TSE Small Animal Facility Checklist

This questionnaire is provided to you as a tool to be used in conjunction with the Containment Standards for Laboratories, Animal Facilities and Post Mortem Rooms Handling Prion Disease Agents, 1st edition 2005, as well as the Containment Standards for Veterinary Facilities (CSVF), 1st edition 1996.

TSE material:

This checklist is intended to assist TSE Small Animal Facilities in determining their compliance with the Containment Standards for Laboratories, Animal Facilities and Post Mortem Rooms Handling Prion Disease Agents.

Please provide YES, NO, N/A (not applicable) to indicate the answer to each of the criteria listed. For "NO" or "N/A" answers please contact the Biohazard Containment and Safety Unit immediately to discuss and provide a brief clarification/justification. For "YES" please provide any additional relevant information (i.e. type of biological safety cabinet, decontamination procedures used, etc.).

This questionnaire is subject to change by the Biohazard Containment and Safety (BCS) Unit at CFIA. The BCS Unit will make any changes or updates available to the regulated parties via our website, email, mail or other.
