An undeclared allergen is one of the most serious and common reasons for a food recall. A simple mistake on the ingredient label can have life-threatening consequences for a person with a severe food allergy. In 2025, the FDA has already issued numerous recalls for popular snack foods that were contaminated with undeclared allergens like peanuts, milk, and soy. These incidents highlight a persistent problem with cross-contamination and quality control in the food manufacturing industry.
