The leading cause of food-borne illness is time and temperature abuse. Temperature abuse of food occurs when food is left at temperatures that are above 4°C (40°F) and below 60°C (140°F). This temperature range is commonly called The Danger Zone. Below are the temperatures you should know.

Food Temperatures

Food temperatures, and description of what occurs at that temperature
Temperature Description
100°C (212°F) Temperatures destroy bacteria but not all toxins and spores (e.g., Staphylococcus toxin is not destroyed).
60°C (140°F) Most bacteria won’t survive. Minimum hot holding temperature.
49°C (120°F) Rapid growth of bacteria and production of toxins by some bacteria.
37°C (98°F) Optimal bacterial growth.
16°C (60°F) Some growth of food-borne bacteria may occur
4°C (40°F) Slow growth of some bacteria that cause spoilage may occur. Maximum temperature for refrigerated food and cold holding.
-18°C (0°F) Freezer temperatures

Cooling Food

  • Cool food from 60°C (140°F) within 2 hours to 20°C (68°F)
  • 50°C (122°F) to 20°C (68°F) is the worst range for bacteria growth.
  • Cool food from 20°C (68°F) within 4 hours to 4°C (40°F)
