Food Safety During a Power Outage
It should be safe as long as power is out for no more than four hours. Keep the door closed as much as possible. If you know a power outage is likely, freeze water in plastic bags (or purchase frozen cold packs) and pack the refrigerator with them as soon as the power goes out. A few on each shelf can help keep the food below 40˚F longer. Discard any perishable food (such as meat, poultry, fish, eggs, and leftovers) that has been above 40˚F for over two hours.
Some homeowner’s insurance policies or power companies cover the cost of food lost during a power outage. Check with your insurance company or power supplier to see if you can be reimbursed so you can restock when the power comes back on.

Discard Times for Frozen Foods After Power Outage
Thawed or partially thawed food in the freezer may be safely refrozen if it still contains ice crystals or is at 40˚F or below. Partial thawing and refreezing may affect the quality of some food, but the food will be safe to eat. If you keep an appliance thermometer in your freezer, it’s easy to tell whether food is safe. When the power comes back on, check the thermometer. If it reads 40˚F or below, the food is safe and can be refrozen. Otherwise discard it.
