When disaster strikes, food can become scarce quickly. This scarcity is not only due to the immediate effects of the disaster but also because compromised infrastructure can disrupt supply chains, making restocking difficult. While emergency services may provide some relief, having a personal supply of food that is safe and readily accessible is invaluable. This foresight is not only practical for emergencies but also for more common situations like power outages, which can occur with little warning.
The integrity of stored food is particularly vulnerable during power outages and floods. Refrigerated and frozen foods are especially at risk since they require consistent cold temperatures to remain safe. When the power goes out, the clock starts ticking on how long your food will stay at a safe temperature. It’s crucial to know how to assess whether your food is still safe to consume and what steps you can take to preserve it as long as possible.
The key to minimizing food loss and the risk of foodborne illness lies in understanding how to maintain safe temperatures. The USDA recommends keeping meat, poultry, fish, and eggs refrigerated at or below 40°F, while frozen food should be kept at or below 0°F. However, when the power goes out, maintaining these temperatures becomes a challenge. The best way to ensure your food remains safe is to keep the refrigerator and freezer doors closed as much as possible. A refrigerator, if left unopened, can keep food safely cold for up to four hours, while a full freezer can maintain its temperature for approximately 48 hours. If the freezer is only half full, it will keep its temperature for 24 hours.
For extended power outages, having a supply of dry ice or block ice on hand can be a game-changer. About 50 pounds of dry ice can keep an 18-cubic-foot full freezer cold for two days. It’s wise to plan ahead by knowing where to purchase dry ice or block ice in your area. If the power outage exceeds four hours, placing dry ice or a block of ice in the refrigerator can help maintain a safe temperature for your food.
Preparedness extends beyond just keeping your refrigerated and frozen foods safe. It’s also important to have a stock of non-perishable, shelf-stable foods that can be eaten cold or heated on an outdoor grill. Items like canned goods, boxed or canned milk, water, and ready-to-eat meals should be part of your emergency food supply. Don’t forget about special needs, such as baby formula for infants and pet food for your animals.
Another aspect of preparedness is considering the layout of your food storage. If you live in an area prone to flooding, ensure that your food is stored on shelves that are safely out of reach of potentially contaminated water. Keeping a digital, dial, or instant-read food thermometer, as well as appliance thermometers in your refrigerator and freezer, is essential. These tools allow you to monitor the temperature and determine if your food has remained safe during a power outage.
In summary, being prepared for food safety during a disaster or power outage requires planning and awareness. By keeping your refrigerator and freezer as cold as possible, knowing how to use dry ice effectively, and having a stock of non-perishable foods, you can ensure that you and your family have access to safe, consumable food even in the worst of times.
