SILVER SPRING, Md., Feb. 13, 2020 /PRNewswire/ -- It's the winter season and parts of the country are facing extreme weather conditions and power outages. In fact, a power outage can happen at any time, so it's important to have a plan in place to safely handle your food during an emergency. Read on to learn the best way to keep your food safe in case a power outage does take place.

Be Prepared and Plan Ahead

Use a refrigerator and freezer thermometer, and check it regularly to ensure that the refrigerator temperature is at or below 40°F and the freezer is at or below 0°F.
Plan for ice. Know where you can get dry or block ice. Make ice cubes and freeze containers of water or gel packs to help keep food cold when there is a loss of power.
Keep coolers on hand to store refrigerated food if the power will be out for more than 4 hours.
Freeze refrigerated items that you may not need immediately and group food together in the freezer.
Stock your pantry with a few days' worth of ready-to-eat foods that do not require cooking or refrigeration.

If the Power Goes Out

Cold temperatures slow the growth of harmful bacteria. Keeping food at safe temperatures is key to reduce the risk of foodborne poisoning.

Keep refrigerator and freezer doors closed as much as possible. The refrigerator will keep food cold for about 4 hours, and a full freezer will keep the temperature for approximately 48 hours (24 hours if half full) if the door remains closed.
Use ice (dry or block ice, ice cubes, and frozen containers of water/gel packs) to keep your refrigerator and freezer as cold as possible.

When Power is Restored

Before eating any food after a power outage, check the temperatures inside your refrigerator and freezer.

If the power was out for no more than 4 hours, refrigerated food should be safe as long as the doors were kept closed. When the power comes back on, check the temperature in the refrigerator or of the food. Discard any perishable food (such as meat, poultry, seafood, milk, eggs, or leftovers) that has been at refrigerator temperatures above 40°F for 4 hours or more. Perishable foods with temperatures that are 45°F or below (measured with a food thermometer) should be safe but cooked and consumed as soon as possible.
If the freezer thermometer reads 40°F or below, food is safe and may be refrozen. If you did not have a thermometer in the freezer, check each package to determine its safety; you can't rely on appearance or odor. If the food still contains ice crystals or is 40°F or below, it is safe to refreeze or cook.
Be aware that perishable foods that are not kept adequately refrigerated or frozen may cause food poisoning if eaten, even after they are thoroughly cooked.
