With power out to well over a million households at the height of damage from this week's tropical storm, cleanup continues both outside and inside for New Jersey residents.

A refrigerator will keep food safe for up to 4 hours when left closed during a power outage, according to food safety resources from the U.S. Department of Agriculture.

A full freezer will hold a safe temperature for roughly 48 hours (24 hours if it is half full and the door remains closed), also according to the USDA.

Federal officials recommend after four hours without power, throw out refrigerated perishable food such as meat, poultry, fish, eggs and leftovers.

As for frozen items, food may be safely refrozen if it still contains ice crystals or is at 40°F or below — however, its quality may suffer.

Never taste food to determine its safety and "when in doubt, throw it out," according to USDA officials.

Among items to throw away after a few hours without power to a fridge:

  • Cut fruit
  •  Cut vegetables
  •  Deli meat
  •  Raw meat, poultry, fish, seafood
