What does cross-contact mean for allergies?

• A. Allergens becoming airborne and causing contamination
• B. Cross-contact only occurs in shared ovens
• C. Contact with allergens through utensils, surfaces, or containers that contaminates food.
• D. Allergens are neutralized by washing hands

Answer: (C)

Cross-contact means an allergen is unintentionally transferred onto food through contact with contaminated utensils, surfaces, or containers, so the food ends up carrying an allergen it shouldn’t have. This explains why careful separation of ingredients, using clean tools, and dedicated equipment matter—tiny amounts stuck to cutting boards, knives, countertops, or mixing bowls can still trigger reactions. It’s not about airborne particles or about a single place like an oven; it’s about any time a contaminated surface or tool touches food. Washing hands helps, but it doesn’t guarantee complete removal of every allergen from all surfaces or tools, so thorough cleaning and separate prep practices are essential.
