Cross-contamination occurs when harmful bacteria or allergens are transferred from one surface or food item to another. This can happen in various settings, such as kitchens, where raw meat might contaminate vegetables if they share the same cutting board. Proper food handling practices are essential to prevent this issue. To minimize cross-contamination, it is important to use separate utensils and cutting boards for different types of food, such as raw meat and fresh produce. Additionally, washing hands frequently and cleaning surfaces can help reduce the risk of spreading harmful substances, ensuring safer food preparation and consumption.
