What is the main reason for sanitizing food-contact surfaces?

Sanitizing food-contact surfaces is primarily aimed at preventing cross-contamination. Food-contact surfaces are those that come into direct contact with food, and if they are not properly sanitized, harmful pathogens can transfer from these surfaces to the food. This transfer can occur through residue from raw food, spills, or after preparing contaminated food.

By sanitizing these surfaces, the goal is to eliminate harmful microorganisms that can cause foodborne illnesses. Proper sanitation reduces the risk of these pathogens surviving and subsequently contaminating the food that will be consumed, thus protecting public health.

While other actions like removing dirt and improving appearance may be secondary benefits of sanitizing, they do not address the critical issue of food safety that sanitizing aims to tackle. Enhancing flavor is not related to sanitation practices, as sanitation is focused on safety rather than sensory attributes of food.
