Why is it necessary to hot hold foods at 60 C 140 F or hotter?
Bacteria that cause food borne illness multiply quickest between 4°C and 60°C (40°F - 140°F). The Danger Zone is this temperature range in which bacteria and spoilage bacteria grow quickest. Lower temperatures prevent the bacteria from growing to dangerous levels. Temperatures above 60°C will kill the bacteria.
Cook all TCS food to required temperatures and times. Maintain hot TCS food at 135°F or above.
The USDA did issue an advisory that “A minimum temperature of 135 degrees for a maximum of 8 hours, or a minimum temperature of 140 degrees Fahrenheit indefinitely also would be adequate to ensure food safety.”
Holding Temperature For Hot Food
The appropriate holding temp for hot foods is 135 degrees Fahrenheit or above.
Once a food is heated or cooked, the food must be maintained at a temperature to kill or limit the growth of pathogens (disease-causing organisms). The correct hot holding temperature is 135°F or above.
Maintain hot food at 135°F or above. Properly cooked roasts may be held at 130°F or above. Food made in-house and reheated for hot holding must reach an internal temperature of at least 165°F for 15 seconds.
Food that has not been used within two hours, should either be reheated until it is steaming hot and put back in hot holding or chilled down as quickly as possible to 8˚C or below. If it has been out for more than two hours throw it away.
Hot foods should be kept at an internal temperature of 140 °F or warmer. Use a food thermometer to check.
It is very important to keep food hot until serving to prevent harmful bacteria from growing. This includes foods comprising or containing meat, fish, eggs, milk, soft cheese, cereals (including rice and pasta), pulses and vegetables. If this is not possible, hot food can be displayed below 63°C for a maximum 2 hours.
If you're preparing several foods that get "done" at different times, you often can successfully hold most hot foods for about 15 to 20 minutes in a preheated oven set to 200 to 250°F. For longer than this, check frequently with a food thermometer, to assure the food is remaining at a temperatures of 140°F or above.
Can you keep food warm at 170 degrees?
Some ovens actually will have a "warm" setting, which is usually 170 to 200 F, or a warming drawer, which is meant to keep foods at a level, warm temperature. If your oven has neither, set it to 200 to 250 F.
Before using any foods, check your refrigerator and freezer thermometers. If the fridge is still at or below 40 °F, or the food has been above 40 °F for only 2 hours or less, it should be safe to eat.

The State Sanitary Code now requires that the entire mass of all cooked and refrigerated potentially hazardous food which is to be reheated must be reheated to 165 degrees Fahrenheit or above within two hours, and held above 140 degrees Fahrenheit until served.
Hot foods must be at 135°F or above before placing in a hot holding unit. After placing food on a steam table, stir regularly to avoid cold spots. If leftover food is reheated for hold holding, it must reach an internal temperature of 165°F in all parts of the food before placed in the steam table.
Hot foods must be stored above 63 degrees Celcius to prevent the excessive growth of bacteria. Hot foods can be kept below this temperature for a maximum of two hours before being used, returned to above 63 degrees Celcius or chilled.
To prevent time-temperature abuse, hot foods should be held at or above 135 F and cold foods should be held at or below 41 F.
Note: There are three important temperatures to remember when cooking meat or eggs at home: Eggs and all ground meats must be cooked to 160°F; poultry and fowl to 165°F; and fresh meat steaks, chops and roasts to 145°F. Use a thermometer to check temperatures.
- Ground meat—including beef, pork, and other meat.
- Injected meat—including brined ham and flavor-injected roasts.
- Mechanically tenderized meat.
- Ground seafood—including chopped or minced seafood.
- Eggs that will be hot-held for service.
Keep hot food hot and cold food cold. Always use a thermometer to check food temperatures. 135°F to 41°F or below within a total of six hours. The faster food is cooled, the better.
This range of temperatures is often called the "Danger Zone." Never leave food out of refrigeration over 2 hours. If the temperature is above 90 °F, food should not be left out more than 1 hour.
How long can cooked food sit out at 70 degrees?
TWO HOURS is the MAXIMUM time perishable foods should be at room temperature (ONE HOUR at temperatures 90 degrees F and higher). This INCLUDES the time they're on the table during your meal. Just ONE bacterium, doubling every 20 minutes, can grow to over 2,097,152 bacteria in 7 hours!
Lukewarm food is dangerous as it is a perfect environment for bacteria to thrive. If cooked food is not stored above 63°C, it should be used up within two hours of cooking. Ensure the first batch of cooked food being hot held is served first.
Don't turn your oven on full blast, though. Instead, reheat food on a lower heat (around 200-250 degrees) and add a dash of oil or butter to keep the meat moist. This method normally takes 10-15 minutes. FYI: It takes the longest since you have to wait for the oven to preheat, but we think it's worth it.
The food is safe if it has reached a high enough temperature for a long enough time. Examples of safe time/temperature combinations include: 80°C for at least 6 seconds, 75°C for at least 30 seconds, 70°C for at least 2 minutes. Reheating means cooking again, not just warming up.
The best plan is to put leftovers in the refrigerator right after your meal. Food that is sitting out for a party or picnic should be chilled after two hours at typical room temperature. If it's above 90 degrees Fahrenheit (32 degrees Celsius) or more, food should not sit out for more than one hour.
Continue to monitor and record food for proper cooling time and temperature each hour. At 70°F, the food should cool down to 41°F within 4 hours.
When you display hot food, e.g. on a buffet, you should use suitable hot holding equipment to keep it above 63°C. If this is not possible, you can take food out of hot holding to display it for up to two hours, but you can only do this once.
When reheating food that will be hot-held, you have to be especially careful, as bacteria may have had a chance to accumulate on the food. For this reason, independent of the type of food involved, reheat food to a minimum internal temperature of 165 degrees Fahrenheit, or 74 degrees Celsius.

Rapid reheating to 165°F is needed to kill bacteria which have grown in the food while the food was cooling from 135°F to 41°F. 4. Food that needs to be reheated to 165°F are ones that can support the rapid growth of bacteria; i.e., potentially-hazardous foods.
What is the minimum hot holding temperature for hazardous foods?
Hot holding units must hold hot food at a temperature at or above 60oC (140oF). before putting food into the unit. Preheat the food to 74oC (165oF) before putting it into the unit. (140oF) is maintained.
The temperature range between 5°C and 60°C is known as Temperature Danger Zone. This is because in this zone food poisoning bacteria can grow to unsafe levels that can make you sick.
Controlling the temperature of food is extremely important in ensuring that food is safe to eat, and you must ensure that food is always cooked, cooled, chilled or reheated properly to minimise the risk of harmful levels of bacteria in the food that you sell.
Hazard: Bacterial growth Cover foods and hold hotter than 60oC (140oF) Check temperature of food every 2 hours If food is less than 60oC (140oF) for less than 2 hours, reheat food to 74oC (165oF) and increase equipment temperature control until a temperature of greater than 60oC (140oF) is maintained.
To put it simply, hot foods must stay hot (above 140°F) and cold foods must stay cold (below 40°F). When foods are held between 40 and 140°F, bacteria can grow rapidly to levels that can cause you or your guests to get sick. This temperature range is called the “danger zone” and should be treated as a big party no-no.
Hot foods must be stored above 63 degrees Celcius to prevent the excessive growth of bacteria. Hot foods can be kept below this temperature for a maximum of two hours before being used, returned to above 63 degrees Celcius or chilled.
Keep TCS food outside of the danger zone (410F and 1350F; 50C and 570C ): Pathogens grow within this temperature range. If food is held in this range for 4+ hours, throw it out.
Keep high-risk food at 5 °C or below or above 60 °C to avoid the temperature danger zone and food poisoning. Store raw foods below cooked foods. Store food in suitable, covered containers. Avoid refreezing thawed foods.
Bacteria grow rapidly between the temperatures of 40° F and 140° F. After food is safely cooked, hot food must be kept hot at 140° F or warmer to prevent bacterial growth.
Serve or keep food hot in chafing dishes, slow cookers, and warming trays. Be aware that some warmers only hold food at 110 °F to 120 °F, so check the product label to make sure your warmer has the capability to hold foods at 140 °F or warmer. This is the temperature that's required to keep bacteria at bay!
What temperature should hot food be served at Servsafe?
Prevent time-temperature abuse and contamination: Keep hot food at 135˚F (57˚C) or higher. Keep cold food at 41˚F (5˚C) or lower. Keep raw meat, fish, and poultry separate from ready-to-eat food.
