What is cross-contamination?

Cross-contamination refers specifically to the transfer of harmful bacteria or other microorganisms from one food item to another. This is a critical concept in food safety because it can lead to foodborne illnesses if pathogens from raw or contaminated food come into contact with ready-to-eat foods. For example, using the same cutting board for raw chicken and then slicing vegetables without properly cleaning the board can result in the transfer of dangerous bacteria.

Understanding cross-contamination is vital for anyone handling food, as it underscores the importance of maintaining separate tools, surfaces, and storage for different types of foods, especially between raw and cooked items. It highlights the need for careful practices such as washing hands frequently, using distinct utensils for different foods, and implementing proper food storage techniques to prevent this contamination from occurring.
