Cross-contamination refers to the transfer of harmful bacteria or substances from one food to another. This is a critical concept in food safety, as it often occurs when raw foods, such as meats, come into contact with ready-to-eat foods, like salads or bread. Effective prevention of cross-contamination is essential in maintaining food safety and preventing foodborne illnesses. Understanding cross-contamination is important for food handlers because it highlights the need for proper hygiene practices, such as using separate cutting boards for raw meats and vegetables, washing hands thoroughly between tasks, and storing foods in a manner that prevents them from touching each other. Awareness of this practice ensures that food prepared for consumption is safe and free from harmful pathogens that can lead to illness.
