The Temperature Danger Zone is defined as the range of temperatures where bacteria grow rapidly. What is that range?

• A. 40 to 140 F
• B. 0 to 32 F
• C. 140 to 212 F
• D. 60 to 80 F

Answer: (A)

The main idea here is understanding the Temperature Danger Zone—the range where bacteria can grow quickly in foods. The correct range is 40 to 140 F. Within this window, many common foodborne bacteria multiply rapidly, so keeping perishable foods either below 40 F or above 140 F helps prevent dangerous bacterial growth. Why the other ranges aren’t correct: 0 to 32 F is freezing, which slows or stops most bacterial growth; 140 to 212 F is hot enough to kill many bacteria and is outside the danger zone; 60 to 80 F sits inside the danger zone but doesn’t define the full range where rapid growth can occur, since the danger zone actually spans from 40 to 140 F.
