January Lab Animal Column: Emotional Support for Everyone

Posted Date
Body

During a post-approval monitoring visit, a staff member notices that an investigator has five pet rats in his office. The rats had been purchased from a pet store and were kept separate from other animals at the institution. The investigator explains that the rats are emotional support animals (ESAs) and claims that the animals are not subject to IACUC review. Is the investigator correct, and what should the institution consider when responding to the situation?

Registration for the January OLAW Webinar is OPEN! Congruence Review

Posted Date
Body

January 18, 2024 | 3:00 PM –4:00 PM | Virtual 

Join us as we explore the topic of congruence review. Congruence review is required prior to award (e.g., grants, cooperative agreements, contracts) for activities that involve the use of live vertebrate animals per PHS Policy IV.D. It is the process that ensures that the information in IACUC protocols is consistent with the application to be awarded, and is an institutional responsibility. This OLAW Online Seminar will cover the foundations of congruence review, including definitions, requirements, flexibilities, and answers to common compliance questions. We will also discuss institutional perspectives on approaches to fulfil this requirement.

Speakers include: 

Cephalopods in Research

Cephalopods in Research

The use of cephalopods in research is a growing field, and the following resources are provided to assist institutions in maintaining good animal welfare when working with these species.

Request for Information

OLAW requested input on proposed guidance for use of cephalopods in research, research training, experimentation, or biological testing or for related purposes between September 8, 2023 and December 22, 2023.  

The proposed text can be found here: NOT-OD-23-176

The comment period is now closed.

The final text will be published once comments have been considered.

What are Cephalopods?

Cephalopods are a class of invertebrate aquatic animals that includes octopuses, nautiluses, squid, and cuttlefish. These animals belong to the phylum Mollusca, which includes several other invertebrate species such as bivalves and snails. Distinguishing features of cephalopods include a head-like structure, arms and/or tentacles, and a hard beak structure. There are over 800 known species of cephalopods worldwide. 

 

Cephalopods in Research

Cephalopod research has been conducted for over 100 years. These studies have provided valuable insight into the science of learning, motion and movement, behavior, and nervous system development. Recent initiatives to formalize standards for cephalopod care and use are helping to ensure continued humane treatment and honor the principles of the 3Rs: Replacement, Reduction, and Refinement.

Useful External Guidelines

The following list provides a limited collection of guidelines for the care and use of cephalopods authored by various institutions and professional associations worldwide. While not considered official guidance for Assured Institutions by OLAW, the information presented in these references may be useful in designing high-quality programs that ensure good animal welfare.

Databases and Organizations

The following additional links provide the names of databases and professional organizations that promote responsible use of cephalopods in research:

Compliance Unit Standard Procedure (CUSP) Sharing Site

The Compliance Unit Standard Procedure (CUSP) Sharing Site is an online repository where participating institutions can share standard procedures used in animal care protocols, supporting the development of high-quality protocols, while reducing burden for researchers, IACUCs, and IACUC support staff. The goal is to assist institutions to easily build a library of standard procedures to use for multiple purposes, such as variations on commonly used techniques, practical information for non-typical species, and methodology used in wildlife studies. Access will initially be limited to FDP (Federal Demonstration Partnership) member institutions (includes ~200 institutions), but the site will ultimately be available to all institutions.

 

Laws, Policies, and Guidance

Laws and Policies

Though cephalopods are not covered under the PHS Policy on Humane Care and Use of Laboratory Animals (PHS Policy), institutions are expected to adhere to the U.S. Government Principles for the Utilization and Care of Vertebrate Animals Used in Testing, Research, and Training for humane care and use of all animals in their care. In addition, because cephalopods are not vertebrate animals, they are not currently subject to the requirements for reporting and there is no requirement to submit a Vertebrate Animals Section for cephalopod use in funding applications.

Alternatives to Animals

Your experimental designs are coming into focus. Sample sizes…power analyses…and treatment conditions, oh my! And, all throughout, perhaps laboratory animals are needed. But, are they? Can you actually replace them and still rigorously test the hypothesis? If not, maybe the protocol can be refined in such a way to reduce their overall numbers, while still ensuring their humane care and use?
