How Long Will Food Last When Power Goes Out?
When the power goes out, it’s essential to know how long your food will last to avoid spoilage and foodborne illnesses. The duration for which food remains safe to eat during a power outage varies depending on several factors, including the type of food, the temperature of your refrigerator or freezer, and the length of the outage.
For refrigerated foods, such as dairy products, meat, and leftovers, the general rule is that they can be safely kept for about 4 hours at temperatures of 40°F (4°C) or below. If the power is out for longer than 4 hours, it’s best to discard these items to prevent foodborne illnesses. However, if you can keep the refrigerator door closed as much as possible, the food inside can last up to 48 hours. To extend the shelf life of refrigerated foods, you can use a cooler with ice packs to keep the temperature low.
Freezer foods, on the other hand, can last much longer during a power outage. If the freezer is full, it can remain frozen for about 48 hours, while an empty freezer can keep food frozen for about 24 hours. If the power is out for an extended period, you can insulate the freezer with blankets or towels to maintain the cold temperature. Once the power is restored, it’s crucial to check the temperature inside the freezer and discard any food that has thawed and refrozen.
It’s important to note that certain foods have a shorter shelf life during power outages. Perishable items like meat, poultry, seafood, and dairy products should be prioritized for consumption or disposal first. Non-perishable foods, such as canned goods, dry goods, and shelf-stable items, can be stored for longer periods, even without power.
During a power outage, it’s also essential to monitor the temperature inside your refrigerator and freezer. A digital thermometer can help you keep track of the temperature and ensure that your food remains safe to eat. If the temperature inside the refrigerator rises above 40°F (4°C) or the freezer above 0°F (-18°C), it’s best to discard the food to avoid any health risks.
By understanding how long food will last during a power outage and taking appropriate precautions, you can minimize waste and ensure the safety of your family’s meals. Always have a backup plan, such as a generator or portable cooler, and stay informed about the duration of the power outage to make informed decisions about your food storage.
