The USDA advises that your refrigerator will keep food safe for up to 4 hours during a power outage.
They also have several important tips about general food safety during a power outage:
- Keep the door closed as much as possible
- Throw out perishable food (meat, poultry, eggs, and leftovers) after 4 hours without power
- After an outage, never taste food to determine its safety
- When in doubt, throw it out!
They say that you will have to evaluate each item separately after an outage.

Frozen Food:
A full freezer will hold a safe temperature for approximately 48 hours. If it is half full, it only holds food safely for one day, but the door has to stay closed.
The food safety website says it IS ok to refreeze some foods IF it still contains ice crystals or is at 40 degrees F or colder. The quality may suffer, but in most cases it is safe. If the food is thawed of at a temperature above 40 degrees F for more than two hours, it will likely have to be discarded.
This chart shows what to do with different frozen foods depending on the temperature and if it has thawed.
Never taste food to determine if is still good or not, health officials warn.
