What is the "danger zone" temperature range for bacteria to multiply rapidly?

32° - 100° F
32° - 212° F
40° - 140° F
40° - 212° F

The correct answer is: 40° - 140° F

The "danger zone" temperature range for bacterial growth is recognized as 40°F to 140°F. This range is critical because it is within these temperatures that bacteria can multiply rapidly, potentially leading to foodborne illnesses. Bacteria typically thrive in this temperature range because it is conducive to their growth and reproduction. Below 40°F, bacterial growth slows, and above 140°F, the heat can effectively kill most bacteria or significantly impede their ability to multiply. As a result, food safety guidelines emphasize keeping perishable foods out of this danger zone to reduce the risk of bacteria multiplying to dangerous levels. This knowledge is essential for both food safety and public health, highlighting the importance of proper cooking, storing, and handling of food. Understanding this temperature range helps professionals enforce safe practices in food preparation and storage, thus protecting public health.
