Which publication provides the species-specific environmental standards used in IACUC oversight?

• A. AAALAC Accreditation Standards.
• B. The Guide for the Care and Use of Laboratory Animals.
• C. The Federal Register.
• D. The Animal Welfare Act regulations.

Answer: (B)

Species-specific environmental standards used in IACUC oversight come from The Guide for the Care and Use of Laboratory Animals. This publication provides detailed, species-tailored recommendations on housing, husbandry, and environmental conditions—like cage size, temperature, humidity, lighting, enrichment, and social housing—that committees rely on when evaluating and approving animal care plans. While laws and regulations establish the legal framework (Animal Welfare Act and its regulations) and accreditation programs exist (AAALAC), The Guide serves as the practical benchmark for day-to-day care and compliance in IACUC oversight.
