Beware: The Bacteria Danger Zone
The "bacteria danger zone" refers to the temperature range between 40F and 140F (4C and 60C) in which bacteria can grow and multiply rapidly. This range is particularly concerning because it encompasses temperatures commonly found in kitchens, restaurants, and other food preparation areas.
Keeping food out of the bacteria danger zone is essential for preventing foodborne illness. Bacteria can double in number every 20 minutes in the danger zone, so even a short period of time can lead to significant bacterial growth. To prevent this, foods should be kept at or below 40F or at or above 140F.
There are a number of ways to keep food out of the bacteria danger zone. Refrigerators and freezers should be kept at the proper temperatures, and food should be refrigerated or frozen within two hours of cooking. Hot food should be kept hot until it is served, and cold food should be kept cold until it is eaten. Additionally, food should not be left out at room temperature for more than two hours.
