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)

Physical barriers stop contamination by blocking direct contact between food and potential sources of contamination. Gloves, utensils like tongs or scoops, and deli or wax paper all serve as shields between hands, surfaces, and food, helping prevent transfer of bacteria or other contaminants.

A refrigeration unit, on the other hand, is a control method that slows or halts the growth of microorganisms by keeping foods cold. It doesn’t physically prevent contamination from touching the food; it just slows any growth that could occur. That’s why it’s not considered a physical barrier.

So, the refrigeration unit is the item that is not a physical barrier to prevent contamination.
