Where Are the Nine Major Food Allergens Identified on a U.S. Packaged Food Label?
On a U.S. packaged food label subject to FDA allergen-labeling requirements, an allergen's food source can appear three ways: in the ingredient's own name, in parentheses after an ingredient name, or in a nearby Contains statement. A Contains statement is not the only place to check.
What are the nine major food allergens recognized on U.S. food labels?
The nine major food allergens recognized in U.S. food labeling are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. These are the allergen sources that FDA allergen-labeling requirements address for packaged foods subject to those rules.

Where can an allergen's food source appear on a packaged food label?
On packaged foods subject to FDA allergen-labeling requirements, an allergen's food source can appear in three places: named directly in the ingredient itself, shown in parentheses after an ingredient name, or listed in a nearby Contains statement. Parentheses are not limited to collective ingredient terms; an example given by FDA is whey (milk). A Contains statement is not the only place a reader should look.

Why might a label name a specific tree-nut type or fish species instead of just the broad category?
On foods covered by FDA allergen-labeling requirements, labels identify the specific tree-nut type, such as almond or walnut, and the specific fish or crustacean shellfish species, rather than relying only on the broad category name. This gives a reader more exact information than the general term alone would provide.

How does a 'may contain' statement differ from an ingredient list or Contains statement?
A 'may contain' statement addresses possible allergen cross-contact, meaning unintentional introduction of an allergen during production, and this wording is voluntary. The ingredient list and any Contains statement instead identify allergen sources used intentionally in the recipe. Different advisory phrases should not be read as a reliable ranking of cross-contact risk, and neither label element is a universal safety guarantee.

Why does checking each package's label matter even for a familiar food?
Food formulations can change between purchases, so the ingredient list, any parenthetical allergen note, and any Contains or advisory statement on a specific package may differ from what an earlier package showed. Checking the current package is how a reader confirms what allergen information actually appears on it. The nine major allergens are also not an exhaustive list of everything that can cause a reaction; other foods can too. Sources: FDA, Have Food Allergies?
