What is a recommended method for screening the health of incoming animals?

The recommended method for screening the health of incoming animals is to use a health checklist for each animal. This approach allows for a thorough evaluation of various health parameters, including physical condition, signs of disease, and vaccination status. By employing a health checklist, laboratory personnel can systematically assess each animal and identify any potential health issues before they integrate into the main housing facility.

Isolating animals in separate cages can be a component of biosecurity and helps prevent disease transmission, but it does not provide a comprehensive health assessment. Similarly, requesting extra animals from the vendor does not ensure that those additional animals are healthy or that the initial batch is adequately screened for health concerns. Conducting health screenings after arrival may result in unnecessary exposure to disease and complicate management practices; proactive health checks prior to their entry are more effective for maintaining the overall health of the laboratory environment.
