Undeclared Allergen
A major food allergen present in a product but not listed on the label, the leading cause of food recalls in the U.S.
What It Means
An undeclared allergen is a major food allergen that is present in a food product but not identified on the product label. Undeclared allergens are the single most common reason for food recalls in the United States, accounting for roughly 40 to 50 percent of all FDA food recalls in recent years. Under FALCPA, food manufacturers are required to clearly declare the presence of nine major allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. When a product contains one of these allergens but the label fails to disclose it, the product is considered misbranded and subject to recall. Undeclared allergens can end up in products through several pathways: cross-contamination on shared production lines, incorrect labels applied to products, formulation changes where new allergen-containing ingredients are added without updating the label, supplier errors where an ingredient contains an allergen not disclosed to the manufacturer, and rework of products containing allergens into allergen-free product lines. For the estimated 32 million Americans with food allergies, undeclared allergens pose a serious and potentially life-threatening risk. Accidental exposure to an allergen can trigger reactions ranging from mild hives and digestive discomfort to severe anaphylaxis requiring emergency medical treatment. Most undeclared allergen recalls are classified as Class I due to the potential for serious harm or death.
