What is the Temperature Danger Zone (TDZ) for most perishable foods?

Explanation:
Bacteria multiply fastest in a temperature window where food is not cold enough to slow them down and not hot enough to kill them. For most perishable foods, that window is from 41°F up to 135°F. Staying within this range allows bacteria to grow quickly, which raises the risk of foodborne illness if food is left there too long. That’s why foods should be kept cold at 41°F or lower and hot foods should be held at 135°F or higher, with limited time in between to prevent dangerous growth. The other ranges don’t fit because they either miss part of this growth zone (too cold or too warm) or lie entirely outside it (freezing or very hot ranges).
