Respond to a disaster
Keeping food safe during a power outage
Keep refrigerator and freezer doors closed and check food safety after power returns.
At home
In an emergency, contact local emergency services and follow official instructions.
First, check this
Keep refrigerator and freezer doors closed as much as possible during an outage. [12]
While the power is out
- An unopened refrigerator keeps food cold for about four hours, according to the US FDA. This estimate depends on keeping its door closed; follow local food-safety advice. [12]
- Check plans for any medication that requires refrigeration with your pharmacist or healthcare provider. [13]
When power returns
- Check the temperature and follow local food-safety guidance for refrigerated and frozen food. Do not rely on smell or appearance alone and never taste food to decide whether it is safe. [12]
- If you are unsure whether perishable food is safe, discard it. [12]
