New Mexico Cottage Food Canning Rules: Selling Pickles, Salsa, and Fermented Foods

Canning is where New Mexico's cottage food rules get genuinely complicated. The state-level law permits qualifying non-TCS foods, but acidified and fermented foods fall outside the standard unlicensed home-kitchen exemption. Local regulations in Albuquerque and Bernalillo County add separate restrictions that catch a lot of home producers off guard — especially those building a business around Hatch chile salsa or pickled products.

What the State Law Actually Says

Under the Homemade Food Act, non-TCS (non-time/temperature control for safety) foods are allowed from home kitchens. For canned products, the critical distinction is between high-sugar preserves and acidified or fermented foods.

High-sugar preserves are clearly permitted. Fruit jams, jellies, fruit butters, and marmalades where the sugar concentration is high enough to inhibit bacterial growth qualify as non-TCS foods. These are shelf-stable by nature and fall squarely under the Homemade Food Act's exemption.

Acidified foods are not permitted under the standard home-kitchen exemption. Products like pickles, salsas, hot sauces, relishes, and pickled vegetables require a commercial kitchen, formal plan review, process authority evaluation, and an annual food processor permit.

Fermented foods follow the same rule. Sauerkraut, kimchi, kombucha, and other fermented products also require commercial processing rather than the unlicensed home-kitchen exemption.

The pH Testing Requirement

You can't just guess that your salsa or pickle recipe is acidic enough. For acidified and fermented products, pH and water activity testing is part of the process-authority analysis; a passing pH does not make these products eligible for the standard home-kitchen exemption. The most reliable path is to submit your recipe to a food process authority for laboratory analysis.

NMSU's Extension Food Technology Program at the Food Safety Laboratory accepts product submissions for pH and water activity testing. They can also conduct a full process review and issue a formal Process Review Letter — documentation that confirms your recipe meets the required thresholds. This letter is valuable if a market manager or local health inspector questions your product's safety.

The general benchmarks: non-TCS foods generally need an equilibrium pH at or below 4.6, or a water activity (a_w) at or below 0.85. These benchmarks help classify shelf stability, but meeting them does not make acidified or fermented foods eligible for the standard home-kitchen exemption.

Albuquerque's Local Ban

Here's the catch that derails many business plans. The City of Albuquerque and Bernalillo County enforce their own environmental health codes, and those codes explicitly classify acidified and fermented foods — including salsas, pickled products, canned vegetables, hot sauces, and fermented beverages — as prohibited from home kitchen production.

This isn't a gray area. Albuquerque's Environmental Health Department bans these products regardless of pH testing results. Even if your Hatch chile salsa tests well below pH 4.6, you cannot legally produce and sell it from a home kitchen within Albuquerque city limits or unincorporated Bernalillo County.

To sell acidified or fermented products, including in Albuquerque, you need a permitted commercial kitchen, a formal plan review, a process authority evaluation, and an annual food processor permit from NMED.

Outside Albuquerque: Do Not Assume Home Production Is Allowed

Being outside Albuquerque and Bernalillo County does not by itself make acidified or fermented products eligible for the home-kitchen exemption. For those products, follow the commercial-kitchen, process-review, and permit path and confirm any additional local requirements.

That said, farmers' market managers retain the authority to set their own rules. Some markets may require you to show your Process Review Letter or proof of pH testing before accepting you as a vendor, in addition to the applicable permits.

Specific Products: What Falls Where

Hatch green chile salsa. Acidified food — requires commercial processing, formal plan review, a process authority evaluation, and an annual food processor permit. It is also prohibited from home kitchens in Albuquerque.

Pickled jalapeños or pickled vegetables. Same commercial-processing rules as salsa; the vinegar brine does not substitute for the required review.

Hot sauce. Acidified food. Same commercial-processing requirement, with the separate Albuquerque restriction as well.

Kombucha. Fermented beverage. Requires commercial processing and a process authority evaluation; it is also prohibited from Albuquerque home kitchens.

Fruit jam or jelly. High-sugar preserve — clearly permitted statewide, including Albuquerque. No pH testing required if the sugar content is sufficient for shelf stability.

Apple butter or fruit butter. Generally qualifies as a high-sugar preserve if properly formulated. When in doubt, test.
