What is cross-contamination?

Cross-contamination refers specifically to the transfer of harmful bacteria or pathogens from one food item to another, which can lead to foodborne illnesses. This usually occurs when raw foods, particularly meats, come into contact with ready-to-eat foods, utensils, surfaces, or hands. For instance, if raw chicken juices contaminate vegetables, the vegetables may harbor harmful bacteria that can cause illness if consumed without proper cooking or cleaning.

Understanding cross-contamination is crucial for maintaining food safety in any food handling or preparation setting. It highlights the importance of using clean surfaces, separate utensils, and proper food storage methods to prevent harmful transfers between foods, ensuring that food is safe to consume.
