What action should the IACUC take if an investigator mistakenly euthanizes animals using a method not approved in the protocol?

Retraining the investigator and staff is an appropriate course of action in this scenario because it addresses the root cause of the error — a misunderstanding or lack of knowledge regarding the approved euthanasia methods outlined in the protocol. This approach emphasizes the importance of education and reinforcement of protocols to prevent future incidents. Through retraining, the IACUC can ensure that all personnel involved in animal care and use are properly informed about the procedures, reducing the likelihood of similar mistakes occurring in the future.

Additionally, this action supports a culture of compliance and responsibility within the research environment, encouraging investigators and staff to adhere strictly to established protocols. It’s also a corrective measure that can foster a learning environment rather than one that solely focuses on punitive actions. By focusing on retraining, the IACUC is actively working towards improving both individual and institutional practices concerning animal welfare.
