Can chewing gum contain allergenic substances?

Chewing gum does not typically contain significant amounts of the eight major allergens that are known to cause most allergic reactions.

However, because chewing gum is a food, its labeling is governed by national labeling requirements, including requirements relating to allergen disclosure. Sensitive consumers with specific concerns about the ingredients contained in chewing gum should review the label and may wish to consult with the individual manufacturers.
