Safe Food Temperatures: A Kitchen Temperature Chart and Guide
Keeping food out of the temperature danger zone is one of the most important parts of food safety. The danger zone is the range between 41°F and 135°F, where bacteria grow fastest, and it applies to both hot and cold food. This guide covers the safe temperatures for cooking, holding, and storing food, the ideal temperature for your kitchen itself, and the simplest ways to check that food is safe to eat.
Hot Food Safe Temperatures
Hot foods need to be cooked to a specific minimum internal temperature to reduce the risk of bacteria and germs that cause food poisoning. A food thermometer or a food service temperature monitoring system should be used to confirm food has been heated to the right temperature.
- 135°F: Cooked vegetables need to reach at least this temperature before serving.
- 145°F: Beef, pork, bacon, ham, seafood, and fish served right away need to reach this temperature and hold it for at least 15 seconds.
- 155°F: Ground beef, ground pork, and eggs need to reach this temperature and hold it for at least 15 seconds.
- 165°F: All poultry needs to reach at least this temperature and hold it for at least 15 seconds. Reheated foods also need to reach this minimum.
There are some exceptions. With certain cuts of beef, for example, you have several time-and-temperature options that are all considered safe:
- 130°F for at least 121 minutes.
- 140°F for at least 12 minutes.
- 145°F for at least 3 minutes.
Cooked food should rest for a few minutes after it comes off the heat. The temperature keeps rising during the initial rest, and that carryover heat continues to kill bacteria. Check the temperature after the food has rested, and if it has not reached the safe minimum, keep cooking until it does.
Cold Food Safe Temperatures
Cold foods need to stay at 41°F or below. Frozen foods should be kept at 0°F or below to protect quality and stop bacterial growth. Your refrigerator should be set to 40°F or lower to keep stored food safe, and a reliable thermometer or monitoring sensor makes it easy to confirm your appliances are holding the right temperature.
What Is the Temperature Danger Zone?
The temperature danger zone is the range between 41°F and 135°F, where bacteria multiply fastest. Within this range, the amount of bacteria on food can double in as little as 20 minutes. Food should not stay in the danger zone for more than two hours, or more than one hour if the surrounding temperature is above 90°F. To keep food safe, refrigerate it promptly, hold hot food above 135°F, or cool it properly before storing. Warming trays, slow cookers, and steam tables help keep hot foods above the zone, and refrigeration or ice keeps cold foods below it.
How Should You Hold Hot and Cold Foods?
When holding hot food for a period of time, such as on a buffet, the minimum safe temperature is 135°F. Cold food being held should stay at 41°F or below. Hot and cold foods should never be held close enough to affect each other, because the hot food will cool and the cold food will warm until one of them drifts into the danger zone. Use warming stations for hot food and ice baths or cooling zones for cold food, and keep them in separate, temperature-appropriate storage during prep and service.
What Is the Recommended Temperature for a Kitchen?
The kitchen itself should be kept between 68°F and 76°F for a comfortable, functional work environment. When a kitchen runs hot, it becomes harder to hold cold foods safely and easier for prepped food to drift toward the danger zone. Good ventilation and air conditioning keep the room within a safe range for cooking and food prep.
What Is the Best Way to Check Food Temperature?
To check food with a thermometer, insert it into the thickest part of the food, away from bone or fat, and make sure the tip does not touch the container or the cooking surface. Check the temperature in a few different spots to confirm the food has cooked evenly, since uneven cooking can leave cold spots where bacteria survive.
What Temperature Should Leftovers Be Reheated To?
Leftovers need to be reheated to an internal temperature of 165°F to be safe. Stir liquids and sauces and heat food evenly so there are no cold spots where harmful microorganisms can survive. Whether you reheat on the stovetop, in the oven, or in the microwave, use a thermometer to confirm the food has reached 165°F before serving.
Monitoring Food Temperatures Automatically
Checking temperatures by hand works, but it only tells you the temperature at the moment someone looks, and it is easy to skip during a busy shift. For coolers, freezers, and hot-holding units, E-Control Systems offers wireless temperature monitoring that tracks every unit around the clock and sends an alert the moment a temperature drifts out of a safe range. Every reading is stored automatically and is ready for a health inspection. To see how it works, take a look at our food service temperature monitoring solutions, and for the foods that need this control most closely, see our guide to TCS foods.
Frequently Asked Questions
What is the temperature danger zone in a kitchen?
The temperature danger zone is the range between 41°F and 135°F, where bacteria grow fast enough to make food unsafe. Storing food at safe temperatures and using proper cooking methods keeps food out of this range and lowers the risk of foodborne illness.
How long can food stay in the danger zone?
Food should not stay between 41°F and 135°F for more than two hours, or more than one hour if the surrounding temperature is above 90°F. Bacteria can double in about 20 minutes, so refrigerate food promptly, hold it above 135°F, or cool it properly before storing.
How cold should a refrigerator be to store food safely?
Your refrigerator should be kept at 40°F or lower to prevent spoiling and slow bacterial growth. Freezers should be kept at 0°F or below to protect the quality of frozen foods. A thermometer or monitoring sensor makes it easy to confirm your appliances are holding safe temperatures.
Should you keep hot and cold foods separate?
Yes. Keep hot foods above 135°F and cold foods below 41°F, and do not store or serve them together unless they are properly insulated. Held too close, the hot food cools and the cold food warms until one drifts into the danger zone. Use warming stations for hot food and ice baths or cooling zones for cold food.
