List two indicators of a properly functioning cold holding unit in a kitchen.

• A. Consistent temperature at or below 40°F; proper door seals and air circulation; uniform temps across shelves.
• B. Hotter than 60°F.
• C. Door seals are irrelevant.
• D. Temperature variance across shelves is fine.

Answer: (B)

Keeping cold holding units functioning means they must maintain safe, cold temperatures and distribute cooling evenly throughout the unit. The two key indicators are: the temperature stays at 40°F (4°C) or below, and the temperatures are uniform across all shelves, which shows that cold air is circulating properly and no area is warming up. Good door seals also support this by preventing warm room air from leaking in, helping maintain that consistent cold temperature.

Why this matters: pathogens grow more slowly at 40°F or below, so maintaining that threshold helps keep food safe. If temperatures rise or vary across shelves, some foods can reach unsafe temperatures even if others stay cold. Conversely, stating that the unit can be hotter than 60°F, that door seals don’t matter, or that temperature variance across shelves is acceptable would all indicate poor function and unsafe food handling.
