Assistant Laboratory Animal Technician (ALAT) Practice Exam

What should be monitored regularly to ensure the welfare of laboratory animals?

1. Food supply

2. Pest control

3. Environmental conditions

4. Cage cleanliness

The correct answer is: Environmental conditions

Monitoring environmental conditions is crucial for ensuring the welfare of laboratory animals because these conditions directly impact their health and well-being. Factors such as temperature, humidity, light cycles, and air quality play significant roles in the physiological and psychological status of the animals. For instance, extreme temperatures or poor ventilation can cause stress or even illness in the animals. Ensuring that environmental conditions are optimal allows for better outcomes in research and promotes a humane approach to animal care. The other aspects, while important, may not directly encompass the overall welfare framework as comprehensively as environmental conditions do. Food supply and cage cleanliness are essential for health, pest control mitigates risks of disease, but without a proper environmental setup, those measures alone may not suffice in safeguarding the animals' welfare. Thus, consistent monitoring of environmental conditions ensures that all other factors align for the best possible living conditions for laboratory animals.
