When should gloves be changed while handling food?

The choice indicating that gloves should be changed when switching tasks, after handling raw food, or if they become contaminated is correct because it prioritizes food safety and hygiene in food service operations.

Changing gloves regularly helps to prevent cross-contamination, which is a significant concern in food handling. For instance, switching tasks, such as moving from preparing raw meat to assembling a salad, requires a glove change to avoid transferring harmful pathogens from one food type to another. Additionally, if gloves become contaminated, it is crucial to remove and change them to maintain a safe environment for food preparation.

The other options suggest practices that are less effective in ensuring food safety. For example, changing gloves only after a set period or solely after handling cooked food overlooks critical moments when contamination could occur. This can lead to unsafe food practices that can put consumers at risk of foodborne illnesses. Therefore, recognizing the need to change gloves based on specific circumstances of food handling is essential for complying with health and safety regulations in food service.
