How long can chicken be left out of fridge is it 3 hours or 4 hours?

Chicken should not be left out of the fridge for more than 2 hours to ensure safety. If the temperature is above 90°F (32°C), this time reduces to just 1 hour. Beyond these time limits, harmful bacteria can multiply, increasing the risk of foodborne illness. It's important to refrigerate or cook chicken promptly.
