Under what circumstance must gloves be changed when preparing a bacon shake?

Changing gloves after crushing bacon is essential to prevent cross-contamination in food preparation. Bacon can harbor bacteria, and once it is handled, any surface or food item that follows should not come into contact with those contaminants. The process of crushing bacon exposes the gloves to potential pathogens present on the meat. Therefore, changing gloves ensures that any subsequent ingredients added to the bacon shake, such as milk or toppings, do not carry over any contaminants from the bacon. This practice aligns with food safety protocols that emphasize cleanliness and preventing the spread of foodborne illnesses.

In this scenario, while handling regular milk, mixing the shake, or adding toppings might also involve food handling protocols, those activities do not pose the same level of cross-contamination risk that comes from directly handling raw bacon.
