What is the danger zone for food contamination in terms of temperature?

• A. 0 to 40 °F
• B. 40 to 140 °F
• C. 140 to 212 °F
• D. 180 to 220 °F

Answer: (B)

The main idea is that many bacteria that cause foodborne illness multiply rapidly when foods sit in a middle range of temperatures, known as the danger zone. This zone spans from 40°F to 140°F. In this window, bacteria can grow quickly—doubling in as little as 20 minutes—so leaving perishable foods out at room temperature can lead to dangerous levels of contamination. Keeping cold foods at 40°F or below slows or stops bacterial growth, while heating foods to temperatures above 140°F helps kill many pathogens. However, some spores may survive or toxins can form, so the safest practice is to minimize time food spends in that zone. Use proper time–temperature control: refrigerate promptly, reheat to safe temperatures, and limit how long perishable items sit at room temperature (about two hours, or one hour if it’s hot).
