When conducting the facilities inspection portion of the semi-annual evaluation in compliance with both the USDA Animal Welfare Act Regulations and PHS Policy, the IACUC must include:

The correct answer involves understanding the regulatory requirements outlined in both the USDA Animal Welfare Act Regulations and the PHS Policy regarding the inspection of facilities where animals are housed and where procedures involving animals are performed. Specifically, the IACUC is required to inspect all areas housing animals for more than 12 hours, which reflects the need to ensure animal welfare and compliance with relevant regulations. The inclusion of laboratories where animal procedures are performed, as mandated, is crucial to maintain oversight over both the well-being of the animals and the ethical conduct of research activities.

Moreover, the specification that laboratories performing only non-survival surgical procedures are exempt from these inspections acknowledges the lesser impact on animal welfare in cases where no animals remain after the procedure. This exemption is important for optimizing inspection focus and resources while still satisfying the foundational principles of animal care and use.

In summary, this choice captures the essence of the regulatory framework and reflects a balanced approach to animal welfare oversight during IACUC evaluations, ensuring that essential areas of concern are reviewed while recognizing specific situations that may warrant different treatment.
