how long will meat stay frozen in the freezer if the power goes out?
1 A full freezer will hold its temperature for about 48 hours (24 hours if half-full). 2  Place meat and poultry to one side of the freezer or on a tray to prevent cross-contamination of thawing juices.  Use dry or block ice to keep the refrigerator as cold as possible during an extended power outage.
