According to federal guidelines, what is the minimum number of IACUC members required?

• A. Three members
• B. Five members
• C. Seven members
• D. Ten members

Answer: (B)

The minimum number of IACUC (Institutional Animal Care and Use Committee) members required, according to federal guidelines, is five. This is established to ensure that the committee has a sufficient diversity of perspectives and expertise, which is imperative for the ethical review of animal research protocols. The five-member minimum includes individuals with varying backgrounds, including at least one member who is knowledgeable in the areas of animal research and one who is not affiliated with the institution, which ensures an objective viewpoint in the deliberations.

Moreover, having a five-member committee helps to facilitate a thorough discussion of protocols involving animal use and welfare, providing checks and balances in the decision-making process. This structure is designed to promote ethical animal research and compliance with regulations, ensuring that research proposals are subject to scrutiny from multiple angles, thus protecting animal welfare.
