Which option correctly places the danger zone concept?

• A. The range of temperatures that kill all bacteria
• B. The range of temperatures at which most bacteria multiply rapidly: between 5 and 63°
• C. The range of temperatures where bacteria cannot grow
• D. The range of temperatures that cause food to burn

Answer: (B)

In HACCP practice, the danger zone is the temperature range where bacteria can grow fastest, so controlling time and temperature to keep food out of this zone is key. That range is about 5°C to 63°C. Keeping hot foods above 63°C or cold foods below 5°C minimizes bacterial growth. The other ideas aren’t correct because there isn’t a universal temperature that kills all bacteria, there is a range outside the danger zone where bacteria can’t grow, and temperatures that cause burning have no relation to microbial safety.
