Some Bakeries Answered a Labeling Law by Adding More Allergen

On January 1, 2023, sesame became the ninth major food allergen in the United States. The FASTER Act, signed April 23, 2021, amended the Federal Food, Drug, and Cosmetic Act so that sesame sits alongside milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans. The intent was straightforward: people with sesame allergy — more than 1.6 million Americans, according to FARE research — would finally see it declared on labels. Then something strange happened. Rather than cleaning their lines to prevent sesame cross-contact, some bakeries began adding small amounts of sesame flour to products that had never contained it. The logic was cold: a product that intentionally contains sesame only needs a label, while a sesame-free product needs verified cleaning. FDA’s response was blunt. Adding sesame and declaring it may satisfy the label line, but it does nothing for the sesame-allergic consumer the law was written to protect.

What the Law Changed on Your Label

Sesame must now be declared in plain language whenever it is an ingredient, and the old hiding places are closed. You can no longer tuck it under “spices” or “natural flavor.” Ingredients derived from sesame — tahini is the classic example, and sesame oil counts too — must make the sesame content clear to the reader. If the flour blend in your formula contains sesame, the finished label declares it. FDA’s position is that the declaration has to be understandable to an ordinary consumer, which means the word “sesame” or “contains sesame” in the ingredient statement, not a technical synonym. Labels printed before the effective date got enforcement discretion for a transition period, but that window is long closed. Every label you approve today with an undeclared sesame ingredient is a misbranding violation waiting for a consumer reaction to reveal it. Check the label against the formula, not against last year’s artwork.

Your Food Safety Plan Now Has Nine Allergens

The labeling change got the headlines, but the quieter half of the FASTER Act lives in your food safety plan. Under 21 CFR Part 117, allergen controls are preventive controls, and sesame now belongs in every hazard analysis, every allergen control procedure, and every sanitation verification where the other eight appear. That means updating the allergen map of your facility: which lines run sesame, which ingredients contain it, where shared equipment creates cross-contact risk. Supplier verification has to ask the sesame question explicitly — do your ingredient suppliers handle sesame in their facilities, and what do they do to prevent it from reaching your ingredients? Employee training needs the same update, because a sanitation crew that has memorized eight allergens will walk past the ninth. The plan update is not a find-and-replace of the word “eight” with “nine.” It is a fresh walk through the building with sesame in mind.

The Sanitation Standard FDA Actually Judges You Against

FDA doesn’t prescribe one cleaning method for allergens. It judges whether your method works. For sesame, that judgment usually turns on four things: scheduling, separation, cleaning validation, and changeover discipline. Scheduling means running sesame-containing products last in the production sequence where possible, so the deepest clean happens before the allergen-free run. Separation means dedicated equipment, utensils, and storage for sesame where volume justifies it. Cleaning validation means proving the method removes sesame protein — visual inspection alone won’t carry the argument, so validated swabs for protein or sesame-specific residue have a place in the program. Changeover discipline means the procedure is written, timed, and followed the same way on a Tuesday night as during an audit. Bakeries face a genuine complication here: dry environments limit water-based cleaning, which makes sesame seed and flour removal harder. That difficulty is a reason to design a better dry-cleaning procedure, not a reason to skip it.

The “Just Add Sesame” Shortcut, Examined Honestly

Let’s steelman the bakery position for a moment, because the shortcut didn’t come from nowhere. Validating allergen cleaning costs money: swabs, lab time, downtime between runs, reformulated schedules. For a high-volume bun line running on thin margins, intentional addition plus a label line looked like the cheaper compliance path. It also looked, to some, like the safer legal path — a declared allergen can’t trigger an undeclared-allergen recall. Here’s where the argument collapses. The Center for Science in the Public Interest petitioned FDA over the practice, arguing that manufacturers who identify a cross-contact risk have a responsibility to control it, not to normalize it. FDA’s own framing agrees in substance: the law’s purpose is protecting sesame-allergic consumers, and shrinking their safe food choices achieves the opposite. A customer who safely ate your rolls for years now faces anaphylaxis risk from the same product, and your label technically complies. Legally defensible and publicly indefensible is a terrible place to run a food brand from.

What “Adequate” Sesame Cleaning Looks Like in Practice

Start with the allergen map: mark every point where sesame enters, travels, and could linger — ingredient staging, scaling, mixers, conveyors, pans, cooling racks, packaging. Write the cleaning procedure for each point specifically for sesame, with dry-cleaning methods where water is restricted: vacuuming with HEPA filtration, scraping, brushing, and validated wipe-downs. Validate once with sesame-specific testing so you have evidence the procedure works, then verify on a schedule with faster tools like protein swabs. Control rework ruthlessly — rework containing sesame can only re-enter sesame-containing products, and the tracking has to prove it. Train the crew on why sesame behaves differently: tiny seeds lodge in equipment crevices and survive visual inspection, so the standard is removal, not tidiness. Document every validated clean. When an auditor or an FDA investigator asks how you control sesame, the answer should be a procedure, a validation record, and a verification log — not a shrug and a label.

Start With One Line, One Product, This Month

Pick your highest-volume product line and run a complete sesame gap review on it before anything else. Confirm the formula against the label, word for word. Walk the line with the allergen map and mark every sesame touchpoint. Check that the cleaning procedure names sesame explicitly and that the crew can describe it without reading the binder. Call the suppliers of that line’s ingredients and get their sesame handling in writing. Fix what you find on this one line, then roll the method across the plant. Sesame compliance isn’t a project with a finish date; it’s the ninth permanent resident in your allergen program. The bakeries that added sesame instead of managing it bought a short-term convenience at the price of consumer trust. Build the cleaning program, declare what’s truly in the food, and let the label tell the truth.
