What type of barrier can be used to prevent contamination from germs?

The correct answer highlights that deli or wax paper is used as a barrier to prevent contamination from germs. Deli/wax paper is specifically designed to cover food items, providing a clean surface that can help minimize direct contact between food and potential contaminants in the environment. This type of paper is often used in food service settings to wrap sandwiches, pastries, or other food items, creating a physical barrier that limits exposure to airborne germs or bacteria.

In food handling and safety practices, it is crucial to use materials that are clean, food-safe, and capable of preventing contact with contaminants. While plastic wrap and paper towels can be used in certain situations, they do not serve the same primary purpose as deli/wax paper, which is specifically designed to provide a protective layer for direct food contact. This ensures better food safety and hygiene, making deli/wax paper a more appropriate choice for preventing contamination in a food service context.
