The commissioner says safe temperatures can be maintained for about four hours in a refrigerator, and at least 24 hours in a freezer. Keep the doors closed.
Thawed food is usually safe if it's still "refrigerator cold."
If the food still contains ice crystals, it is safe to refreeze or cook.
Throw away any perishable food that's been above 40 degrees Fahrenheit for two hours or more.

In New York City, those who depend on food stamps can recoup some of their losses from Hurricane Irene.
The Food Bank For New York City announced Tuesday that recipients who lost their food items to flooding, extended power outages or equipment failure can reclaim the food stamp benefit value. They must file a request form within 10 days of the loss.
New Yorkers are also being urged to donate their unwanted non-perishable food items to their local food pantry.
