Guide provides recommendations regarding temperature, humidity, and ventilation for common laboratory animals and discusses parameters regarding heating, ventilating, and air conditioning (HVAC) that must be considered. It also states, “In the event of an HVAC system or component failure, systems should, at a minimum, supply facility needs at a reduced level, address the adverse effects of loss of temperature control, and, where necessary, maintain critical pressurization gradients. It is essential that life-threatening heat accumulation or loss be prevented during mechanical failure.” (Guide page 140) Monitoring HVAC equipment performance is important to ensure timely identification of local or regional power disruptions or system malfunctions. Institutions are strongly encouraged to consider using available electronic technology to measure temperature in each animal room on a continuous basis. Appropriately installed and powered sensors and electronic alarm systems can rapidly notify maintenance and animal care staff of the need to take immediate action to prevent harm to animals (Guide page 143). Sole reliance on employees to identify changes in animal room conditions or the use of high-low thermometers to track changes in temperature may not be sufficient to allow timely intervention and prevent catastrophic loss.
Institutions are also responsible to ensure the welfare of fishes, amphibians, and other vertebrates whose environment is aquatic, with the emphasis on water temperature and quality, including oxygenation, circulation and filtration. (Guide pages 77-88)
The Guide requires that institutions develop a plan that can be instituted if a disaster occurs. (Guide pages 35, 74-75) The disaster plan must include a scheme for relocating or euthanizing animals when power cannot be restored or repairs effected promptly. HVAC, alarm malfunctions, failures in primary and emergency power sources, mechanisms for maintaining appropriate temperatures and ventilation are important issues that must be considered and included in the disaster plan. OLAW provides a Disaster Planning and Response Resources web page to assist institutions in planning and responding to natural and other disasters affecting animal facilities.
See also FAQ G3: Do awardee institutions need animal facility disaster plans?
The Guide requires that aseptic technique be followed for all survival surgical procedures. The manner in which asepsis is achieved varies by species. Modification of standard techniques may be desirable or even required, but should not compromise the well-being of the animals. “The design of a surgical facility should accommodate the species to be operated on and the complexity of the procedure to be performed.” (Guide page 144) For most rodent survival surgery, “an animal procedure laboratory is recommended; the space should be dedicated to surgery…and appropriately managed to minimize contamination from other activities conducted in the room at other times.” (Guide page 144)
The NIH concurs with the findings and recommendations in the 1999 report of the National Research Council Monoclonal Antibody Production (PDF) which indicates that during the accumulation of ascites there is likely to be pain and distress, particularly when some cell lines that are tissue-invasive are used and in situations of significant ascites development. The Report concluded that there is and will continue to be scientific necessity for this method, but that as tissue-culture systems are further developed, tissue-culture methods for the production of monoclonal antibodies should be adopted as the routine method unless there is a clear reason why they cannot be used.
Accordingly, IACUCs are expected to critically evaluate the proposed uses of the mouse ascites method. Prior to approval of such protocols, IACUCs must determine that (i) the proposed use is scientifically justified, (ii) methods that avoid or minimize discomfort, distress, and pain (including in vitro methods) have been considered, and (iii) the latter have been found unsuitable. [D6]
Surgical procedures should be defined as major or minor on a case-by-case basis and evaluated by the veterinarian and IACUC to determine their impact on the animal’s well-being. (Guide pages 30, 117) Multiple procedures that may induce substantial post-procedural pain or impairment may be conducted on a single animal only if justified by the PI, and reviewed and approved by the IACUC. Multiple major surgical procedures on a single animal are acceptable only if they are:
- included in and essential components of a single research project or proposal;
- scientifically justified by investigator;
- or necessary for clinical reasons. (Note, clinically necessary procedures do not necessarily require review and approval by the IACUC in advance of the procedure.)
Cost savings alone are not an adequate justification for performing multiple major survival surgical procedures. (Guide page 30)
Note that under USDA regulations (AWR 2.31 (x) A-C), “No animal will be used in more than one major operative procedure from which it is allowed to recover, unless: (A) Justified for scientific reasons by the principal investigator, in writing; (B) Required as routine veterinary procedure or to protect the health or well-being of the animal as determined by the attending veterinarian; or (C) In other special circumstances as determined by the [Animal Care] Administrator on an individual basis. Written requests and supporting data should be sent to the Animal and Plant Health Inspection Service, Animal Care, 4700 River Road, Unit 84, Riverdale MD 20737-1234”.
See also FAQ F13: Are laparoscopic procedures considered major surgery?
Can performance standards be used in determining rodent housing practices including management of rodent breeding colonies?
Performance standards are to be applied to rodent housing issues. (See Guide pages 56-58.) While the Guide's space recommendations are accepted reference points for addressing space needs, performance standards allow flexibility to improve animal welfare and scientific research. Adjustments to recommendations for primary enclosures may be made at the institutional level by the IACUC. The IACUC should critically evaluate objective measures of outcome-based performance. The Guide identifies examples of performance indices to assess adequacy of housing including:
- activity, and
- use of space.
Rodent cages of the size commonly used in the United States may be appropriate for pair or trio breeding. The Guide does not add specific, additional engineering standards for breeding configurations. This empowers institutions to determine appropriate housing. The IACUC must consider relevant factors when assessing the adequacy of cage space according to performance standards. Examples of these factors may include:
- average litter size of the strain(s) of rodents;
- whether multiple litters are present in the cage;
- difference in the age of the pups of different litters;
- growth rate;
- need for cross-fostering;
- cage dimensions; and
- overall management and husbandry practices such as cage sanitation or bedding change.
Blanket, program-wide departures from the Guide for reasons of convenience, cost, or other non-animal welfare considerations are not acceptable. Cages that might be acceptable when litters are born may have insufficient space as pups grow. Whatever parameters are used to establish breeding configurations and weaning procedures, the IACUC must ensure that cage population does not negatively impact animal well-being and overcrowding does not occur.
Can IACUCs authorize the adoption of research animals as pets after the animals are no longer needed for study?
The PHS Policy and the Guide are silent on the issue of private adoption of research animals for pets after a study has been completed and the animals are no longer required. For purposes of property standards under the uniform administrative requirements for HHS grant awards, animals purchased for research purposes are considered to be supplies. Generally, the title to supplies vests with the grant recipient upon acquisition (2 CFR § 200.314). OLAW supports the safety and protection of animals and reminds institutions that their policies must clarify the disposition of animals acquired for research once the research has ended, which may include adoption. The PHS will not assume legal or financial responsibility for any adoption program or any matters arising from or related to the adoption of research animals. The institution should ensure that its policy meets pertinent state and local laws and regulations for the transfer of animal ownership and is encouraged to coordinate with local animal shelters.
What are the institutions responsibilities in ensuring that animals are shipped safely and in reporting adverse events that occur in shipment of animals to or from the institution?
Animals should be transported according to international, federal, state and local regulations summarized in the Guide (page 107). Needs of the animals and protection of personnel should be considered in advance of transportation and met during loading, transportation and unloading, as described in the Guide (pages 107-109).OLAW expects all parties involved in the transportation of animals to apply due diligence in assuring that animals are shipped under appropriate conditions to prevent morbidity or mortality due to temperature extremes or other adverse events. When animals are shipped from an institution, that institution should consider and address all relevant factors to ensure safe transport of the animals. OLAW expects shipping institutions to report adverse events that occur to animals in transit. Receiving institutions should notify the shipping institution when animals are received in extremis or dead.
Surgical procedures can be categorized as major or minor. (See Guide page 117.) Major survival surgery penetrates and exposes a body cavity, produces substantial impairment of physical or physiologic functions, or involves extensive tissue dissection or transection (e.g., laparotomy, thoracotomy, joint replacement, and limb amputation). Minor survival surgery does not expose a body cavity and causes little or no physical impairment (e.g., wound suturing, peripheral vessel cannulation, percutaneous biopsy, and most procedures routinely done on an outpatient basis in veterinary clinical practice). Animals undergoing a minor survival surgical procedure typically do not show significant signs of postoperative pain, have minimal complications, and quickly return to normal function.
OLAW recognizes the authority of the IACUC to determine whether specific manipulations used in research are major operative procedures. The IACUC’s determination must be based on a detailed description of the procedure and the anticipated or actual consequences, as characterized by the investigator. In some cases, the classification by the IACUC of a procedure as major or minor may be readjusted post-procedurally depending on clinical outcome. If the IACUC, after thorough review, determines that the surgical procedure only penetrates but does not expose a body cavity and that the procedure does not produce substantial impairment, the IACUC may conclude that it is not a major operative procedure. Any laparoscopic surgery that produces substantial impairment of physical or physiological function must be considered a major operative procedure. Whether the laparoscopic procedure is classified as major or minor, the IACUC must ensure that the appropriate analgesia, sterile technique, and perioperative monitoring is employed.
Multiple major survival surgical procedures on a single animal are discouraged but may be permitted if they are related components of a research project, are scientifically justified by the investigator, or if they are needed for clinical reasons. Cost savings alone is not an adequate reason for performing multiple major survival surgical procedures.
See also FAQ F9: Are multiple major surgical procedures permitted on a single animal?
There is universal agreement among oversight agencies that nonhuman primates should be socially housed. (See U.S. Government Principles for the Utilization and Care of Vertebrate Animals Used in Testing, Research, and Training Principle VII.) The Guide endorses social housing as the default for nonhuman primates. (Guide page xviii) The USDA requires regulated facilities to address the social needs of nonhuman primates known to exist in social groups in nature [See 9 CFR 3.81(a)], with certain specified exceptions [See 9 CFR 3.81(a)(1),(2), and (3) and 3.81(e)(1) and (2)]. Single housing of social primates is considered an exception to the standards under 9 CFR and must be reported as such in a research facility’s annual report [See 9 CFR 2.36(b)(3)].
Staff performing nonhuman primate socialization should be trained and competent in the procedure and knowledgeable about the animals. Behaviorally compatible animals should be used whenever possible in socialization attempts. Group composition is critical and numerous species-specific factors should be taken into consideration when forming a group. Due to conformational differences of animals within groups, more space or height may be required to meet the animals’ physical and behavioral needs. Determination of the appropriate cage size is not based on body weight alone. Professional judgment is paramount in making such determinations. (See Guide pages 58-61.)
Exemptions to the social housing requirement must be based on strong scientific justification approved by the IACUC or for a specific veterinary or behavioral reason. Lack of appropriate caging does not constitute an acceptable justification for exemption. When necessary, single housing of social animals should be limited to the minimum period necessary. When single housing is necessary, visual, auditory, olfactory, and (depending on the species) protected tactile contact with compatible conspecifics should be provided, if possible. (Protected tactile contact is considered single housing by USDA, with rare exceptions.) In the absence of other animals, additional enrichment should be offered (as appropriate to the species or individual animal), such as safe and positive interaction with the animal care staff, periodic release into larger enclosures, supplemental enrichment items, and/or the addition of a companion animal in the room or housing area.
Institutions are encouraged to consult the Animal Welfare Act and Regulations on primate housing requirements. Compliance with the USDA regulations is an absolute requirement of this [PHS] Policy. (Footnote 2, page 9) OLAW and USDA positions are further defined at the Nonhuman Primate Enrichment and Social Housing resource on the OLAW website.
In situations where it is safe and feasible, nonhuman primates should be given positive reinforcement training to perform desired cooperative activities involved with research and husbandry. This type of training may also aid in reducing stress from capture and restraint and the need for chemical darts. The Guide comments on procedural habitation and training on pages 64-65.
Performance standards are to be applied to housing issues. Outcome-based performance standards are paramount when evaluating cage or pen space for housing animals used for research, research training, and biological testing. While the Guide's space recommendations are accepted reference points for addressing space needs (Guide pages 50-63), performance standards allow flexibility to improve animal welfare and scientific research. (Guide pages 6-7) An institution’s animal housing practices must be species-specific, appropriate for the animals, and in compliance with all applicable federal and local regulatory requirements. Compliance with the applicable regulations (9 CFR Subchapter A) issued by the U.S. Department of Agriculture under the Animal Welfare Act are an absolute requirement of the PHS Policy (Footnote 2, page 9).
An institution’s environmental enrichment practices must be species-specific and appropriate for the animals. Devices that animals climb on or through, perch on, or nest in contribute to, rather than detract from, the animal’s living space and need not be subtracted from the floor dimensions. Some species are upset by the introduction of novel items. Animals should not be subjected to the presence of items that they find distressing. (See Guide pages 52-54.) Compliance with the applicable regulations (9 CFR Subchapter A) issued by the U.S. Department of Agriculture under the Animal Welfare Act are an absolute requirement of the PHS Policy (Footnote 2, page 9).
OLAW concurs with the Guide that animals “should be housed under conditions that provide sufficient space…to meet physical, physiologic, and behavioral needs.” (Guide pages 50-51) “The height of an enclosure can be important to allow for expression of species-specific behaviors and postural adjustments. Cage height should take into account the animals’ typical posture and provide adequate clearance for the animal from cage structures, such as feeders and water devices.” (Guide page 56) Space allocations should be assessed, reviewed, and modified as necessary by the IACUC considering the performance indices and special needs determined by the characteristics of the animal (Guide page 56). IACUCs may consider the use of a rabbit cage that is 14 inches in height, if appropriate for specific animals. The IACUC should establish, through performance indices related to animal well-being, that the cage provides sufficient space to meet the physical, physiologic and behavioral needs of the animal. For example, the rabbit must be able to hold its ears in an upright position (if this is natural for the breed) and ears must not be forced to fold over by contact with the cage ceiling.
Ingestion of food and fluid are requirements for proper nutrition. When food or fluid is restricted, the amount of the regulated item earned during testing and the amount of the regulated item freely given should be recorded to ensure each animal receives its minimum daily requirements. (NRC 2003, Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research, Washington: National Academies Press) The IACUC must evaluate the level of restriction and potential adverse consequences in regulating food or fluid. The IACUC must also evaluate the methods for assessing the health and well-being of animals involved in activities that regulate food or fluid consumption. The IACUC has the authority to approve scientific justifications for departures from the recommendations in the Guide. For instance, using scheduled access to food or fluid sources may be justified by describing procedures based on performance standards that assure adequate maintenance of hydration, body weight, and behavioral and clinical health. It may be necessary to monitor both food and fluid intake if regulation of one influences consumption of the other. The Guide discusses food and fluid restriction on pages 30-31.
What kind of training is necessary to comply with PHS Policy, and how frequently should it be provided?The U.S. Government Principles1, Health Research Extension Act of 19852 and the PHS Policy3 repeatedly refer to appropriately trained, qualified, and experienced personnel, and availability of instruction and training. The institution is responsible for the training of its staff. The size and nature of institutional research programs varies significantly and accounts for the corresponding variation in the scope and depth of instructional programs and the frequency at which they are offered.
Discussion of appropriate training is found throughout the five chapters of the Guide. At a minimum, the PHS Policy and the Guide (page 15) require institutions to:
- ensure that individuals who use or provide care for animals are trained and qualified in the appropriate species-specific housing methods, husbandry procedures, and handling techniques;
- ensure that research staff members performing experimental manipulation, including anesthesia and surgery, are qualified through training or experience to accomplish such procedures humanely and in a scientifically acceptable fashion;
- provide training or instruction in research and testing methods that minimize the number of animals required to obtain valid results and minimize animal distress;
- ensure that professional staff whose work involves hazardous biological, chemical, or physical agents have training or experience to assess potential dangers and select and oversee the implementation of appropriate safeguards; and
- ensure compliance with any initial and continuing education regarding State requirements for the licensing of veterinary or animal health technicians.
1 The U.S. Government Principles direct that, “…housing, care, and feeding…must be directed by a veterinarian or other scientist trained and experienced in the proper care, handling, and use of the species being maintained or studied” (VII) and that, “Investigators and other personnel shall be appropriately qualified and experienced for conducting procedures on living animals. Adequate arrangements shall be made for their in-service training, including the proper and humane care and use of laboratory animals” (VIII).
2 The Health Research Extension Act of 1985 requires that, “scientists, animal technicians, and other personnel involved with animal care, treatment, and use…have available to them instruction or training in the humane practice of animal maintenance and experimentation…” (Sec. 495.(c) (1) (B)).
3 The PHS Policy requires that institutions seeking an Assurance provide “a synopsis of training or instruction in the humane practice of animal care and use, as well as training or instruction in research or testing methods that minimize the number or animals required to obtain valid results and minimize animal distress, offered to scientists, animal technicians, and other personnel involved in animal care, treatment or use” (IV.A.1.g.); that medical care for animals will be provided by “qualified” veterinarians (IV.C.1.e.) and that, “Personnel conducting procedures on the species being maintained or studied will be appropriately qualified and trained in those procedures” (IV.C.1.f.).
The PHS Policy requires a “health program for personnel who work in laboratory animal facilities or have frequent contact with animals” (IV.A.1.f.). The Guide states that, “Each institution must establish and maintain an occupational health and safety program as an essential part of the overall Program of animal care and use…The nature of the OHSP will depend on the facility, research activities, hazards, and animal species involved.” (Guide pages 17-23)
“A comprehensive OHSP should include a hierarchy of control and prevention strategies that begins with the identification of hazards and the assessment of risk associated with those hazards.” (Guide page 18) An effective occupational health and safety program must encompass all personnel that have contact with animals. Depending on the species of animal or the amount of animal exposure, the program may not affect all personnel equally. Minimally, the program must include:
- pre-placement medical evaluation;
- identification of hazards to personnel and safeguards appropriate to the risks associated with the hazards;
- appropriate testing and vaccinations;
- training of personnel regarding their duties, any hazards, and necessary safeguards;
- policies and facilities that promote cleanliness;
- provisions for treating and documenting job-related injuries and illnesses;
- facilities, equipment, and procedures should be designed, selected, and developed to reduce the possibility of physical injury or health risk to personnel;
- good personal hygiene practices, prohibiting eating and drinking, use of tobacco products, and application of cosmetics and/or contact lenses in animal rooms and laboratories; and
- personal protective equipment (PPE).
Occupational Health and Safety in the Care and Use of Research Animals, published in 1997 by the National Research Council, includes helpful guidelines and references for establishing and maintaining an effective and comprehensive program.
The Guide (pages 35, 74-75) requires that institutions develop disaster plans that take into account the well-being of animals and personnel during unexpected events. Conducting a risk assessment will help to identify potential major hazards and threats, such as power outages, HVAC malfunctions, and natural disasters. Considering the geographic location of a facility “may provide guidance as to the probability of a particular type of disaster” (Guide page 35). Location-based risk should be accounted for in the disaster plan with mitigation strategies to address all known vulnerabilities.
The disaster plan “should define the actions necessary to prevent animal pain, distress, and deaths” (Guide page 35). Institutions may find consideration of the following components useful in the development of a comprehensive, effective plan:
- Backup systems for maintaining appropriate temperatures and ventilation if critical systems fail, including HVAC and alarms
- Schemes for transportation and relocation, or euthanasia of animals
- Provision of food, water, sanitation, and bedding during the disaster period
- Provision of services during significant personnel absences
- Establishment of institutional policies and procedures
- Approval of the plan as a part of the overall institutional and/or local disaster plan
- Identification of emergency responders and designation of responsibilities
- Personnel training and practice in the disaster response
- Utility needs in the event that primary and emergency power sources fail.
Institutions should periodically review and update the plan to adapt to program changes, evolving risk, and lessons learned from drills and actual disasters. Recent hurricanes and tropical storms provide lessons on the unpredictable nature and devastating effects of extreme weather events. Examples of the impact of these events include loss of animals located in basement facilities due to flooding, failure of back-up generators and loss of fuel supplies located in low-lying areas due to flooding, and loss of frozen reagents/specimens due to sustained power outages. Institutions are encouraged to continually re-assess their vulnerabilities as future climate changes are expected to cause higher sea levels and effect precipitation patterns and the severity of storms.
Disasters can happen at any time. With advance preparation, institutions may be able to lessen or eliminate the impact before a disaster occurs. Actions to consider are relocating animals from facilities located in storm surge areas or locations prone to flooding, cryopreserving valuable strains of animals, repositioning emergency power supplies, and backing up vital records in an off-site location.
OLAW provides a Disaster Planning and Response Resources webpage to assist institutions in planning and responding to natural and other disasters affecting animal facilities.
Direct, clear and straight forward lines of responsibility and corresponding authority function well and allow organizations to respond quickly and effectively when necessary. Key components in such organizations are the Institutional Official (IO), the IACUC, and the attending veterinarian. The IO should have the authority to allocate organizational resources needed to maintain a smoothly functioning animal care and use program based on recommendations and advice received from the IACUC and the veterinarian. The IO should also clearly define and assign responsibilities and reporting channels for other essential program elements such as training and occupational health. The IACUC, appointed by the organization's chief executive officer, reports directly to the IO and is empowered to perform its duties without undue interference. It is recommended that the veterinarian report directly to the IO in connection with his or her responsibilities for implementing those parts of the animal care and use program that are set forth in the PHS Policy, the Animal Welfare Act, and the Guide. [A2]
The Institutional Official (IO) signs the Assurance and is the person in the organization with the administrative and operational authority to commit institutional resources to ensure that the animal care and use program will comply with the requirements of the PHS Policy. The PHS Policy requires the chief executive officer (CEO) to appoint the IACUC in accord with specified qualifications and membership criteria, although the CEO may delegate this authority in writing. In some institutions, the IO and the CEO may be one and the same, whereas in other institutions, particularly large ones, the CEO may be further removed from the day-to-day program oversight. [A7]
Continuing IACUC oversight of animal activities is required and can be accomplished through a variety of mechanisms. (Guide pages 33-34) Monitoring animal care and use is required by the PHS Policy, but the Policy does not explicitly require specific post approval monitoring (PAM) procedures to compare the practices described in approved protocols and SOPs against the manner in which they are actually conducted. IACUCs are charged, however, with program oversight and as such are responsible for program evaluations, reviews of protocols, reporting noncompliance, ensuring that individuals who work with animals are appropriately trained and qualified, and addressing concerns involving the care and use of animals at the institution. The veterinarian with program authority and responsibility for animal activities along with the animal care and technical staff, add another important level of program supervision.
Related components of institutional programs provide monitoring by a multi-disciplinary team of individuals. Examples of such components include daily observation of animals by trained animal care personnel and communication to the veterinary staff for follow-up, facility monitoring by facility maintenance personnel, post operative care by trained personnel, evaluation of outcomes of animal procedures by investigators and staff, hands-on training in animal procedures, and appropriate reporting of incidents involving occupational health and safety. All of these functions and responsibilities imply a level of monitoring. Ultimately the institution has flexibility in how it achieves compliance.
Some institutions have developed PAM programs with dedicated staff that physically monitor procedures and practices associated with animal use protocols. This is one acceptable method that institutions may elect to adopt, but it is not a federally mandated requirement. Whatever methods an institution incorporates, it is important that the authority and responsibility of the IACUC not be contravened by a PAM program, institutional compliance officials, or other mechanism established to monitor animal care and use.
May institutions utilize the Guide for the Care and Use of Agricultural Animals in Research and Teaching (Ag Guide) if their programs include traditional farm animals?
PHS Policy mandates that institutions use the Guide for the Care and Use of Laboratory Animals (Guide) as a basis for developing and implementing a program for activities involving animals. The Guide states that it “…applies to agricultural animals used in biomedical research, including those maintained in typical farm settings.” It further emphasizes that the use of farm animals in research should be subject to the same ethical considerations as the use of other animals in research. (Guide, page 32)
The Guide for the Care and Use of Agricultural Animals in Research and Teaching (Ag Guide) primarily refers to agricultural animals used in agricultural research for which the scientific objectives are to improve understanding of the animals’ use in production agriculture. It is therefore inappropriate to substitute the Ag Guide for the Guide based on the species of animal. However, there may be circumstances where it is appropriate to follow the standards of the Ag Guide in biomedical research (e.g., transmission studies of avian influenza under poultry production conditions). Information about environmental enrichment, transport, and handling in the Ag Guide may be helpful in both agricultural and biomedical research settings. Proposals to conduct such activities should be reviewed on a case-by-case basis and any approval to depart from provisions of the Guide must be based on scientific justifications acceptable to the IACUC.
Acts of vandalism and the threat or use of violence are tactics used by some animal rights extremist groups. Such actions endanger lives, cause millions of dollars in damage and destruction, and jeopardize biomedical research, training and biological testing. These actions are considered domestic terrorism by the FBI and are a source of serious concern for NIH and the awardee community. The Guide requires that institutions develop a plan that can be instituted if a disaster occurs. (Guide pages 35, 74-75). Additional detailed guidance on how IACUCs and Institutional Officials can prepare and protect their institution can be found in the ARENA OLAW Institutional Animal Care and Use Committee Guidebook (page 71):
“Since the IACUC has responsibility for the welfare of animals at its facility, it shares responsibility for the security of the animals and associated personnel with other groups within the institution, including the units responsible for security, public information, and governmental relations. Institutions receiving federal funds have an obligation to protect the federal investment in research by exercising due diligence in this area. The IACUC can serve a key role in advising the IO and the institution of potential risks and vulnerabilities, and in developing a plan for responding to potential or real threats. In all cases the IACUC must consider allegations of noncompliance or animal welfare issues as concerns that must be addressed in accordance with relevant PHS Policy provisions and Animal Welfare Regulations (AWRs). There are four key elements to an institution's preparedness:
- An animal care and use program of impeccable integrity;
- A security program based on risk assessment;
- An integrated communication plan with descriptions of research projects in lay terminology, spokespersons, and a telephone tree; and
- An internal and external community outreach program that includes legislators and funding agencies.”
The ARENA OLAW Institutional Animal Care and Use Committee Guidebook goes on to describe in more detail the elements of a crisis management plan and how the institution should best prepare to respond to allegations in an honest and forthcoming fashion. OLAW encourages IOs and IACUCs to evaluate their institution's readiness to deal with potential threats in accordance with the Guidebook's recommendations. OLAW shares the concerns of Institutional Officials and IACUC members about the threats and intimidation their institutions may face and strongly encourages each institution, if it has not already done so, to:
- Operate its program of animal care and use and its animal research facilities in accordance with its approved Animal Welfare Assurance, provisions of the PHS Policy and recommendations of the Guide.
- Examine its portfolio of research and determine those activities that may be potentially targeted.
- Ensure that the institutional security group works closely with local and state law enforcement to make certain that responses to illegal activities are prompt and adequate.
- Develop a crisis management plan that safeguards the institution, prepares it to respond with openness about the research being conducted, and educates employees on how to protect their families and their personal property.
Inform the program/scientific staff of the NIH funding component of threatening or potentially threatening situations, as they arise. (If activist activities result in conditions that jeopardize the health or wellbeing of animals or result in actual harm or death to animals, the conditions must be reported to OLAW in accordance with NOT-OD-05-034.)
Institutions must adhere to provisions of the PHS Policy, the Guide, and the commitments detailed in their Animal Welfare Assurance with OLAW. This includes advance planning for conditions that could arise as a result of a human pandemic (e.g., influenza) or outbreaks of novel infections (e.g., coronavirus disease 2019) that could jeopardize the health and wellbeing of animals because of a lack of personnel to care for the animals and/or to conduct IACUC official business.
Pandemic plans developed by institutions and IACUCs should include consideration of the following:
- Animal facilities must be maintained at a level to ensure animal welfare. Plans should consider appropriate staffing levels, cross-training to cover critical operations, and adequate inventories of essential supplies (e.g., feed, bedding, personal protective equipment, cagewash supplies).
- The IACUC should develop a plan for conducting official business during a pandemic event, taking into account the following:
- The IACUC must continue to be properly constituted.
- A quorum is required to conduct official business at a convened meeting.
- The IACUC must ensure that protocol approvals are not allowed to expire or if they do expire, that no further animal activities (e.g., data collection) are conducted.
- Appointment and training of IACUC members (including nonscientific members and alternates) should be considered as a part of the plan. (See NOT-OD-01-017)
In devising a pandemic plan, the institution may wish to consider using options provided in the PHS Policy that it does not choose to use in the normal operation of its animal care and use program. Social distancing means focused measures to reduce contact among people. The PHS Policy contains some provisions that can be instituted as social distancing measures to prevent the spread of disease, including:
- The IACUC may institute alternatives to face-to-face meetings such as teleconference or video conferencing (NOT-OD-06-052).
- The number of IACUC meetings may be reduced to as few as one every six months.
- The IACUC may choose to expand their use of designated member review.

Additional guidance will be developed and posted on the OLAW website if an emergency situation is sufficiently severe and long-lasting that OLAW determines that the above suggestions do not meet the needs of the research community and funding components. OLAW is the only entity authorized to make determinations regarding waivers to provisions of the PHS Policy.
OLAW encourages the cooperative application of diverse expertise to develop outcome-based performance standards that enhance the quality of animal care and use programs. OLAW does not consider a performance standard to be a departure from the Guide. A well-developed performance standard meets the following criteria:
- supports scientific objectives;
- supports the health and welfare of the animal;
- includes a justified performance index; and
- has associated outcome criteria.
IACUCs are able to meet their responsibility to ensure humane animal care and use while advancing quality scientific research through the use of performance standards.
Animal welfare and the integrity of research findings, rather than cost alone, should be the primary factors in decisions related to assuring compliance with the recommendations in the Guide in PHS-funded research. (See U.S. Government Principles for the Utilization and Care of Vertebrate Animals Used in Testing, Research, and Training Principle II.) The PHS Policy and the Guide define the minimum standards (“musts”) and performance standards (“shoulds”) that OLAW expects of Assured institutions. In many instances, institutions and IACUCs elect to exceed the standards described in the Guide. This is not required and can add expense to the program. OLAW does not discourage or encourage institutions from exceeding the standards.
