United States Department of Agriculture said fridges keep food safe for up to four hours during a power outage.
The department said people should keep the fridge door closed as much as possible, and discard perishable foods after four hours without power. This means discarding foods such as meat, poultry, fish and eggs.
US agencies said individuals should never taste food to try to determine if it has gone bad.
