If the power goes out, do I need to throw out all the food in my refrigerator and freezer?

To minimize the loss of food during a power outage, limit the number of times you open your refrigerator or freezer door. If the doors remain closed, refrigerated food can remain safely cold for about 4 hours; frozen food can remain safe for 2 days if the freezer is full and the doors remain closed.
