Which temperature range is called the danger zone because it is conducive to bacterial growth?

• A. 32 F – 40 F
• B. 0 F – 10 F
• C. 136 F – 165 F
• D. 41 F – 135 F

Answer: (D)

Bacteria multiply most quickly in a warm, moist environment, which food-safety guidelines call the danger zone. This zone covers roughly 40°F to 140°F, where many pathogens can double in minutes. The temperature range 41°F to 135°F sits squarely inside that zone, making it conducive to bacterial growth. Cooler temps (near 32–40°F) slow or stop growth, freezing (0–10°F) halts growth, and temperatures above about 140°F start killing many bacteria. So the range 41–135°F is the danger zone.
