Describe the two-stage cooling rule for hot foods?

• A. Cool from 135°F to 70°F within 2 hours, then from 70°F to 41°F within the next 4 hours.
• B. Cool to 50°F in 1 hour, then to 40°F in 6 hours.
• C. Cool to 90°F in 2 hours, then to 60°F in 4 hours.
• D. Cool to 40°F immediately

Answer: (A)

The main idea here is keeping hot foods out of the bacterial danger zone by cooling them in a controlled, time‑based way. The two-stage rule requires cooling from 135°F down to 70°F within 2 hours, then continuing from 70°F to 41°F (or lower) within the next 4 hours. This six‑hour window minimizes the time that foods spend between 41°F and 135°F, where bacteria can multiply rapidly, and ends with the food safely stored at 41°F or below.

That exact progression is why the correct option fits best. It states cooling first to 70°F within 2 hours and then to 41°F in the next 4 hours. Other choices miss key parts: they either use the wrong intermediate temperature or wrong timing, or propose an immediate drop to 40°F, which isn’t how the rule is applied.
