Which item is a valid physical barrier to prevent contamination of ready-to-eat foods?

• A. Gloves
• B. Nail polish
• C. Jewelry
• D. Perfume

Answer: (A)

Protecting ready-to-eat foods from contamination relies on a physical barrier that keeps hands from directly touching the food. Gloves provide that barrier, covering the hands and reducing the chance of transferring bacteria or other contaminants to the food. For gloves to work effectively, they must be used properly: hands should be washed before putting them on, gloves should be intact, changed when torn or soiled, and swapped between tasks (for example, after handling raw foods) to prevent cross-contamination. Nail polish isn’t a barrier and can chip, potentially shedding onto food. Jewelry can harbor microorganisms and may snag or fall into food, creating contamination. Perfume can contaminate food with chemicals and odors. So the item that serves as a valid physical barrier to prevent contamination is gloves.
