When a server touches the food-contact surface of a water glass while setting tables, what issue arises?

The correct answer is cross-contamination, which occurs when harmful microorganisms or allergens are unintentionally transferred from one surface or food item to another. When a server touches the food-contact surface of a water glass with ungloved hands or after handling raw food, they can introduce bacteria or pathogens that may be present on their hands. This poses a risk to the consumer, as these pathogens can lead to foodborne illnesses if ingested.

In the context of a food service establishment, maintaining clean and sanitized food-contact surfaces is crucial to prevent cross-contamination. Proper training emphasizes the importance of hand hygiene and minimizing contact with surfaces that will be in contact with food or drinks. This includes using gloves when necessary and ensuring that servers are aware of the need to keep their hands and other potential contaminants away from food-contact surfaces.
