Cover the freezer with blankets, quilts or sleeping bags to further insulate the freezer and help food stay frozen longer. After power is restored, check all frozen foods to determine the extent of thawing. Dispose of any food that is discolored or smells spoiled. If in doubt, throw it out. Meat and fish spoil quickly at temperatures above 40 degrees F. Other quick-spoiling foods include milk, custards, creamed foods and any foods containing mayonnaise or eggs.
Hard cheeses keep well, even at room temperature.
You might also try placing bags of ice in the refrigerator or place food in a cooler or ice chest. Discard meat, seafood, dairy products and cooked foods that are not cold to the touch. This will reduce the possibility of accidental burns. If using a fuel-burning camp lantern indoors, make sure you properly ventilate the room by cracking open a window. Never leave candles or lanterns unattended.
