Which temperature range is considered the danger zone?

• A. Between 0 and 5°C.
• B. Between 5 and 63°C.
• C. Between 63 and 100°C.
• D. Between -10 and 0°C.

Answer: (B)

Bacteria grow most rapidly in the temperature range where food is not cold enough to slow them and not hot enough to kill them. This danger zone is between 5°C and 63°C. In this window, many pathogens can multiply quickly, increasing the risk of foodborne illness if food sits there too long. Keeping foods refrigerated at or below 5°C slows or stops growth, while heating or hot-holding foods above 63°C helps kill bacteria and prevent growth. The other ranges describe refrigeration (0–5°C), cooking/hot holding (63–100°C) where heat reduces or eliminates microbes, and freezing (-10 to 0°C) where growth is essentially paused.
