Which item is NOT considered a physical barrier to prevent contamination?

• A. Refrigeration unit
• B. Deli/wax paper
• C. Gloves
• D. Utensils such as tongs, scoops, and spatulas

Answer: (A)

A physical barrier is something that directly blocks contaminants from coming into contact with food. A refrigeration unit isn’t a barrier in that sense; it’s an environmental control that slows or stops bacterial growth by keeping foods cold. It doesn’t physically separate food from potential contaminants.

Deli/wax paper acts as a barrier between food and surfaces or hands, reducing direct contact. Gloves also create a protective layer between the hands and food. Utensils like tongs, scoops, and spatulas keep hands away from the food and prevent cross-contact.

So the item that does not function as a physical barrier to prevent contamination is the refrigeration unit.
