Can You Claim Gluten-Free on Cottage Food Labels?

The FDA's final rule on gluten-free labeling (effective August 2014) defines "gluten-free" as meaning the food does not contain wheat, rye, barley, or crossbreeds of these grains; does not contain an ingredient derived from these grains that has not been processed to remove gluten; and does not contain an ingredient derived from these grains that has been processed to remove gluten if its use results in more than 20 ppm of gluten in the food. All three conditions must be met simultaneously.

The 20 ppm threshold is a maximum — not a target. A food claiming to be gluten-free must contain unavoidably less than 20 ppm of gluten in the finished product. The rule applies equally to products that inherently contain no gluten (like plain fruit jam) and to products formulated to be gluten-free (like a rice flour cookie). If you make the claim, you're subject to the standard regardless of your ingredients.

Importantly, the FDA rule does not require pre-market testing or certification before a manufacturer can make a gluten-free claim. The standard is based on manufacturer responsibility and reasonable assurance that the product meets the threshold. However, this shifts the compliance burden entirely onto you as the producer. If a consumer with celiac disease has a reaction to your labeled gluten-free product, you bear the responsibility for demonstrating that your product actually met the standard. For a cottage food producer operating from a home kitchen, that demonstration may be impossible.

Some states have adopted the FDA standard by reference in their cottage food laws, while others have additional or separate requirements. A few states specifically address gluten-free claims for cottage food operations, sometimes requiring disclosure that the product was made in a home kitchen that is not inspected. Always check your specific state's cottage food rules for any language about special dietary claims.

Cross-contact — the transfer of a food allergen or gluten from one food to another — is the central challenge for home-based gluten-free production. Unlike a dedicated gluten-free bakery that has never allowed wheat flour through its doors, a typical home kitchen is a shared environment. Even if you personally bake gluten-free, other household members may cook with wheat, use shared toasters, or store wheat flour in the same cabinets as your gluten-free ingredients.

Wheat flour is particularly problematic because it becomes airborne during baking and measuring. Flour particles can remain suspended in the air for two hours or more and settle on countertops, in bowls, in stand mixer bowls, on baking pans, and in the grooves of measuring cups. Standard cleaning — wiping down a counter — does not remove all flour residue. Flour that has settled into the pores of wooden surfaces, cutting boards, or older silicone equipment may never be fully removed by household washing.

Shared equipment is another major source of cross-contact. A stand mixer bowl, a rolling pin, a colander, a sifter — any of these that have been used with gluten-containing ingredients pose a risk. Some shared items, like colanders and sifters, are nearly impossible to fully decontaminate and should never be used for gluten-free production if they have previously contacted wheat flour. Wooden spoons and cutting boards are in the same category.

The 20 ppm threshold is low enough that even trace contamination from shared equipment or airborne flour can push a product over the limit. Testing a finished product is the only way to know with certainty whether it meets the standard, and food testing labs that measure gluten levels charge fees that may not be economically viable for small-batch cottage food production. This combination of factors — shared environment, shared equipment, and the cost of verification — is why most food safety experts advise against making a formal gluten-free claim from a standard home kitchen.

Because the FDA's gluten-free standard is a finished-product standard based on a 20 ppm threshold, some cottage food producers consider using alternative language that is technically accurate without making a regulated claim. The most common alternative is "made without gluten-containing ingredients" or "made with no gluten-containing ingredients." This language communicates that the recipe does not call for wheat, rye, or barley — which is truthful — without asserting that the finished product meets the 20 ppm standard.

However, this alternative language comes with its own obligations. Under FDA regulations and FTC guidelines, any claim on a food label must be truthful and not misleading. If you label a product "made without gluten-containing ingredients" but your kitchen regularly uses wheat flour and your equipment is shared, the claim may still be considered misleading to celiac consumers who interpret "made without" as meaningfully safer than conventional products. Context matters: if your label gives the impression the product is safe for celiac disease when it may not be, that impression itself is problematic.

A more conservative approach is to include a cross-contact disclosure. Something like "Made in a home kitchen that also processes wheat" tells gluten-sensitive customers what they need to know to make an informed decision, without making a claim you cannot substantiate. Some states actually require this kind of disclosure for all cottage food products regardless of gluten content, as part of their general cottage food labeling requirements.

The most defensible position for a cottage food producer in a standard home kitchen is to avoid making any gluten-related claim and to answer direct customer questions honestly. If a customer at a farmers market asks if a product is gluten-free, explain that it's made without gluten-containing ingredients in your home kitchen but that you cannot guarantee it meets the FDA gluten-free standard due to shared kitchen environment. This transparency builds trust and protects you legally far better than a label claim you cannot substantiate.

If you are serious about producing gluten-free cottage food products, the path to doing so responsibly requires dedicated equipment, controlled storage, and a disciplined approach to kitchen management. "Dedicated" means equipment that has never been used with gluten-containing ingredients and is stored separately to prevent cross-contact. This includes mixing bowls, beaters, spatulas, baking pans, measuring cups and spoons, rolling pins, and any other utensil that contacts your food.

Equipment that has previously been used with wheat flour cannot be fully decontaminated by household washing, even in a dishwasher. Research on the subject consistently shows that porous surfaces, grooves, and worn finishes in older cookware can harbor gluten that washing cannot remove. If you want to produce genuinely gluten-free products, start with new equipment — or equipment that you can document has never contacted gluten — and keep it strictly separate from all other kitchen tools.

Storage is equally important. Gluten-free ingredients must be stored away from wheat flour and other gluten-containing products. Bulk flour containers should not be stored near open gluten-free ingredient containers. Even commercially sealed gluten-free ingredients should be stored separately, as cross-contamination can occur when multiple bags and containers are opened and closed in the same environment.

Consider the timing and sequence of your baking. If you bake conventional products with wheat flour in your kitchen, even producing your gluten-free products on a different day is not sufficient unless you've done a thorough deep-clean of all surfaces and airborne flour has had time to fully settle and be removed. Some cottage food producers designate separate baking days and deep-clean between sessions, but this level of control is difficult to maintain consistently and even harder to document in a way that would satisfy a regulatory inquiry.

Whatever gluten-related language you choose — or choose not to use — on your cottage food label, customer education is an essential complement. At farmers markets, craft fairs, and online marketplaces, you can use your product descriptions and direct conversations to give customers the context they need. A brief note that says "This recipe uses no wheat, rye, or barley, but is produced in a home kitchen that handles gluten-containing products" is honest, informative, and protective of your liability.

If you sell online for local pickup, your product listing is an opportunity to provide more detail than a small label can hold. Use your product description to explain your baking environment, the steps you take to minimize cross-contact, and whom the product is appropriate for. Celiac disease and non-celiac gluten sensitivity are different conditions with different tolerance thresholds, and helping customers understand the distinction allows them to make informed decisions rather than relying on a claim you cannot fully substantiate.

For cottage food producers who want to serve the celiac community responsibly and have the means to do so, some states permit cottage food operations to produce under specific exemptions that require inspection or registration. An inspected, registered facility — even a home kitchen — may be held to a higher standard that supports making a formal gluten-free claim. Investigate whether your state offers this pathway if it's something you want to pursue.
