Keep Food Safe During a Power Outage
Limit refrigerator and freezer opening, track uncertainty, and use official food-safety guidance to decide what to keep or discard.
Keep cold appliances closed
During an outage, keep refrigerator and freezer doors closed as much as possible. Opening the doors lets cold air escape, so plan what you need before opening one and retrieve several items at once. If you have a thermometer, follow official guidance for checking appliance temperatures rather than relying on whether food feels cold.
Avoid repeatedly checking the contents. A closed appliance is more likely to retain its cold than one opened every few minutes. If the power interruption is expected to last, consider whether a cooler and ice are available, while keeping raw foods separated from ready-to-eat food and following safe handling instructions.
Track time and conditions
Write down when the outage began and any temperature readings you can take safely. Also note foods that require refrigeration, including leftovers, dairy, meat, seafood, and certain medicines; medication storage questions should go to a pharmacist or clinician. When the power returns, do not assume every item is safe based only on appearance or smell.
For example, if you do not know how long a container of leftovers was above a safe temperature, mark it as uncertain and consult official food-safety guidance. Tasting a small amount is not a reliable way to test safety.
Use authoritative guidance for decisions
Food safety recommendations depend on how long the outage lasted, appliance temperatures, and the type of food. Use current guidance from a public health or food-safety authority to decide what can be kept and what should be discarded. If a local official issues specific instructions, follow those directions.
Ready.gov provides general power-outage preparedness information, including having an alternative way to charge a phone. For food-specific decisions, consult an official food-safety source such as the relevant public health authority, and use its stated time and temperature guidance rather than applying an unsupported rule of thumb.
Prepare a small outage routine
Keep a basic thermometer and a written note with the start time of an outage. Decide who will check appliances and where to find current official advice. If you discard food, do so safely and follow local waste guidance; do not keep questionable items because they appear normal.
A calm routine is simple: keep doors closed, record what you know, and check authoritative guidance when service returns. That approach helps households avoid unnecessary opening while making careful decisions about uncertain food.
