Tennessee is one of the few states that lets home sellers offer perishable, temperature-controlled foods — with one critical rule about how you sell them.
TCS stands for Time/Temperature Control for Safety. A TCS food is any product that must be kept at specific temperatures — either hot or cold — to prevent the growth of harmful bacteria. If a food needs to be refrigerated, frozen, or held hot to stay safe, it's a TCS food.
This is the critical dividing line in Tennessee's cottage food rules. While both shelf-stable and TCS foods are permitted, they follow very different sales channel rules. Understanding whether your product is TCS determines where and how you can sell it.
Common characteristics that make a food TCS include high moisture content, neutral or low-acid pH (above 4.6), protein-rich composition, and the presence of dairy, eggs, or cooked starches that support bacterial growth at room temperature.
Under the Tennessee Food Freedom Act, perishable products requiring refrigeration may only be sold in person, directly to the consumer — or through an agent or employee selling in person on your behalf. No online orders, no shipping, no retail store placement, and no wholesale for TCS products.
This table shows exactly which sales channels are available for each product type. The difference is significant — shelf-stable products can reach customers in many more ways.
| Sales Channel | Shelf-Stable | TCS / Perishable |
|---|---|---|
| Direct to consumer — in person | ✓ Allowed | ✓ Allowed |
| Farmers markets & events | ✓ Allowed | ✓ Allowed |
| Via agent or employee (in person) | ✓ Allowed | ✓ Allowed |
| Home delivery (you deliver) | ✓ Allowed | ✓ Allowed |
| Online orders | ✓ Allowed | ✗ Not allowed |
| In-state shipping | ✓ Allowed | ✗ Not allowed |
| Retail stores | ✓ Allowed | ✗ Not allowed |
| Wholesale to restaurants | ✗ Not allowed | ✗ Not allowed |
| Interstate shipping | ✗ Not allowed | ✗ Not allowed |
The practical takeaway: If you're building a business around TCS foods, your sales model will center on farmers markets, pop-ups, local delivery routes, and home pickup. These are highly effective channels — many Tennessee sellers build strong local followings through weekly market appearances and social media-driven pre-orders with in-person pickup.
The line between TCS and non-TCS isn't always obvious. Some foods that seem perishable are actually shelf-stable, and vice versa. Here are common examples to help you classify your product:
Custard pies, cream puffs, and eclairs contain dairy and egg-based fillings that must be refrigerated.
High moisture, dairy, and egg content make cheesecake a classic TCS product requiring cold storage.
Cooked pasta and sauces with dairy or protein are TCS. Dried, uncooked pasta alone is shelf-stable.
Fresh salsas that aren't canned and rely on refrigeration for safety are TCS products.
Cheese, butter, cream, and yogurt made from pasteurized milk — allowed under HB 130 (2025), sold in person only.
Standard baked goods without cream fillings are shelf-stable — low moisture and water activity.
High-acid pickles processed in a water bath and sealed are shelf-stable when pH stays below 4.6.
High sugar content and proper canning make jams shelf-stable. Follow tested recipes for safe processing.
Candy with low water activity is shelf-stable. Caramels, fudge, brittles, and toffees all qualify.
When in doubt: If you're unsure whether your product is TCS, the safest approach is to treat it as perishable and follow the in-person-only sales rule. You can also consult the UT Extension service for guidance on testing your product's pH and water activity.
Under the Tennessee Food Freedom Act, the answer is no — as long as you produce food in your private home kitchen. The TFFA exempts home kitchens from state licensing, permitting, and inspection for both shelf-stable and TCS products.
However, there's one absolute boundary: if you produce food in any facility other than your personal residence, you need a food manufacturing license from the Tennessee Department of Agriculture (TDA). This includes church kitchens, community centers, restaurant kitchens, shared commercial spaces, and incubator kitchens. It doesn't matter what you're making — the moment you leave your home kitchen, the cottage food exemption no longer applies.
For TCS products specifically, this means your home refrigerator, freezer, and cooking equipment are your primary tools. There's no requirement to have commercial-grade appliances, but you are responsible for maintaining safe temperatures throughout production, storage, and transport.
Health department access: While TDA does not inspect cottage food kitchens, the Tennessee Department of Health retains the right to access your production facility if investigating a reported foodborne illness linked to your products. This is the only circumstance under which a state agency can enter your home kitchen.
The TFFA doesn't prescribe specific temperature protocols in the statute, but standard food safety principles apply — and following them protects both your customers and your business. These are the temperature guidelines every TCS seller should know:
Refrigerated TCS foods must be stored and transported at 41°F or below.
Hot TCS foods must be maintained at 135°F or above during service and transport.
Bacteria multiply rapidly in this range. TCS foods should not remain in the danger zone for more than 2 hours total.
If reheating TCS foods for hot holding, reach 165°F within 2 hours for safety.
Getting TCS foods safely to a farmers market or customer pickup requires planning. Use insulated coolers with ice packs or frozen gel packs to maintain cold temperatures during transit. For hot items, insulated food carriers and chafing-style setups at your booth can keep products above 135°F. Invest in a digital probe thermometer and check temperatures regularly — it's your best tool for proving your food stayed safe.
All Tennessee cottage food labeling requirements apply equally to TCS products. Your label must include your name, address, phone number, ingredients, net weight, lot number or date, and the required disclaimer statement. For TCS products, it's good practice to also include storage instructions (e.g., "Keep Refrigerated") and a use-by date, even though the statute doesn't explicitly require them. See the Label Requirements page for the full list.
