Enter Your Situation
Select the food type, how long the power has been out, and your refrigerator or freezer situation. Results are based on USDA food safety guidelines.
What to do:
Planning estimate only. Based on USDA Food Safety and Inspection Service guidelines. Actual food safety depends on many factors including starting temperature, appliance condition, and specific food items. When in doubt, throw it out. Never taste food to determine if it is safe. Consuming spoiled food can cause serious illness — this risk is higher for adults over 65.
Common Questions
How long does food last in the refrigerator without power?
According to the USDA, a refrigerator will keep food safe for up to 4 hours if the door is kept closed. After 4 hours above 40°F, perishable foods enter the danger zone and bacteria multiply rapidly. A full freezer holds temperature for 48 hours; a half-full freezer for 24 hours.
Can I refreeze food that has thawed during a power outage?
You can safely refreeze food that still contains ice crystals or has been held at 40°F or below. If food has been above 40°F for more than 2 hours, discard it — do not refreeze. The USDA states: "When in doubt, throw it out."
Is it safe to eat food that smells okay after a power outage?
No. Never use smell, color, or taste to determine food safety. Many dangerous bacteria — including Salmonella and E. coli — produce no detectable odor or taste. Older adults are at significantly higher risk of serious complications from foodborne illness. When in doubt, discard it.
What foods are safe to keep without refrigeration?
Shelf-stable foods safe without refrigeration include: canned goods, peanut butter, crackers, dry cereals, dried fruits, nuts, hard cheeses (waxed), fruit juices in sealed containers, and bread. Avoid any food that normally requires refrigeration once it has been above 40°F for more than 2 hours.
