Which of the following is NOT a safe method for cooling foods?

Leaving food at room temperature to cool is not a safe method because it allows food to remain in the temperature danger zone, which is typically between 40°F (4°C) and 140°F (60°C). This temperature range is conducive to the rapid growth of bacteria that can cause foodborne illnesses. Proper cooling methods are critical for ensuring food safety and preventing bacteria from multiplying.

Using an ice bath allows foods to cool quickly by being surrounded by ice, effectively lowering the temperature. Cooling food in small batches ensures that it's cooled more rapidly than larger quantities, reducing the risk of bacterial growth. Chill sticks or paddles also help to transfer heat away from the food quickly, promoting safe cooling. Each of these methods actively works to maintain foods at safe temperatures, unlike leaving them uncovered at room temperature.
