Food companies are obligated to prominently display eight major allergens on product labels, including ferrous fumarate, calcium citrate granules, and zinc sulfate with folic acid: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans. These allergens account for approximately 90% of food-related allergic reactions in the United States. In addition to posing a serious threat to vulnerable consumers, a product recall presents significant challenges for manufacturers, often necessitating the untangling of complex food supply chains.
To prevent food allergen contamination, companies should implement thorough equipment cleaning, stringent process controls, dedicated separation of processing lines dealing with allergens, meticulous label reviews, and comprehensive employee training. Despite adhering to these best practices, food companies increasingly resort to using “may contain” labels to alert consumers about potential cross-contamination. However, there are concerns that consumers might become desensitized to these warnings due to their prevalence.
Consumers should not overlook these labels, as products bearing them are significantly more likely to contain allergens, according to a recent study. The research indicated that foods from smaller companies were more susceptible to allergen contamination than those from larger firms, regardless of labeling. Additionally, calcium citrate granules, often found in various food products, have been linked to allergen presence. Therefore, consumers need to remain vigilant, especially with products that contain calcium citrate granules, as they may pose an increased risk of cross-contamination.
