New Mexico uses a simple governing standard: any food that is shelf-stable and does not require refrigeration is generally permitted. Here is a complete breakdown — open, restricted, and prohibited — so you know exactly where your products stand.
Unlike many states that publish a fixed list of approved products, New Mexico's Homemade Food Act operates on a non-TCS standard. If your food does not require temperature control for safety — meaning it is shelf-stable and does not need refrigeration to prevent bacterial growth — it is generally permitted. The law does not enumerate every product you can or cannot make; instead, it draws a single bright line between TCS and non-TCS foods.
This framework gives New Mexico home sellers significant flexibility. Sellers unsure whether a specific product qualifies can contact the NMED Food Program or consult a Process Authority for a product-specific determination. NMSU's Food Safety Laboratory is one such resource in-state.
A TCS food is one that requires specific temperature conditions — typically refrigeration below 41°F or heating above 135°F — to prevent the growth of harmful bacteria. Fresh meats, dairy products, cooked proteins, fresh-cut produce, and foods with moisture and protein that support bacterial growth are all TCS. If your food can safely sit on a shelf at room temperature for its intended shelf life, it is almost certainly non-TCS.
Every product falls into one of three categories. Items marked Restricted are allowed but require extra attention — read each condition carefully before selling.
The [VERIFY] flags in the Restricted column reflect items where the TCS determination depends on your specific recipe, pH, water activity, or processing method. Contact the NMED Food Program (food.program@state.nm.us) or a New Mexico process authority for a product-specific ruling before you list or sell. Selling a TCS product without authorization can result in a fine and an order to stop sales.
The non-TCS standard exists because certain food characteristics — particularly the combination of available moisture (measured as water activity, or aw) and a neutral pH — create environments where harmful bacteria like Salmonella, Listeria, and Clostridium botulinum can grow to dangerous levels without any visible signs of spoilage. A properly baked cookie or a high-sugar jam has neither the moisture nor the pH conditions that support this growth. A fresh cream sauce does.
New Mexico does not publish its own pH or water activity thresholds in the Homemade Food Act text — it incorporates the FDA Food Code standard by reference (found on page 21 of the NMED Retail and Manufactured Food Field Guide). The general thresholds used in food safety are pH 4.6 or below (sufficiently acidic to inhibit most pathogens) and water activity 0.85 or below (sufficiently dry to inhibit bacterial growth). Foods that meet both thresholds are generally non-TCS.
For products that fall in a grey zone — certain nut butters, fermented foods, shrubs, or acidified sauces — a Process Authority can test your specific recipe and confirm its classification. In New Mexico, NMSU's Food Technology program is a starting point. NMED's food program can also provide guidance at no cost.
This is one of New Mexico's more unusual rules. The Homemade Food Act specifically requires that food be produced at the seller's private farm, ranch, or residence. If you rent time in a commercial kitchen — even once — your products are no longer covered by the Homemade Food Act. You would then need a commercial manufactured food permit from NMED (annual fee $200, annual inspections required) to continue selling. Plan accordingly before signing up for any shared kitchen space.
