How should a manager prevent deliberate contamination of food by customers?

• A. Post signs about cleanliness
• B. Do not allow customers in non-public areas of the facility
• C. Install surveillance cameras
• D. Offer tasting in all areas of the facility

Answer: (B)

Keeping customers out of non-public areas is the key idea here. Limiting access to food handling and storage spaces ensures that only trained staff can handle and inspect food, reducing the opportunities for someone to tamper with products or equipment. This control is a fundamental preventive measure against deliberate contamination because it directly lowers the chances that inappropriate people or actions reach critical points in the operation.

Signs about cleanliness, while helpful for promoting good hygiene, do not prevent access to the areas where contamination could occur. Surveillance cameras can deter or help detect issues, but they don’t stop access or tampering from happening in real time. Allowing tastings in all areas of the facility would increase exposure and create more points of risk. By keeping non-public areas restricted, the facility minimizes risk at the point of food handling.
