What is the Temperature Danger Zone?

• A. Zone where there is the most rapid bacterial growth, 40-140 F
• B. Zone below 0 F
• C. Zone above 212 F
• D. Zone between 60 and 80 F

Answer: (A)

Bacteria in food grow best within a certain temperature window, so keeping food out of that window reduces the risk of illness. This range, from 40°F to 140°F (4°C to 60°C), is the Temperature Danger Zone. In this zone, bacteria can multiply rapidly, and some can double in as little as 20 minutes, so food left between those temperatures can become unsafe very quickly. That’s why cold foods are kept below 40°F and hot foods above 140°F, to slow or stop growth. The other options don’t describe this risk zone: freezing below 0°F slows or stops growth; boiling above 212°F can kill most bacteria; and 60–80°F is still within the danger zone but doesn’t define the standard boundary where growth accelerates the most.
