What is the temperature danger zone?

Explanation:
The temperature danger zone is the range where bacteria multiply quickly in foods: 41°F to 135°F. Keeping perishable foods within this window for too long lets microbes grow fast, increasing the risk of foodborne illness. That’s why safe practice is to refrigerate foods at 41°F or below and hot-hold foods at 135°F or above. The other ranges don’t represent the zone where growth is most rapid—freezing (0–32°F) slows or stops growth, and temperatures well above 135°F are used for cooking or hot holding, which aims to reduce microbes rather than allow their rapid growth.
