Sesame food allergy: FDA adds ingredient to major food allergen list

Sesame has joined the U.S. Food and Drug Administration's list of major food allergens and will soon be added to labels of packaged food to protect consumers.

The eight initial food allergens that cause the majority of serious food-related allergic reactions -- all established in 2004 -- include milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat and soybeans, according to the FDA. Sesame is the ninth food to be added to the list.

As of Jan. 1, 2023, the agency stated that sesame is required to be labeled as an allergen on food packages, including dietary supplements.

"Even though the requirement that sesame be listed on the label as an allergen is in effect -- you still may find food products for sale that don't list sesame as an allergen on the label," the FDA stated. "The law establishing this sesame labeling does not require food products that were already on their way to the store or in stock before 2023 to list sesame as an allergen on the label."

During this transition period, consumers should note that food products on store shelves that were produced prior to Jan. 1 will not be removed or relabeled.

"Because some packaged foods can have a long shelf life, it's hard to say when pre-2023 stock will be replaced with food products carrying the required labels," the FDA statement continued. "So, proceed with caution during this transition period."

The FDA also said that this serves as an important reminder for shoppers to always check labels on food products each time, since labels and ingredients can change, even if it's a staple you've eaten before without an allergic reaction.

With the new labeling requirements, the name of the food source of a major allergen must appear either in parentheses following the name of the ingredient, such as "natural flavor (sesame)," or immediately next to the list of ingredients, such as "contains sesame."

"Sesame has always been required to be listed in the ingredient statement if it was an added ingredient, with a few exceptions," the FDA explained. "Now that sesame is a major food allergen, the FDA expects that it be specifically listed as sesame on the label if it's part of another ingredient, like 'natural flavor,' or 'spice mix.'"

The new sesame labeling requirements apply to packaged foods, but allergen labeling for foods that aren't packaged, like fresh bagels in a grocery bin, may vary. For customers with allergy concerns, the FDA suggests asking store employees for food allergen information.

The change was made through the Food Allergy Safety, Treatment, Education, and Research (FASTER) Act, a federal law passed in 2021. The other eight major food allergens were defined through a federal law passed in 2004.
