Answer :
Final answer:
Cross-contamination is the transfer of pathogens from one food or surface to another, commonly occurring when raw foods like meat come into contact with ready-to-eat foods without adequate cleaning. It is a leading cause of foodborne diseases and can be prevented by following proper food handling and sanitation practices.
Explanation:
Cross-contamination occurs when pathogens are transferred from one surface or food to another. This typically happens when raw foods that contain bacteria, such as Salmonella, come into contact with ready-to-eat foods without proper sanitation measures in between. Using the same cutting board, knife, or countertop for preparing raw poultry, meat, or eggs, and then using it for preparing foods like fruits, vegetables, or bread without cleaning, can lead to contamination of food by microbes.
Foodborne diseases can arise from improper handling, preparation, or storage of food, with cross-contamination being one of the main causes. Ensuring food safety requires not only diligence in home kitchens but also adherence to standards by government agencies like the Food and Drug Administration. Key practices to prevent foodborne illness include maintaining proper hygiene, avoiding cross-contamination, and controlling food temperatures.
