# How Long the Food Is Safe After an Outage

How long food lasts in a fridge without power is the one appliance question in this region that arrives with weather attached, and the answer has two halves.

## The published figures

USDA guidance, and worth knowing before you need them.

**A refrigerator holds about four hours** with the door unopened.

**A full freezer holds about 48 hours.** A half-full one, about 24.

The gap between those two freezer numbers is the useful part. Frozen mass is thermal storage — the food itself is what keeps the rest of the food cold — which is why filling empty freezer space with containers of water before a storm is a genuinely effective thing to do and costs nothing.

## The condition every figure depends on

The door stays shut.

Opening it to see how things are going is the single most common way four hours becomes two, and it is completely understandable behavior. A refrigerator that is not running has no way to recover what leaves, so every look costs real time.

If you need something, take everything you need in one opening and plan it before you open the door.

## The second half, which this badge gives you

Most people judge this on the clock and on what the food looks like. Your refrigerator has been keeping a better record.

When the high-temperature alert is acknowledged for the **first** time, the display shows the highest temperature the cabinet actually reached while you were out. Not the temperature now — the peak.

That single number is the decision. A cabinet that touched 44°F for an hour and one that sat at 58°F overnight look and smell identical when you open the door, and the thermometer on the shelf will tell you about neither.

Press clear once. Photograph what it shows. Then deal with everything else — because a second press deletes it and there is no history screen to go back to.

## The rule that actually applies

Above 40°F for more than two hours is the line for perishables in the refrigerator. That is temperature and time, not appearance.

Appearance and smell are unreliable for the organisms that matter, which is the uncomfortable part of this subject: food that has become unsafe frequently looks and smells completely normal.

## Refreezing

If it still has ice crystals in it and has stayed at or below 40°F, it can generally be refrozen with some loss of quality. Fully thawed and warm, no.

## And if the cabinet does not come back properly

After a long outage a refrigerator can take many hours to pull back down, and that is normal rather than a failure. What is not normal is a cabinet that is still drifting a day later with the doors shut — at which point the outage has found something that was already marginal, usually a seal or a condenser that has been quietly closing up for years.
