Around the world, refrigeration is a crucial method for keeping food fresh. The refrigerator slows down food spoiling because the lower temperature slows down bacterial multiplication. The temperature inside a refrigerator is kept a few degrees above the water’s freezing point. 3 to 5 °C (37 to 41 °F) is the ideal temperature range for the preservation of perishable foods.

The Food and Drug Administration of the United States advises keeping the refrigerator at or below 4 °C (40 °F) and keeping the freezer at 18 °C (0 °F).
