The food danger zone in Celsius is 4°C to 60°C. That’s the range where bacteria can grow quickly, so perishable food should be kept below 4°C or above 60°C.

Quick scoop

  • Danger zone: 4°C–60°C.
  • Why it matters: Food left in this range too long can become unsafe because bacteria multiply rapidly.
  • Practical tip: Keep cold food cold and hot food hot.

Note

Some food-safety guides use slightly different cutoffs, such as 5°C–60°C or local health-code variations, but 4°C–60°C is the most commonly cited standard.
