The presence of foreign objects, such as small pieces of plastic or metal, is one of the leading causes of recalls in the U.S., according to the regulatory compliance company Trace One. Its research revealed that foreign objects accounted for 11.6 percent of all recalls issued between 2020 and 2024.

The most common cause of food recalls is the presence of unintended allergens and contamination with harmful bacteria or viruses.

Allergen contamination was responsible for almost 40 percent of recalls issued by the FDA and Food Safety and Inspection Service (FSIS) between 2020 and 2024, according to Trace One.

The nine major allergens—milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame—are all required by law to be clearly marked on all products to help people avoid foods that could trigger serious allergic reactions.

Bacterial contamination, including by salmonella, E. coli and listeria, is the second-most common reason for recalls, accounting for 21 percent of withdrawals.

“Foodborne diseases can be quite serious––even deadly,” Lisa R. Robinson, vice president of global food safety and public health at Ecolab, told Newsweek.

“The challenge is that the pathogens responsible for foodborne illness are all naturally occurring. Salmonella and E. coli, for example, can be found in the gut biome of chickens and cattle. Cronobacter and listeria are even more present––they can be found in soil and fields, so they’re easily tracked from one environment to another.”
