Cross-Contact vs Cross-Contamination

Though cross-contact and cross-contamination sound similar, they are very different, especially when it comes to food allergies. Knowing the difference is crucial to understanding what you should protect yourself from.

Cross-Contact

Cross-contact happens when allergens are transferred from one object to another, usually unintentionally. Many people used to know this as cross-contamination, which is part of the problem. Since proteins cause food allergens, they cannot be removed by cooking, so even a small amount could trigger a serious allergic reaction in someone with a food allergy. 

A couple of examples of cross-contact include using the same cutlery to prepare foods (with and without allergens) or sharing cooking equipment without properly cleaning it.

Preventing cross-contact requires using separate equipment, washing hands, and carefully handling allergen-containing foods. These sanitary practices contribute to a safer dining experience for all.

Cross-Contamination

Cross-contamination is when biological pathogens (viruses, bacteria, fungi, parasites) are accidentally present in foods. The effects of cross-contamination, while still potentially dangerous, are significantly lessened when food is cooked, which is a main differentiator from cross-contact.

Regardless, similar steps must be taken to reduce these risks in the first place. It mainly boils down to keeping things separate and sanitized and reducing contact. This includes using sanitization agents on surfaces that have touched foods associated with certain diseases, such as eggs (Salmonella) and ground beef (E. coli).

As long as thorough safety and sanitization practices are implemented when preparing foods, the risk of cross-contact and cross-contamination is significantly decreased, and you should be able to enjoy your meal.
