When reporting an IACUC suspension of an animal activity, the IACUC should:

The requirement to report an IACUC suspension of an animal activity to regulatory authorities as soon as possible underscores the commitment to transparency and compliance with ethical standards. Prompt notification allows regulatory bodies to assess the situation in a timely manner, ensuring that animal welfare is prioritized and any potential issues are addressed swiftly. This action demonstrates the institution's dedication to upholding animal care standards and regulatory compliance while enabling the regulatory authority to take the necessary measures if further investigation or action is warranted.

The other options do not align with best practices for reporting in IACUC contexts. Limiting disclosure to minimize institutional embarrassment contradicts the principles of transparency and the responsibility to ensure animal welfare. Delaying notification for up to one year or requiring a minimum waiting period of three months before reporting could hinder timely investigations and responses, potentially allowing conditions that violate standards to persist unaddressed. Thus, immediate communication is essential for maintaining compliance and integrity within animal research practices.
