Institutional Animal Care and Use Committee (IACUC): Policy for Assigning Animals to Pain and Distress Categories

Policy No. Issue Date Effective Date
10.10.23

1.0 Policy Purpose

The purpose of this policy is to ensure IACUC protocols are prepared and approved in accordance with requirements for assigning United States Department of Agriculture (USDA)-covered species and species used under Department of Defense (DoD) and the Office of Naval Research (ONR) funded protocols to Pain and Distress categories.

2.0 To Whom the Policy Applies

This policy applies to individuals using USDA-covered species under an IACUC animal use protocol. It also applies to individuals using animals supported by DoD or ONR funding. Finally, it applies to all IACUC members reviewing animal use protocols that meet the aforementioned criteria.

3.0 Policy Statement

The USDA, DoD, and ONR require that animals be assigned to a Pain and Distress category. Examples of procedures and corresponding Pain and Distress categories (i.e., categories B through E, listed from low (B) to high (E)) are included in Appendix A. If an animal or group of animals undergoes any type of procedure, the lowest category to which the animal or group of animals may be assigned is Category C. An animal or group of animals must be assigned to the highest Pain and Distress category that will apply to the animal(s) at any time while the animal is associated with the IACUC protocol, regardless of the duration of time the animal(s) is on the protocol.

4.0 Definitions

For the purpose of this policy, the terms below have the following definitions:

Distress:

An aversive state in which an animal fails to cope or adjust to various stressors with which it is presented. Distress may not induce an immediate and observable pathologic or behavioral alteration, which may make it difficult to monitor and evaluate the animal’s state when Distress is present. Both the duration and intensity of the animal’s state are important considerations when trying to prioritize attention to and treatment of animal Distress.

Pain:

A complex experience that typically results from stimuli that damage or have the potential to damage tissue; such stimuli prompt withdrawal and evasive action.

5.0 Responsibilities

All individuals to whom this policy applies are responsible for becoming familiar with and following this policy. University supervisors are responsible for promoting the understanding of this policy and for taking appropriate steps to help ensure compliance with it.

6.0 Consequences for Violating this Policy

Violation of this policy may be considered a serious event of noncompliance that is reportable to the IACUC, funding and accrediting agencies, as well as other regulatory agencies. Violations are a serious matter that may adversely affect both the ability to perform animal work and acquire funding sources.  

Failure to comply with this and related policies is subject to disciplinary action, up to and including suspension without pay, or termination of employment or association with the University, in accordance with applicable (e.g., staff, faculty, student) disciplinary procedures.
