Define the term "cross-contamination."

Cross-contamination refers specifically to the transfer of harmful bacteria or substances from one food item to another, often through improper food handling practices. This transfer can occur when raw foods, such as meat and poultry, come into contact with ready-to-eat foods, utensils, or surfaces that are not sanitized properly. By understanding this definition, one can appreciate the importance of food safety practices, such as using separate cutting boards for raw meat and fresh vegetables or thorough cleaning between preparing different types of food. The aim is to prevent foodborne illnesses that can arise from this type of contamination. Understanding cross-contamination is crucial for anyone involved in food preparation and service, as it directly impacts public health and the safety of meals served.
