2. Understanding Allergen Labeling: What You Need To Know
The Food and Drug Administration (FDA) enforces FALCPA in the labeling of foods it regulates, which includes all foods except poultry, most meats, certain egg products, and most alcoholic beverages. Understanding how to read food labels is critical for individuals with food allergies to avoid potentially harmful ingredients. Proper labeling ensures that consumers can easily identify the presence of major food allergens in food products.
2.1. What Does FALCPA Require For Food Allergen Labeling?
FALCPA requires that food labels clearly identify the food source names of any ingredients that are one of the major food allergens or contain protein derived from a major food allergen. This ensures that consumers with allergies can easily identify and avoid these ingredients.
2.2. How Are Major Food Allergens Listed On Food Labels?
FALCPA requires that food labels identify the food source names of all major food allergens used to make the food. This requirement is met if the common or usual name of an ingredient (e.g., buttermilk) that is a major food allergen already identifies that allergen’s food source name (i.e., milk). Otherwise, the allergen’s food source name must be declared at least once on the food label in one of two ways:
- In parentheses following the name of the ingredient in the ingredient list. Examples: “lecithin (soy),” “flour (wheat),” and “whey (milk).”
- Immediately after or next to the list of ingredients in a “contains” statement. Example: “Contains Wheat, Milk, and Soy.”
2.3. What Should I Do If A Label Is Unclear About Allergen Information?
If a label is unclear about allergen information, it is best to err on the side of caution. Do not consume the product and contact the manufacturer for clarification. Additionally, you can report the unclear labeling to the FDA to help improve labeling standards for all consumers.
2.4. Are “May Contain” Statements Reliable?
“May contain” statements are voluntary and indicate that a product may have been exposed to an allergen during manufacturing. These statements are not regulated, so their reliability can vary. It is generally advisable to avoid products with “may contain” statements for allergens you are sensitive to, as the risk of cross-contamination is present.
2.5. Can I Trust Labels On Imported Foods?
Labels on imported foods must comply with U.S. labeling laws, including FALCPA. However, it’s always a good idea to carefully review the ingredient list and allergen information to ensure compliance. If you are unsure, contact the manufacturer for more information.
