Which regulation prohibits reprisal against individuals reporting violations in animal care?

The regulation that specifically prohibits reprisal against individuals who report violations in animal care is the Animal Welfare Act Regulations (AWAR). This regulation is fundamental in promoting an environment where individuals can report concerns about animal treatment without fear of retaliation. It reinforces the importance of ethical treatment and compliance within veterinary and research practices, ensuring a safe reporting mechanism for whistleblowers.

The AWAR establishes guidelines meant to protect the welfare of animals in research and testing, emphasizing the responsibility of institutions to encourage reporting any concerns related to animal care and ensure individuals are not penalized or intimidated for doing so. This protective measure is essential for fostering transparency and accountability in research practices and upholding high ethical standards in animal care.

The other options—PHS Policy, the Nuremberg Code, and DoD Directives—do touch on various aspects of ethical treatment and oversight in research involving animals, but they do not specifically address the issue of protecting individuals from reprisal when reporting violations.
