Who is responsible for ensuring the welfare of animals used in research?

• A. The Institutional Review Board (IRB)
• B. The principal investigator
• C. The IACUC
• D. The veterinarian on staff

Answer: (C)

The correct answer highlights the role of the Institutional Animal Care and Use Committee (IACUC) in overseeing the welfare of animals used in research. The IACUC is a mandated body that ensures compliance with federal regulations and ethical standards concerning animal research. It reviews research protocols, monitors animal care practices, and ensures that researchers adhere to established guidelines designed to enhance animal welfare.

While the principal investigator plays a significant role in the daily management of the research project and is responsible for ensuring that their work meets ethical standards, the ultimate oversight and approval of animal care policies and practices fall to the IACUC. This committee’s responsibility is to ensure that all aspects of animal use are ethically justified and that the welfare of the animals is prioritized throughout the research process.

The veterinarian on staff contributes to animal welfare by providing veterinary care and ensuring the health of the animals, but their role is typically part of the larger framework of oversight provided by the IACUC. The Institutional Review Board (IRB), while important for human subject research, does not have authority over animal welfare issues.

Thus, the IACUC’s central role in evaluating, approving, and monitoring research activities related to animal use makes it the primary body responsible for the welfare of animals in research settings.
