Which temperatures are critical in NBC safety practices?

• A. Keep cold items at 41°F (5°C) or below and hot items at 135°F (57°C) or above when applicable.
• B. Keep cold items at 32°F (0°C) or below and hot items at 150°F (66°C) or above.
• C. Keep cold items at 50°F (10°C) or below and hot items at 120°F (49°C) or above.
• D. Keep cold items at 41°F (5°C) or above and hot items at 135°F (57°C) or below.

Answer: (A)

Maintaining proper holding temperatures is essential to keep foods safe. Cold items must be kept at 41°F (5°C) or below to slow or stop bacterial growth. Hot items must be kept at 135°F (57°C) or above to stay out of the danger zone and minimize bacterial growth during service. This pairing directly reflects the standard NBC safety practice for cold and hot holding, ensuring foods stay within safe temperatures during storage and service.

Why this pairing fits best: it uses the widely taught thresholds that keep foods out of the range where bacteria multiply rapidly. The other options drift from these established limits—one suggests freezing at 32°F for cold, which isn’t the standard cold-holding guideline, and hot-holding numbers that are either too low or inconsistent with the accepted minimum of 135°F. Keeping cold at 41°F or below and hot at 135°F or above provides a clear, practical rule for safe food handling.
