What is food cross-contamination?

Food cross-contamination refers specifically to the transfer of harmful bacteria or other microorganisms from one food item to another, often as a result of improper food handling practices. This can occur when raw foods, such as meats or eggs, come into contact with ready-to-eat foods, like fruits or salads. If the bacteria that are present on the raw food are not eliminated through cooking or if they contaminate the other food items, it can lead to foodborne illnesses.

Understanding the importance of proper food handling is crucial for maintaining food safety. For example, using separate cutting boards for raw meats and vegetables can prevent cross-contamination. This concept is critical in food service environments and home kitchens alike, as it helps protect consumers from potential food poisoning.
