If the power is out for less than 2 hours, then the food in your refrigerator and freezer will be safe to consume. While the power is out, keep the refrigerator and freezer doors closed as much as possible to keep food cold for longer. If the power is out for longer than 2 hours, follow the guidelines below: â¢ For the Freezer section: A freezer that is half full will hold food safely for up to 24 hours. A full freezer will hold food safely for 48 hours. Do not open the freezer door if you can avoid it.
Much of that depends on how long your power has been out, and how much you have inside your fridge or freezer. According to the Canadian Food Inspection Agency (CFIA), a full freezer will stay frozen for 48 hours, while a half-full freezer will keep its cool for 24. A refrigerator, meanwhile, will stay keep food cold for four hours, as long as it isn't opened. Some rules of thumb to keep in mind, via CFIA: Discard any thawed food that has been at room temperature for two or more hours, and any food that has an obvious unusual colour or odour.
