How Long Will Food Keep in a Power Outage?

Determining how long food will keep in a power outage all depends on how many times you open and close the refrigerator door. If you keep it shut, only opening a few times here and there then the food may last for about 24 hours maybe even longer. The reason the food can last for so long without power is because the food and fridge is already close and can hold its temperature for a while as long as the door remains shut.
