Here’s a simple way to make sure your food will stay safer longer if the power goes out: keep your freezer full. Some jugs or freezer bags filled with water will do the trick.
• If you lose power, a freezer that is half full will hold food safely for up to 24 hours.
• But a full freezer will hold food safely for twice as long — up to 48 hours.
So to be prepared, fill up some plastic jugs or freezer bags with water and freeze.
If your power does go out, you can find out how long specific foods will stay safe here.
