Winter storms hit many parts of the country last week, even bringing unusual ice and snow to places in the midwest and south. With power and water outages, people are forced to look for other ways to stay warm and keep food fresh, but the USDA is warning against putting food out in the snow to store because it can be dangerous.

A full freezer can keep its temperature for about 48 hours if it isn’t opened, the USDA says. The refrigerator will stay cold for only about 4 hours if unopened, so it’s best to have a backup plan in case of emergencies. But taking food outside, even if in coolers, should not be one. Even during winter storms, food can spoil because the temperature can fluctuate and the sun can heat coolers (even if they stay closed), and the items are exposed to animals. So, instead of leaving perishable frozen and refrigerated items outside if the power is out, the USDA just offered a cleaner, safer, and easier solution.
“Placing perishable food outside in the snow can lead foods being exposed to varying temperatures, unsanitary conditions, and animals. Instead, fill containers with water and leave them outside to freeze,” it says in a recent tweet. “Use the homemade ice to cool your refrigerator, freezer, or coolers.”

It suggests filling things like empty buckets, milk cartons, or cans with water and leaving them outside to freeze, then putting them in the refrigerator, freezer, or coolers inside.
If you store food outside in the ice and snow longer than 2 hours and have not used a thermometer to keep track of the temperature, it may be spoiled. A full list of refrigerated and frozen foods and when it is safe to re-chill or freeze them and when they should be discarded can be found here.
