What temperature range defines the Danger Zone?

• A. 60-140 degrees F
• B. 32-100 degrees F
• C. 41-135 degrees F
• D. 0-32 degrees F

Answer: (C)

In food safety, the Danger Zone refers to the temperature range where bacteria can multiply rapidly, increasing the risk of foodborne illness. Foods kept cold should stay at 41°F or below, and hot foods should stay at or above 135°F. Within the range from 41°F to 135°F, bacteria can grow quickly, especially if food sits there for more than a short period. That’s why this window is called the Danger Zone: it’s the zone where growth is most likely and time becomes critical. Keeping foods out of this range—either chilling them below 41°F or heating them to 135°F or higher—helps prevent unsafe bacterial growth.

The other ranges don’t align with this concept. They either exclude temperatures where growth can occur (for example, freezing temperatures aren’t a place where bacteria multiply quickly) or they mix in temperatures that won’t reliably prevent growth, which is why they aren’t used to define the Danger Zone.
