Allergen labeling refers to the rules that require certain allergens to be clearly listed on packaged food products. In the United States, federal law (named FALCPA) requires manufacturers to clearly disclose the Top 9 allergens. These include milk, eggs, peanuts, tree nuts, soy, wheat, fish, shellfish, and sesame.
If a product contains one of these allergens, it must be identified in plain language. This is usually done in one of two ways. The allergen may be listed in parentheses next to the ingredient, such as:
- whey (milk)
- or it may appear in a separate “Contains” statement under the ingredient list.
These labeling rules are designed to make it easier and safer for families managing food allergies. Instead of decoding scientific ingredient names, you can quickly scan for the major allergens.
It is important to remember that allergen labeling laws apply to packaged foods regulated by the US FDA. Restaurant foods, airline foods, bakery items, and some specialty products may not follow the same rules. Always double check and never assume.
Reading labels every single time you buy a product is ALWAYS essential. Ingredients and manufacturing processes can change without warning, even on products you’ve had in the past.
