To prevent deliberate contamination of food, you should do which of the following?

Monitoring the security of products is crucial in preventing deliberate contamination of food. This strategy involves actively ensuring that all food items and ingredients are stored and handled securely, which reduces the risk of tampering or malicious actions by individuals. By keeping a close watch on who is accessing food items and maintaining strict control over food storage areas, food establishments can deter potential threats and enhance overall food safety.

Limiting employee access is also an important measure, but it is more about restricting who can handle food rather than actively monitoring the security of the products themselves. Increasing food supplies does not address contamination risks and can potentially lead to waste and storage issues. Finally, avoiding training employees is counterproductive, as well-trained staff are better equipped to recognize and prevent potential threats to food safety.

Thus, focusing on monitoring security directly targets the problem of deliberate contamination, making it a proactive and necessary approach in food safety management.
