The "danger zone" for bacterial growth is identified as the temperature range between 41°F and 135°F. This range is critical because it provides optimal conditions for bacteria to thrive, multiply, and potentially lead to foodborne illnesses. Temperatures below 41°F can slow down or inhibit bacterial growth, while temperatures above 135°F can kill most harmful bacteria.

Understanding this temperature range is essential for food safety, as it informs safe food handling practices. For example, food should not be kept in the danger zone for extended periods during preparation and storage to minimize the risk of contamination and spoilage. This knowledge is crucial for anyone involved in food service or personal food handling to ensure that food remains safe for consumption.
