What Is a TCS Food?
TCS stands for Temperature Control for Safety. These are foods that can support the growth of dangerous bacteria — like Salmonella, E. coli, Listeria, and Clostridium botulinum — when held at temperatures between 41°F and 135°F for more than two hours.
Louisiana's cottage food framework — governed by R.S. 40:4.9 — is specifically designed for "low-risk" foods that don't need refrigeration or active temperature management to stay safe. When a food is classified as TCS, it means it requires either constant refrigeration (at or below 41°F) or active heating (at or above 135°F) to prevent microbial growth that could make a customer seriously ill.
The state's regulatory system doesn't prohibit you from making and selling TCS foods — it just requires that you do so from an inspected, licensed commercial kitchen with the equipment and oversight necessary to manage food safety properly. For home kitchens operating under the cottage food exemption, TCS foods are simply outside the permitted scope.
Bacteria multiply rapidly between 41°F and 135°F. In this range, a single bacterial cell can become millions within just a few hours. TCS foods left in this zone — whether cooling down from cooking or warming up from refrigeration — are a food safety risk that home kitchens are not licensed or equipped to manage under Louisiana's regulatory framework.
Note: Louisiana's statute uses 45°F (not 41°F) as the refrigeration threshold specifically for custard/cream-filled baked goods — one of the few TCS items permitted under cottage food rules with strict handling requirements.
Prepared Meals & Foods That Require a Licensed Kitchen
The following categories of prepared foods — beloved staples of Louisiana cuisine — cannot be sold under the cottage food exemption. Each requires a retail food establishment permit from the Louisiana Department of Health and preparation in an inspected commercial kitchen.
Gumbo, chicken soup, seafood bisque, turtle soup, red bean soup — any cooked, liquid or semi-liquid food containing meat, seafood, or protein requires active temperature control.
Crawfish étouffée, shrimp stew, chicken fricassee, and similar protein-based smothered dishes are TCS foods requiring refrigeration throughout the supply chain.
Jambalaya, dirty rice, and red beans and rice — once cooked with meat, poultry, or seafood, these become TCS foods that require continuous temperature management.
Boudin, andouille, smoked sausage, and other meat products are both TCS foods and animal muscle protein — doubly excluded from Louisiana's cottage food framework.
Natchitoches meat pies, crawfish pies, boudin-stuffed pastries, and other filled savory pies contain animal protein — explicitly excluded from the low-risk foods definition.
Creole cream cheese, fresh ricotta, soft cheeses, yogurt, kefir, and ice cream are TCS dairy foods that require refrigeration, pasteurization oversight, and dairy licensing.
Any product containing fish, crawfish, shrimp, oysters, crab, or other seafood — raw, smoked, pickled, or cooked — falls outside the cottage food framework due to the explicit ban on fish protein.
Any hot cooked meal sold ready-to-eat — whether delivered to customers, sold at a pop-up, or handed over at a farmers market — requires a retail food establishment permit.
Many Louisiana food traditions can be adapted into shelf-stable cottage food products. These are clearly allowed under R.S. 40:4.9:
The Commercial Kitchen Licensing Path
If prepared meals or TCS foods are central to your food business vision, you can still pursue it — you'll just need to move beyond the cottage food framework and obtain a retail food establishment permit. Here's the path forward in Louisiana.
Temperature Requirements for TCS Foods
If you do pursue a commercial kitchen license and begin selling prepared meals, these are the temperature standards required by the Louisiana Food Code for TCS foods at all stages of preparation, holding, and service.
| Situation | Required Temperature | Notes |
|---|---|---|
| Cold holding (refrigerated TCS foods) | 41°F (5°C) or below | Must be maintained continuously; no exceptions for brief warm periods |
| Hot holding (cooked TCS foods for service) | 135°F (57°C) or above | Steam tables, chafing dishes, soup wells must maintain this temp |
| Cooking poultry (whole birds, stuffed) | 165°F (74°C) for 15 seconds | Includes whole chickens, stuffed meats, and reheated poultry |
| Cooking ground meat & sausage | 158°F (70°C) for 1 second | Or equivalent time-temp combinations per Food Code Table A |
| Cooking whole beef, pork, seafood | 145°F (63°C) for 15 seconds | With 3-minute rest time for whole cuts of beef and pork |
| Cooling cooked TCS foods (phase 1) | 135°F → 70°F within 2 hours | Must be cooled rapidly — use ice baths, shallow pans, blast chillers |
| Cooling cooked TCS foods (phase 2) | 70°F → 41°F within 4 more hours | Total cooling time from 135°F to 41°F: 6 hours maximum |
| Custard/cream-filled baked goods (cottage food special rule) | 145°F cooking → 45°F storage | The only TCS-adjacent item permitted under cottage food rules in Louisiana, with strict pasteurized-milk requirements |
