In tonight's HealthierMe, power outages could be a major problem once hurricane Sandy hits, and even if you're not affected by Sandy, food safety experts want to remind you that warming inside your refrigerator and freezer begins as soon as the power goes out, so try to keep the fridge door closed.
UDSA officials say a refrigerator will keep food safely cold for about four hours if it's left shut, while a full freezer will hold the temperature for about 48 hours if unopened.
After that time, you should throw out your meats, soft cheeses, and leftovers, along with any other produce you've cut up.
