Those who are without power for more than a day may have to throw out whatever is in their refrigerator and freezer, according to disaster tips provided by the U.S. Department of Agriculture.
Food left inside a refrigerator that loses power will stay cool for about 4 hours if unopened, while food in a freezer is OK for up to 48 hours, according to a fact sheet from the USDA.
Meat, poultry, fish and eggs should be kept at 40 degrees, while frozen food should be kept at 0 degrees.
Pack items from the refrigerator in coolers with fresh ice, the fact sheet suggests. Food in the freezer can be packed with block or dry ice.
