How to Keep Your Food From Going Bad in a Power Outage

Estimated read time 5 min read


There’s rumbling outside again. A thunderstorm is brewing, and for many, that can almost guarantee a power outage is soon to follow. When your electricity is out, you’ve got several things to worry about: staying cool, navigating in the dark and keeping the food in your fridge from going bad. If the power is out for several days, you’ve also got to start worrying about preserving the food in your refrigerator. That’s why it’s good to have a plan by preparing for the possibility of a power outage in your home. It’s an especially good idea now, as extreme weather events like hurricanes and heat waves continue to affect those in the US.

Losing a fridge full of food is costly, inconvenient and potentially dangerous if you’re unable to get out to a store in the middle of a storm, like last week’s Hurricane Debby, which made landfall in a terrifying way. But there are ways to get ready ahead of time so that you can save all or most of your perishables. Here’s what to do.

When possible, prepare to save your food before a power outage strikes

Before you face a power outage, it’s best to take a few steps to prepare in case you need to save your food. The recommendation from the US Centers for Disease Control and Prevention is to have the following items on hand: 

  • Appliance thermometers for both your refrigerator and freezer, so you can monitor if their temperatures rise and you need to start removing food. The fridge should not rise above 40 degrees Fahrenheit, and the freezer should not rise above 0 degrees F.
  • A cooler and frozen gel packs, in case you have to take food out of the fridge to keep it cold.
  • Dry ice or block ice to keep food cold inside the fridge, if you think the power will be out for a long time.

What to do with your food when the power first goes out

When an outage hits, keep your refrigerator and freezer doors closed — don’t open them up unless you absolutely need to, and even then, try to do so quickly so as not to let the cold air out. If the doors stay closed, your food can stay safe for up to four hours in a refrigerator, 48 hours in a full freezer and 24 hours in a half-full freezer, according to the CDC. 

Once you’ve passed the four-hour mark (or if you see the temperature inside the fridge has risen to over 40 degrees F) and the power is still out, it’s time to start moving food out of the fridge. If perishable food has been left in the fridge after that point, you’ll have to throw it all out. 

The exception here would be if you have dry ice. You can put the dry ice on the top shelf of your freezer and the bottom shelf of your refrigerator, and it will keep your perishables cold. You need about 3 pounds of dry ice per cubic foot of freezer space, which should keep food cold for at least two days. Just make sure you’re aware of how to safely handle dry ice before using it.

Separate your food into two groups

First, you’re going to make two piles: Food that absolutely must be kept cold, and food that is safe to leave on the counter until the power is back on. 

Foods that do not need to be kept cold

The following foods can be safely kept out of the fridge: 

  • Butter (for 1-2 days) 
  • Peanut butter
  • Most cooking oils, with the exception of nut oils
  • Herbs
  • Potatoes
  • Most fruits and vegetables
  • Bread
  • Coffee
  • Honey
  • Ketchup, mustard and hot sauce

Foods that need to be kept cold

The following foods must be kept at 40 degrees F or lower to prevent bacteria growth and spoilage: 

  • Dairy products (cheese, milk, whipped cream, sour cream)
  • Eggs
  • Meats, poultry and fish (cooked or uncooked)
  • Cut fruit and vegetables
  • Leftovers 

How to keep perishable food cold without a fridge

Once you’ve got your pile of perishable food, it’s time to pull out your cooler and ice packs. Put a layer of frozen foods at the bottom. Then put a layer of foods from the fridge on top of that layer. Top it off with another layer of frozen foods. If you don’t have any ice or ice packs, go to the store and buy some if it’s safe to do so. 

Layer ice or ice packs around the food in the cooler — don’t just throw it all on top or bottom. Distributing the ice will keep the food at a more consistent temperature. Move your fridge thermometer inside the cooler to keep an eye on the temperature.

If you don’t have a cooler, you can use your freezer instead — it’s insulated and will keep your food cold as long as you leave the door shut and keep a fresh supply of ice in it. To prevent melting ice from turning your freezer into a pond, put ice in bowls and place them around the food.

You should never taste food to see if it’s gone bad — when in doubt, throw it out, the CDC advises. Throw away any food with unusual odors, colors or textures right away. In terms of frozen foods, you can safely refreeze or cook thawed frozen food that is at 40 degrees F or below, or that still contains ice crystals.
