Cottage food laws in every state share one bright line: you cannot sell any food that needs refrigeration or other temperature control to stay safe. That single rule is what disqualifies most of the foods people ask about, and it is the reason the list of prohibited foods under cottage food law looks similar from state to state even when the allowed list varies. Regulators treat a food as potentially hazardous when it has a pH above 4.6 and a water activity above 0.85, the warm, moist, neutral zone where bacteria like Salmonella and Clostridium botulinum grow quickly.1U.S. Food and Drug Administration. Evaluation and Definition of Potentially Hazardous Foods A food only needs to clear one of those thresholds to be considered non-hazardous, which is why bread, cookies, hard candy, and fruit jams are almost always allowed and the categories below almost never are.
Meat, Poultry, Fish, and Seafood
Raw and cooked animal products are prohibited across the board. Beef, pork, chicken, turkey, fish, shrimp, and anything containing them cannot be sold as cottage food. The FDA Food Code classifies all animal-origin foods, raw or heat-treated, as potentially hazardous.1U.S. Food and Drug Administration. Evaluation and Definition of Potentially Hazardous Foods
Jerky is the common point of confusion. It looks shelf-stable on the shelf, but most states still ban it. The drying process has to hit specific temperatures to kill pathogens before the meat dehydrates, and without commercial equipment and verified process controls, regulators treat the risk as too high for a home kitchen. A few states with broader food-freedom laws allow certain meat products, but those programs add requirements like mandatory safety training or process verification that go beyond standard cottage food rules.
Dairy and Egg Products
Milk, soft cheeses, yogurt, kefir, and other dairy items cannot be sold as standalone cottage food products. The exception most states carve out is for dairy used as an ingredient in a shelf-stable baked good or candy. Butter in a cookie is fine. A jar of homemade yogurt is not.
Eggs follow the same pattern. Raw shell eggs are a potentially hazardous food because they can carry Salmonella.1U.S. Food and Drug Administration. Evaluation and Definition of Potentially Hazardous Foods Eggs baked into a cookie or cake are fully cooked and generally allowed, but selling raw eggs, quiche, fresh egg pasta, or custards is restricted. Some states also prohibit frostings made with raw eggs while permitting versions built on meringue powder or pasteurized egg products.
Baked Goods That Need Refrigeration
Not every baked good qualifies, and this is where home bakers get caught. The test is simple: if the recipe tells you to refrigerate the finished product, assume it cannot be sold.
That rules out pumpkin pie, sweet potato pie, cheesecake, custard pies, and cream pies. It also rules out cakes and pastries with cream cheese frosting, whipped cream filling, or custard centers. A standard fruit pie usually is allowed because the sugar and acidity in the filling keep it shelf-stable. Pumpkin pie looks similar from the outside but has a custard-style filling with higher pH and enough moisture to support bacterial growth, which puts it on the prohibited side of the line.
Fresh-Cut Produce, Juices, and Sprouts
Whole, uncut fruits and vegetables are raw agricultural products rather than cottage food products in the first place. Cutting, slicing, or juicing them creates a different problem. The FDA Food Code explicitly lists cut melons and raw seed sprouts as potentially hazardous.1U.S. Food and Drug Administration. Evaluation and Definition of Potentially Hazardous Foods
Breaking the skin exposes moist interior tissue to bacteria from the surface, your hands, and your knives, and that exposed flesh at room temperature becomes an ideal growth medium. Fruit salads, cut melon, vegetable trays, zucchini noodles, fresh-pressed juices, and smoothies are all out. Cooked vegetable dishes like soups and stews are equally off-limits because they need refrigeration after preparation.
Dehydrated fruits and vegetables sit in a gray area. Many states allow them because the drying process pulls water activity below 0.85. Some states carve out dehydrated tomatoes and melons specifically and prohibit them, so confirm your state’s list before investing in a dehydrator for commercial production.
Home-Canned and Acidified Foods
Home-canned low-acid foods are the single most dangerous category, and every state bans them. Low-acid foods include most vegetables, meats, poultry, fish, and some tomato varieties, meaning anything with a pH above 4.6.2eCFR. 21 CFR Part 114 – Acidified Foods The reason is botulism. Home-canned vegetables are the most common source of botulism outbreaks in the United States, and the toxin cannot be seen, smelled, or tasted.3Centers for Disease Control and Prevention. Home-Canned Foods
Pressure canning is the only home method that reaches temperatures high enough to destroy C. botulinum spores in low-acid foods.3Centers for Disease Control and Prevention. Home-Canned Foods A boiling water bath tops out at 212°F, which is not enough. Even with the right equipment, the oversight commercial canners operate under is not something a home kitchen can replicate.
Acidified foods like pickles and salsas sit in a middle zone. Federal rules require acidified foods to reach a finished equilibrium pH of 4.6 or below.2eCFR. 21 CFR Part 114 – Acidified Foods Some states let cottage food producers sell pickles, salsas, and similar products if they verify batch pH with a calibrated meter and keep records; others prohibit them outright. Lab testing is often under $25 per sample where it is required.
Fermented Foods, Alcohol, Garlic in Oil, and Pet Treats
Kombucha, kimchi, sauerkraut, and kefir are prohibited in most states. Live cultures keep changing the food’s chemistry after it leaves the kitchen, so the final pH and alcohol content are hard to predict without lab testing. Kombucha has an extra issue: it can develop enough alcohol during fermentation to cross into regulated territory.
A few more categories tend to catch people off guard:
- Alcohol-infused foods like rum cakes and bourbon caramels are restricted in many states because the alcohol itself triggers separate licensing.
- Garlic-in-oil mixtures are specifically identified in the FDA Food Code as potentially hazardous because the anaerobic environment inside the oil is ideal for C. botulinum.1U.S. Food and Drug Administration. Evaluation and Definition of Potentially Hazardous Foods
- Pet treats fall outside cottage food law entirely. Those laws cover human food, and dog treats, cat treats, and other pet foods require a separate commercial feed license in most states.
- Raw seed sprouts are plant products but still classified as potentially hazardous because sprouting conditions are warm, moist, and perfect for bacterial growth.1U.S. Food and Drug Administration. Evaluation and Definition of Potentially Hazardous Foods
Confirming Your State’s Prohibited List
The categories above hold almost everywhere, but the fine print does not. Some states allow acidified foods, dehydrated vegetables, or certain fermented products that others prohibit, and a handful of food-freedom states permit items like jerky under additional requirements. Your state’s department of health or department of agriculture publishes the current list. Search for “cottage food” with your state name and work from the official guidance rather than a third-party summary. Sorting this out before you sell is far easier than responding to a cease-and-desist afterward.
