The refrigerator: how long will foods remain safe without power? Â· All foods: at least 4 hours, if the fridge is left unopened. Â· Discard after 4 hours without power: Meat, poultry, fish, milk, eggs, cooked leftovers, soft cheeses, deli cold cuts/salads and other perishable foods.
During and after a power outage, the USDA says food âshould be safe as long as power is out no more than 4 hours. Keep the door closed as much as possible. Any food that comes into contact with meat juices should also be tossed. From there, each item just has to be evaluated on its own using the USDAâs chart.
