What to Throw Out When the Power Goes Out
During power outages, food spoilage can be a serious problem when refrigerators and freezers lose power. Consumers can help avoid spoilage and foodborne illness in their homes by making sure foods stay properly refrigerated during a power outage.
Make sure - before an outage - that the refrigerator is set below 40ºF.
Stock up on non-perishable foods that don't require refrigeration, and choose single-serve sizes if available to avoid the need for refrigeration of unused portions. Consider these easy, healthy, shelf-stable foods:
Breads/Grains: single-serving boxes of cereal, trail mix, energy bars, granola bars, cereal bars, bagels, muffins, crackers, popcorn and chips.
Fruits and Vegetables: carrot and celery sticks and other cut-up raw vegetables, grapes, single-serve applesauce, whole fruit (apples, peaches, bananas), dried fruit mix and juice boxes.
Dairy Alternatives: single-serve milk or soy beverage boxes and non-refrigerated pudding cups.
Meat and Other Protein Sources: cans of tuna, peanut butter (for sandwiches or with celery and apples), nuts and single-serve packages of peanut butter and crackers.
When the Power Goes Out:
During a power outage, keep the refrigerator and freezer doors closed and open them only when necessary.
If power is restored within four hours, items in the refrigerator should be safe to eat. A full freezer will stay at freezing temperatures for two days if the door remains closed. A half-full freezer will stay at freezing temperatures for one day if the door remains closed.
Once the Power is Restored:
When power is restored, check the temperature inside of your refrigerator and freezer. If it has risen to 45ºF or higher, discard any potentially spoiled foods. Such foods include meat, poultry, fish, dairy and egg products, soft cheese, cooked beans, cooked rice, cooked potatoes, cooked pasta, potato salad, custard and pudding.
Allow time for the refrigerator to reach below 40ºF before restocking.
And of course, when in doubt, throw it out.
