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.
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.
Within 2 hours of cooking food or after it is removed from an appliance keeping it warm, leftovers must be refrigerated. Throw away all perishable foods that have been left in room temperature for more than 2 hours (1 hour if the temperature is over 90° F, such as at an outdoor picnic during summer).
Maintain hot TCS food at 135°F or above. Properly cooked roasts may be held at 130°F or above. TCS food must be cooled from 135°F to 70°F within 2 hours and completely cooled to 41°F or below within 6 hours. TCS food prepared from ingredients at room temperature must be cooled to 41°F or below within 4 hours.
Food held between 5oC and 60oC for less than 2 hours can be used, sold or put back in the refrigerator to use later. Food held between 5oC and 60oC for 2-4 hours can still be used or sold, but can't be put back in the fridge. Food held between 5oC and 60oC for 4 hours or more must be thrown away.
Hold cold foods at 41 degrees Fahrenheit or less and check the temperature every four hours. If the temperature of the food at four hours is greater than 41 degrees Fahrenheit, the food must be discarded.
