Which statement correctly defines cross-contamination versus cross-contact?

• A. Cross-contamination is allergen transfer; cross-contact is bacterial transfer.
• B. Cross-contamination is the transfer of bacteria between foods or surfaces; cross-contact is the transfer of an allergen to a food.
• C. Both terms describe the same process.
• D. Cross-contact occurs only with gluten.

Answer: (B)

Cross-contamination involves the transfer of bacteria from one food or surface to another, such as using the same cutting board or knife for raw chicken and then for produce without proper cleaning. Cross-contact is about allergens, where an allergen is transferred to a food—through shared utensils, equipment, or hands—making that food unsafe for someone with a specific allergy, even if no bacteria are present. The key distinction is the type of transfer: bacteria versus an allergen. This is why the statement that cross-contamination is bacterial transfer and cross-contact is allergen transfer is the correct one.
