Power outages happen, especially when severe weather rolls in. Whether it’s a storm, wind event, or unexpected grid issue, losing power can put your fridge and freezer contents at risk. Here’s exactly what you should know to keep food safe and avoid waste.

1. Keep Those Doors CLOSED
The most important rule during a power outage? Don’t open the fridge or freezer unless you have to. Cold air escapes quickly, and keeping the temperature down is the best way to protect your food. In fact, an unopened refrigerator will keep food safely chilled for up to 4 hours after the power goes out.
2. How Long Will Food Stay Cold?
- Refrigerator: About 4 hours if you keep the door shut.
- Freezer:
- Up to 24 hours if it’s only half full.
- Up to 48 hours if it’s packed and the door stays closed.
After that time, temperatures rise, and perishable items can enter the “danger zone” (above 40 °F / 4 °C), where bacteria can grow quickly.
3. What to Toss, and What You Might Keep
Once the power is restored or you know how long the outage lasted, here’s what to do:
Throw out:
✔ Meat, poultry, seafood
✔ Eggs
✔ Milk and cream
✔ Leftovers and cooked dishes
✔ Soft cheeses and dairy products
These foods can become unsafe if they’ve been above 40 °F for more than a few hours.
Still okay?
✔ Hard cheeses
✔ Butter and margarine
✔ Uncut fruit
✔ Condiments like ketchup or mustard
These tend to hold up better, but always give them a check before using.
4. Use a Thermometer If You Can
If you have a fridge or freezer thermometer, check the food’s temperature once power is back. If it’s 40 °F or below, it’s safe to refreeze or cook, as long as the texture seems normal. Without a thermometer, look for ice crystals or items that feel cold to the touch; those are often okay to save.
Handy Prep Tips for Next Time
If outages are common where you live, try these tips:
- Place a few jugs of water in the freezer ahead of time; this adds extra “thermal mass” and helps keep everything colder longer.
- Group foods together in the freezer so they help each other stay cold.
- Have a cooler and ice packs ready to transfer food if the outage goes on longer than a few hours.
Bottom Line: Safety First
When it comes to food and power outages, the rule of thumb is simple: don’t open the doors, know the time limits, and when in doubt, throw it out. It’s better to be cautious than risk foodborne illness or upset stomachs later.
