How can cross-contamination occur?

Cross-contamination occurs when pathogens, including bacteria and viruses, are transferred from one surface or food item to another. This often happens when raw food, such as meat, poultry, or seafood, contaminates cooked food, ready-to-eat foods, or clean surfaces. For instance, if you use the same cutting board for raw chicken and then chop vegetables for a salad without cleaning the board in between, bacteria from the chicken can spread to the vegetables, posing a risk of foodborne illness.

Understanding this concept emphasizes the importance of proper food handling techniques. Keeping raw and cooked foods separate, using clean utensils, and maintaining a hygienic kitchen environment are crucial steps in preventing cross-contamination. This is especially important for food handlers to ensure the safety of the food served and to protect consumers from potential health risks.
