Mythbuster: Is it true that cross-contamination can occur through saliva?

February 25, 2019

FACT: Yes. Food allergens can be passed on through saliva from people (e.g. biting into/sharing an apple) and pets.

Anything that goes into the mouth could be a possible source of cross-contamination. Although small amounts of allergens may not be visible, an allergic reaction can still occur. Learn about the different types of cross contamination.

Bottom line: Cross-contamination can happen when a small amount of a food allergen gets into another food accidentally, or when it is present in saliva, on a surface or on an object. This small amount of an allergen could cause an allergic reaction.
