What is cross-contact in the context of food allergies?

Cross-contact refers specifically to the unintentional transfer of allergens from one food item to another, often through shared surfaces, utensils, or cooking equipment. This can occur during food preparation, cooking, or serving, posing a significant risk to individuals with food allergies. For example, if a knife used to cut a food containing an allergen is then used to cut another food that does not contain that allergen, the second food can become contaminated.

Understanding cross-contact is critical for allergy management, as even trace amounts of an allergen can trigger serious allergic reactions in sensitive individuals. This highlights the importance of maintaining strict food handling and preparation practices to prevent cross-contact, such as using separate utensils and surfaces for allergen-free foods.
