Shelf-Stable Food in Connecticut

What Counts as Shelf-Stable?

In Connecticut, a shelf-stable food is any food product that does not require time or temperature control for safety — known officially as a "non-TCS" food. These are products that won't spoil or become dangerous if stored at room temperature. The distinction matters because it determines whether you can sell from your home kitchen or need a licensed commercial facility.

Two scientific measures drive this classification:

Water Activity (a_w)

Water activity measures the available moisture in a food that bacteria and mold need to grow. Pure water has an a_w of 1.0. Most shelf-stable foods have a water activity below 0.85, which is too dry for most harmful bacteria to thrive. Think of it this way: a fresh strawberry has high water activity and spoils quickly, while dried fruit or a cookie has low water activity and stays safe on a shelf for weeks.

pH (Acidity Level)

pH measures how acidic or alkaline a food is on a scale from 0 (very acidic) to 14 (very alkaline). Foods with a pH of 4.6 or below are considered high-acid and are generally inhospitable to dangerous bacteria like Clostridium botulinum. This is why vinegar, jams with proper acid levels, and pickled products can be shelf-stable — but it's also why Connecticut requires jams and jellies to meet the FDA's Standard of Identity (21 CFR 150) to ensure they have adequate sugar-acid balance.

The practical takeaway: if your product needs to be kept in a refrigerator or heated to stay safe, it's not shelf-stable and it's not eligible for Connecticut's cottage food program. Breads, cookies, dry mixes, candies, roasted nuts, properly made jams, and dried herbs all qualify. Cheesecakes, fruit butters, cooked vegetable products, and beverages do not.

Annual Sales Limit

Connecticut raised this cap from $25,000 to $50,000 effective October 1, 2022, through Public Act 22-8. It was one of the largest single increases among northeastern states. The commissioner may request your sales documentation at any time to verify compliance.

If your annual gross sales exceed $50,000, you have two options: obtain a food manufacturing establishment license (which allows broader production in a licensed facility) or stop selling until the next calendar year. There is no intermediate tier or temporary overage allowance.

Where You Can Sell

Connecticut allows cottage food sales through several direct-to-consumer channels — but every sale must be a person-to-person transaction. Here's what's allowed and what's not:

One important detail: even though advertising online is permitted, the actual exchange of product and payment must happen in person. You cannot use DoorDash, Uber Eats, or similar delivery platforms to fulfill cottage food orders.

Storage and Handling Requirements

Connecticut's cottage food regulations include specific rules about where and how you prepare, store, and handle your products. These requirements are checked during your home kitchen inspection and may be verified at any time by DCP or your local health department.

• Kitchen only: All food preparation, packaging, and handling must take place in your home kitchen — the kitchen in your primary private residence. You cannot use an outbuilding, shed, barn, garage, or a second property.
• Permitted storage area: Ingredients and finished products may be stored in the "permitted area" of your home, which includes your kitchen and may extend to rooms like a spare bedroom or dry basement — as long as the space is free of dampness, water, pests, and unsanitary conditions.
• No shared activity: You cannot prepare cottage food products at the same time as other domestic activities — no family meal prep, laundry, kitchen cleaning, or entertaining guests while making food for sale.
• No children or pets: No pets, infants, or children under 12 are allowed in the kitchen during food preparation, packaging, or handling.
• Gloves and utensils: All persons involved in preparation must use single-service gloves, bakery papers, tongs, or other utensils to avoid bare hand contact with ready-to-eat foods.
• No commercial equipment: Commercial-grade equipment like large rotary mixers is generally not allowed because home kitchens lack the three-compartment sinks required to properly wash, rinse, and sanitize that equipment. Standard residential equipment does not need to be NSF-certified.
• Water safety: If your home uses a private well, the water must be tested prior to licensing and at least annually thereafter for coliform bacteria and nitrates. Municipal water is acceptable.
• Septic considerations: If you're on a private septic system, DCP may require an evaluation of your system's capacity to handle additional wastewater from food production, particularly for higher-volume bakery operations.
