How long can foods last in the freezer after the electricity goes out?

• A. 12 hours
• B. 1 day
• C. 2 days
• D. 1 week

Answer: (C)

After a power outage, the key point is how well the freezer can stay cold. The temperature inside should stay around 0°F (-18°C). If the freezer is full and kept closed, it can keep foods frozen for about 48 hours; if it’s only half full, about 24 hours. The packed mass and any ice in the freezer help maintain the cold, while opening the door lets warm air in and speeds thawing. That’s why two days is the best estimate among the options. If the outage lasts longer or the temperature rises above about 40°F (4°C) for more than a couple of hours, you’d need to assess or discard per safety guidelines.
