Why does food not spoil in the fridge?

At room temperature, most foods go bad within a few hours due to bacterial growth. Therefore, the refrigerator is considered the safest place to keep food fresh for a longer period. The temperature inside the refrigerator is much lower than room temperature, which inhibits the growth of bacteria.

Why does food not get spoiled in fridge?

Food items get spoiled at room temperature because of bacterial growth. Therefore, to keep the food items fresh for a longer period, refrigerator is the safest place. Inside a refrigerator the temperature is much lower than room temperature, which controls the bacterial growth.

At what temperature does meat spoil?

The "Danger Zone" (40 °F-140 °F)

This range of temperatures is often called the "Danger Zone." That's why the Meat and Poultry Hotline advises consumers to never leave food out of refrigeration over 2 hours. If the temperature is above 90 °F, food should not be left out more than 1 hour.
