Illinois cottage food rules for hot sauce
Updated
On this page8
Yes, and Illinois is one of the few states whose cottage food law names hot sauce outright. Since January 1, 2025, a registered cottage food operation may sell acidified and fermented foods if it either uses a recipe tested by USDA or a cooperative extension, or files a written food safety plan for the product category ("such as pickles, kimchi, or hot sauce") with a pH test [1]. You register each year with your local health department, and the person making the sauce must be a certified food protection manager [1]. This page lays out the two approval paths, how the sauce must be packed, and where you can sell it.
Two ways to qualify a hot sauce
Public Act 103-0903 rewrote 410 ILCS 625/4 and treats a food as acidified when acid is added to bring the finished equilibrium pH to 4.6 or below (with water activity above 0.85), or when it is fermented to pH 4.6 or below [1]. You then pick one path:
| Tested recipe | Food safety plan | |
|---|---|---|
| What you use | A recipe tested by USDA or a cooperative extension system in Illinois or any other state [1] | Your own recipe, covered by a written plan for its product category, following Department guidelines [1] |
| Testing | None stated beyond following the recipe | A pH test of one representative product in the category, submitted every 3 years [1] |
| Paperwork | Show the source if asked | Plan submitted annually when you register [1] |
| Best for | A maker selling a published sauce such as a home canning pepper sauce | A maker with original sauces |
Tested hot sauce recipes are few. The canning hot sauce page covers the ones published by NCHFP and Ohio State. Most sellers with their own recipe will use the plan path. The law does not say who must run the pH test, so ask your health department whether a lab result is expected (see food testing labs).
Tomato sauces get an extra rule: follow a tested recipe exactly, or have a commercial lab test your recipe at your expense, use the same tomato varieties in later batches, and provide test documentation yearly [1]. Cut or pureed fresh tomato and low acid canned foods are prohibited, and garlic in oil is barred unless the garlic oil is acidified [1].
Shelf stable or cold: how it must be packed
The law sets two packing routes for fermented and acidified foods [1]:
- Canned. Processed in a boiling water bath, in a Mason style jar or glass container with a tight fitting lid. A woozy bottle filled hot and capped is not a boiling water bath; if you want to bottle without a water bath, ask your health department first.
- Not canned. Packed in a new, clean container that seals properly, and stored, transported and sold at 41°F or below.
A fermented mash sauce that you do not process in a water bath therefore has to stay refrigerated all the way to the buyer. Fermented foods fall under the same recipe or plan rule as acidified ones [1]; how this book handles ferments finished with vinegar is on fermented hot sauce and the acidified food rules.
Registration and training
Register annually with the local health department where your kitchen is; your sales can extend beyond that area [1]. The fee may not exceed $50, and a department may run a self certification program [1]. The person preparing or packaging the product must be a Department approved certified food protection manager [1]. No sales cap appears in the law [1].
Where and how you can sell
Cottage food must go directly to consumers for their own use and not for resale, so stores and wholesale are out [1]. Allowed channels [1]:
- Farmers markets, including mobile farmers markets
- Fairs, festivals and public events
- Online sales, with the required notice shown at the point of sale
- Pickup at your home or farm (subject to local law), delivery to the customer, or pickup at third party private property with the owner's consent
Shipping is allowed only for foods that do not need time or temperature control, sealed with a tamper revealing seal, and never out of state: a cottage food product "shall not be shipped out of State" [1]. A refrigerated ferment cannot be shipped at all.
The Illinois label and placard
Each package needs the operation's name and unit of local government, the registration number and the county or municipality of registration, the common name, all ingredients by weight, the processing date and federal allergen labeling [1]. It must also carry this statement [1]:
"This product was produced in a home kitchen not inspected by a health department that may also process common food allergens. If you have safety concerns, contact your local health department."
The same notice goes on a placard at a physical display and on the online sales page [1]. The federal elements are on what a hot sauce label must say.
Outgrowing the cottage route
Selling to stores or restaurants, shipping out of state, or bottling without a water bath means a licensed kitchen and the federal acidified food steps: a process authority review, FDA registration and a filed process (see acidified food rules). Ask the Illinois Department of Public Health or your local health department which permit applies.
Confirm with your local health department
Your county or city health department registers cottage food operations and enforces these rules, with the Illinois Department of Public Health setting the guidelines for food safety plans [1]. The law text is listed below. This page was last verified in October 2026.
