Last week, FDA issued a draft guidance that outlines the agency’s proposed approach for evaluating the public health importance of food allergens other than the eight major food allergens identified by US law, which are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans. By law, those allergens must be listed separately from other ingredients on food labels. As discussed in a prior blog post, sesame is set to become the ninth major food allergen on January 1, 2023.
