Has the power gone out to your home recently? Not sure what's safe to eat or what to toss from the refrigerator? The U.S. Department of Agriculture has a website that lists foods you can keep and ones you should throw away. The department warns that appearance and odor are not good indicators of which foods are safe to eat. For example, milk should be tossed, but butter and processed cheese are fine to keep. Fresh fruits that are cut should be tossed, but an open jar of fruit juice is fine to keep. For the whole list, visit foodsafety.gov.
