YSK: Most bread manufacturers are now putting sesame into their products Why YSK: A federal law requiring that sesame be listed as an allergen on food labels is having unintended consequences — increasing the number of products with the ingredient. Food industry experts say the most requirements are so stringent that many manufacturers, especially bakers, find it simpler and less expensive to add sesame to a product — and to label it — than to try to keep it away from other foods or equipment with sesame… Several companies — including national restaurant chains like Olive Garden, Wendy’s and Chick-fil-A and bread makers that stock grocery shelves and serve schools — are adding sesame to products that didn’t have it before. That’s frustrating and scary for parents like Kristy Fitzgerald of Crookston, Minnesota. She learned last spring that Pan-O-Gold Baking Co., which supplies breads to schools, health centers and grocery stores across the Midwest, was adding small amounts of sesame to its products, including those served at her daughter’s school. Six-year-old Audrey, in the meantime, has outgrown her allergy to sesame.
