Has the power gone out in your home due to a storm? Not sure what's safe to eat or what to toss from your refrigerator? The United States Department of Agriculture has a website that lists what to do with each item in your fridge. It warns that appearance and odor are not good indicators of which foods are safe to eat. For example, dairy products like 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.
