The USDA provides the following information:

The publication “A Consumer’s Guide to Food Safety: Severe Storms and Hurricanes” can be downloaded and printed for reference during a power outage.

Steps to Follow to Prepare for a Weather Emergency:

  • Use appliance thermometers in your refrigerator and freezer to help determine if food is safe during power outages. Refrigerator temperature should be 40° F or lower and the freezer should be 0° F or lower.
  • Freeze refrigerated items such as leftovers, fresh meat, and poultry that you may not need immediately—this helps keep them at a safe temperature longer.
  • Freeze containers of water for ice to help keep food cold in freezer, refrigerator, or coolers in case of power outage. You can also use melted ice for drinking water.
  • Purchase or make ice cubes and freeze gel packs in advance.
  • Plan ahead and know where to purchase block ice and dry ice, just in case.
  • Have coolers on hand to keep the refrigerator food cold in case the power is out for more than 4 hours

If the Power Goes Out:

  • Keep the refrigerator and freezer doors closed as much as possible.
  • A refrigerator will keep food cold for about 4 hours if you keep the door closed.
  • A full freezer will keep its temperature for about 48 hours (24 hours if half-full)
  • If the power is out for an extended period of time, buy dry or block ice to keep the refrigerator as cold as possible. Fifty pounds of dry ice should keep a fully-stocked 18-cubic-feet freezer cold for two days.

When the Power Is Restored:

  • Check the temperature in the refrigerator and freezer. If the thermometer reads 40° F or below, the food is safe.
  • If no thermometer was used in the freezer, check each package. If food still contains ice crystals, it’s safe.
  • Discard any perishable food (such as meat, poultry, fish, soft cheeses, milk, eggs, leftovers and deli items) that have been kept in a refrigerator or freezer above 40° F for two hours or more.
  • Never taste food to determine its safety!
  • When in Doubt, throw it Out!
