What is the Temperature Danger Zone?

• A. 0-32 degrees
• B. 32-40 degrees
• C. 40-140 degrees
• D. 140-200 degrees

Answer: (C)

The idea being tested is what range of temperatures constitutes the Temperature Danger Zone in food safety. Bacteria that can cause illness multiply most rapidly when food sits in a certain temperature window, from 40°F up to 140°F. In this range, many pathogens can double in number in a relatively short time, so even small amounts of contaminated food can become hazardous quickly. That’s why keeping cold foods at 40°F or below slows or stops bacterial growth, and hot foods should be kept at 140°F or above to reduce bacterial counts and prevent growth. Temperatures below 40°F inhibit growth, while temperatures above 140°F help kill or reduce bacteria, making food safer if held at those levels. In practice, this zone is avoided for holding food for extended periods, and foods are either refrigerated or kept hot to stay out of it.
