Smoked meat spends hours at low heat, which is exactly where food safety rules matter most. This checklist walks through a cook in order and gives the numbers from the USDA Food Safety and Inspection Service (FSIS) smoking page, its “Danger Zone” page, its grilling page, and the UK Food Standards Agency’s Cooking your food guidance. Where the two countries differ, both are shown. All Celsius or Fahrenheit conversions are ours.
Before the Smoker: Thaw and Marinate Cold
FSIS says to thaw meat completely before smoking. Smoking uses low temperatures, so frozen meat lingers in the Danger Zone (40-140°F, or 4-60°C) where bacteria multiply. Thaw in the refrigerator, and cook or refreeze within 1 or 2 days. Marinate in the refrigerator, and boil any marinade that touched raw meat before using it on cooked food. FSIS also warns against partially cooking ahead: it is acceptable only if the food goes straight from the microwave or stove into the hot smoker. In its 2024 grilling and smoking release, USDA adds that raw meats and cooked or ready-to-eat food need separate cutting boards and utensils.
In the Smoker: Air Temperature and Two Thermometers
FSIS wants two thermometers: one for the food, one to keep the smoker’s air temperature between 225 and 300°F (107-149°C) throughout. It estimates 4 to 8 hours for smoking meat or poultry, and says timing depends on the cut, size and weather, so the thermometer decides when it is done. Oven-safe food thermometers can stay in the meat during the cook, while an instant-read thermometer is for checking after the meat comes out. It also says to use smokers made of materials approved for contact with meat and poultry, not makeshift containers such as galvanized steel cans.
Internal Temperatures: USDA vs UK FSA
USDA gives one target per meat, measured with a food thermometer:
- Beef, pork, lamb and veal steaks, chops and roasts: 145°F (63°C), then rest at least 3 minutes.
- Ground beef, pork, lamb and veal: 160°F (71°C).
- Poultry: 165°F (74°C).
The FSA takes a different approach: a time and temperature pair at the middle of the food. Its table lists 60°C (140°F) for 45 minutes, 65°C (149°F) for 10 minutes, 70°C (158°F) for 2 minutes, 75°C (167°F) for 30 seconds and 80°C (176°F) for 6 seconds, with 70°C for 2 minutes as its headline figure. The two systems are not identical, so follow the guidance for your country rather than mixing them.
Holding: Where the Danger Zone Begins and Ends
FSIS says bacteria grow most rapidly between 40°F and 140°F, and can double in as little as 20 minutes. To hold food, keep hot food at or above 140°F (60°C). FSIS also says never to leave food out of refrigeration over 2 hours, or over 1 hour if the temperature is above 90°F (32°C).
The FSA defines the same idea with different edges: 8 to 63°C (46-145°F). That makes the upper limit 63°C, slightly higher than USDA’s 60°C. The two agencies set the hold line in slightly different places, so use the one for your country.
After the Cook: Leftovers
- Time to fridge: FSIS’s smoking page says to refrigerate meat and poultry within 2 hours of removing it from the smoker, in shallow containers, cut into smaller portions or slices. The FSA also says two hours. FSIS’s grilling page adds the 1-hour limit above 90°F, which the smoking page does not repeat.
- How long to keep: FSIS says use within 4 days or freeze. The FSA says eat leftovers within 48 hours or freeze. That is a real difference.
- Reheating: the FSA says reheat until steaming hot throughout and only reheat once. FSIS’s grilling page gives 165°F (74°C) or steaming hot for reheating fully cooked items such as hot dogs.
Hot Smoking Only
The FSIS smoking page describes smoking as slow cooking in an air temperature of 225-300°F and does not cover cold smoking. The FSA’s cooking guidance does not address smoking either. So this checklist applies to hot smoking. For questions outside it, FSIS lists its Meat and Poultry Hotline at 1-888-674-6854.
