Plan Food Storage During a Power Outage
A power outage calls for a simple plan: limit refrigerator and freezer openings, track when the outage begins, and use official food safety guidance before deciding what to keep.
Prepare before the lights go out
Keep appliance doors closed as much as possible during an outage. A refrigerator or freezer can retain cold for a limited period, but how long depends on conditions and the appliance. Do not rely on a remembered estimate as a guarantee that food remains safe.
If an outage is possible, make sure household members know where a flashlight is and how to get updates. A written note with the outage start time can help you make decisions later. Ready.gov recommends having alternative ways to charge a phone during a power outage, which can help preserve access to alerts and guidance.
Reduce unnecessary door openings
Avoid opening the refrigerator to look for food or check its temperature repeatedly. Decide what you need before opening the door, take those items together, and close it promptly. Keep the freezer closed as well; opening it to rearrange packages works against keeping the contents cold.
If you have a safe way to monitor appliance temperature, follow official instructions for interpreting it. Do not assume that touch, smell, or appearance can establish whether food is safe. Some harmful contamination does not create an obvious odor or visible change.
Make decisions with current guidance
When power returns, check current food safety recommendations for refrigerated and frozen foods, including the length of the outage and how warm the appliance became. Apply the guidance to the specific food and its storage conditions. If you are unsure about a perishable item, choose the safer option rather than tasting it.
For example, a closed freezer with food that remains solidly frozen may require a different decision from a refrigerator that warmed for an extended period. Treat such examples as prompts to consult official guidance, not as a universal rule for every appliance or product.
Plan for the next interruption
Keep a short outage kit together with a flashlight, charged power bank, and any thermometer or written instructions you rely on. Store the relevant official guidance where it can be reached without internet access, or note a trusted source to consult when service returns. Ready.gov’s power outage preparedness page is useful for preparing the household’s broader response, including backup phone charging.
After an outage, replace supplies that were used and make a note of what worked. A calm routine—closed doors, recorded timing, and decisions based on food safety guidance—helps households avoid both unnecessary waste and unsafe guesses.
