How Long Will Food Last in the Refrigerator Without Power?
When the power goes out, the first thing that comes to mind for many people is the safety of their food. The question of how long food will last in the refrigerator without power is a common concern during power outages. The answer to this question depends on several factors, including the type of food, the temperature inside the refrigerator, and the duration of the power outage.
Under normal circumstances, the refrigerator is designed to maintain a temperature of 40°F (4°C) or below, which slows down the growth of bacteria and preserves food. If the power goes out, the refrigerator will start to lose its cooling ability, and the food inside will begin to warm up. According to the United States Department of Agriculture (USDA), the following guidelines can help you determine how long food will last in the refrigerator without power:
- Unopened packages of raw or cooked meat, poultry, seafood, and eggs: These can last up to 1 to 2 days in the refrigerator. If the power is out for longer than 2 days, it is best to discard these items.
- Unopened packages of dairy products: Milk, cheese, and yogurt can last up to 7 days in the refrigerator without power. However, if the temperature inside the refrigerator rises above 40°F (4°C), discard these items immediately.
- Unopened packages of fresh fruits and vegetables: These can last up to 1 to 2 days in the refrigerator without power. Once opened, they may last up to an additional day or two.
- Unopened packages of bread and rolls: These can last up to 1 to 2 days in the refrigerator without power. Once opened, they may last up to an additional day or two.
It is important to note that the above guidelines are based on the assumption that the refrigerator door is kept closed as much as possible during the power outage. If the door is left open, the temperature inside the refrigerator will rise faster, and the food will spoil more quickly.
In addition to following the guidelines above, there are some steps you can take to help preserve your food during a power outage:
- Keep the refrigerator door closed as much as possible: This will help maintain the cold temperature inside the refrigerator.
- Use a cooler with ice or ice packs to keep food cold: If the power is expected to be out for an extended period, consider using a cooler to keep your perishable food cold.
- Check the temperature inside the refrigerator: Use a refrigerator thermometer to monitor the temperature inside the refrigerator and ensure it remains at or below 40°F (4°C).
By following these guidelines and taking appropriate precautions, you can help ensure that your food remains safe to eat during a power outage.
