All of the following are examples of food contact surfaces except?

Food contact surfaces are defined as any surfaces that come into direct contact with food during preparation, storage, or service. Understanding this definition helps clarify why freezer walls do not fall into this category.

Freezer walls are primarily structural elements that serve to maintain the refrigeration needed for food storage. They do not touch food directly and, as such, do not transfer contaminants to food items. In contrast, food prep tables, cutting boards, and dishes and utensils are all surfaces that directly come into contact with food, making them critical to maintain in a safe and sanitary condition to prevent foodborne illness.

Therefore, identifying freezer walls as the exception highlights the importance of recognizing which surfaces require regular cleaning and maintenance to ensure food safety.
