Which of the following statements about ongoing welfare oversight is most accurate?

• A. Oversight ends after initial protocol approval.
• B. Welfare oversight is optional and only necessary for select species.
• C. Welfare oversight is handled solely by the veterinarian, not the IACUC.
• D. It includes ongoing welfare assessment, veterinary oversight, and reporting of deviations throughout the study.

Answer: (D)

Ongoing welfare oversight keeps animal welfare active from the moment a study begins through its completion. This means the IACUC and the attending veterinarian continuously monitor the animals, assess their condition, and ensure appropriate care and procedures are followed throughout the study. They watch for signs of pain or distress, enforce humane endpoints, and ensure pain management and welfare standards are maintained as the work progresses. If anything deviates from the approved plan or an adverse event occurs, it must be reported promptly and addressed, potentially leading to protocol modifications or changes in how the study is conducted. This continuous oversight reflects that welfare protection is an ongoing process, not a one-time check at protocol approval. The responsibility is shared among the IACUC, the veterinarian, and the research team, rather than being the sole duty of the veterinarian, and it applies to all regulated species, not just a subset.
