The storm rolled through at 9pm. The lights flickered twice and quit.
Now it's noon the next day, the house is quiet, and you're standing in front of the refrigerator with your hand on the door.
Open it, and the clock speeds up. So what's actually still safe?
Most people guess. The numbers below are the real ones - straight from federal food safety guidance - and they're shorter than most folks think.
The fridge: about 4 hours
An unopened refrigerator keeps food at a safe temperature for about 4 hours after the power goes out, per the food safety charts at FoodSafety.gov.
After that, perishables that spend more than 2 hours above 40°F need to go:
- Meat, poultry, and seafood
- Milk, soft cheeses, and eggs
- Leftovers and anything already cooked
- Cut fruits and vegetables
Here's the hard part: spoiled food often looks and smells just fine. Never taste food to decide. When in doubt, throw it out.
The freezer: 24 to 48 hours
A full freezer holds a safe temperature for about 48 hours. Half full, closer to 24 hours - less frozen mass, less cold to hold.
Two habits make the difference:
- Keep the door shut. Every peek costs you cold air you can't get back.
- Check for ice crystals. Food that still has ice crystals, or has stayed at 40°F or below, can safely be refrozen.
A cheap appliance thermometer in both the fridge and freezer removes the guesswork. It's the difference between "I think it's fine" and knowing.
Stretching the clock
- Group frozen items together so they hold each other cold.
- Around the 4-hour mark, move meat and dairy into a cooler with ice.
- 50 pounds of dry ice will hold a full 18-cubic-foot freezer for about 2 days.
- If an outage is in the forecast, freeze water bottles ahead of time - they buy you hours, then become drinking water as they thaw.

The shelf that doesn't care
Every outage teaches the same lesson: the food that wins is the food that never needed power in the first place.
Canned goods don't watch the weather. A pantry with fully-cooked canned meat - real beef, ground beef, and chicken with up to a 25-year shelf life - turns a spoiled-fridge week into an inconvenience instead of a problem. It's ready to eat straight from the can, no cooking required.
Never tried it? A 3-can sampler pack is the low-commitment way to find out what you'd want more of.
Final thoughts
You can't control when the power comes back. You can control what's on the shelf when it goes out.
Know the two numbers - 4 hours for the fridge, 24 to 48 for the freezer. Keep the doors shut. And keep a corner of the pantry stocked with food that doesn't need either one.
