What action must a food handler take if diagnosed with a contagious illness?

When a food handler is diagnosed with a contagious illness, it is essential for them to prioritize public health and food safety. Reporting the condition to management and being excluded from work until cleared is crucial to prevent the potential spread of the illness to customers and coworkers, which could lead to widespread health risks.

This action not only protects the safety of food served to customers but also complies with health regulations and guidelines that mandate food handlers to report certain illnesses. Exclusion from work until the food handler is deemed fit to return reduces the risk of contamination in the food preparation area and ensures a safer environment for all.

The other options may create situations where the risk of spreading illness increases or where proper protocols are not followed, putting public health at risk. Ensuring that the food handler is cleared by a medical professional before returning to work is a responsible course of action that aligns with food safety management principles.
