Why is there a public health justification embedded in lab animal regulations, and which policy specifically addresses this?

• A. To promote animal welfare only; AWA
• B. To protect human health and safety and ensure scientific integrity; PHS Policy.
• C. To ensure availability of animals
• D. To reduce cost of research

Answer: (B)

Public health concerns drive lab animal regulations because humane care and proper handling of animals directly impact human safety and the reliability of scientific results. When animals are stressed, in pain, or not adequately cared for, experimental data can be biased or unusable, and researchers and staff may face greater occupational risks. The policy that specifically addresses this public health justification is the Public Health Service Policy on Humane Care and Use of Laboratory Animals. It applies to institutions receiving PHS funding and requires IACUC oversight, adherence to the Guide for the Care and Use of Laboratory Animals, and ongoing compliance to minimize pain and distress and to use alternatives when possible. This policy links humane animal care to protecting public health and ensuring scientifically valid, credible research.
