Dispose of any food that is discolored or smells spoiled. If in doubt, throw it out. Refrigerated food To avoid losing the cold air in your refrigerator, don't open doors unnecessarily. 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. Cooked and cured meat will keep for several days in a closed refrigerator.
Hard cheeses keep well, even at room temperature.
Again, if in doubt, throw it out. You might also try placing bags of ice in the refrigerator, or place food in a cooler or ice chest. Cooking during an outage Never use charcoal briquettes to cook or heat food indoors. Charcoal briquettes produce carbon monoxide. Odorless and colorless, a build-up of carbon monoxide can be deadly.
