What are some ways to keep food cold during a power outage?
A full freezer can maintain its temperature for about 48 hours if left unopened, while a half-full freezer keeps items cold for about 24 hours. A closed refrigerator can keep food inside at a safe temperature for about four hours.Reducing the temperature of a freezer or refrigerator to its lowest level before a storm lowers the temperature of the items inside and help foods last longer in a power outage. Filling any empty space in the freezer and refrigerator with frozen containers or bags of ice reduces airflow, which also helps maintain cold temperatures. Source: foodsafety.gov
