Fridge storage

How long does corn last in the fridge?

About 1 day for corn. That’s what Well Stockd plans on; the table below has the sources’ own times.

Times are for a fridge at 40°F (4°C) or below. They’re a guide, not a safety guarantee.

How we checked this: each storage time here is checked against the source named beside it, USDA FoodKeeper, USDA FSIS or another, before the page goes live. A time marked “Our estimate” is Well Stockd’s own, since FoodKeeper and FSIS give none. Editorial policy

How long it keeps

Unopened
1 to 2 days in the husk for best sweetness Source: USDA FoodKeeper: Corn on the cob (opens in a new tab)
Opened or cut
Cut kernels hold 3 to 4 days Our estimate: FoodKeeper and FSIS give no time for this.
Freezer
About 8 months (240 days) at best quality. Frozen food stays safe indefinitely at 0°F; the time is about texture and flavor. Source: USDA FoodKeeper: Corn on the cob (opens in a new tab)Compare freezer times for other foods on the printable freezer storage chart.
How to store it
Leave in the husk and refrigerate immediately: sugar converts to starch fast at room temperature.

How to tell if corn has gone bad

Dates are estimates; these are the checks that actually decide it. Don’t taste food to check whether it has gone bad.

Throw it out at once if you see:

  • Mold in the silk
  • Slimy husk

Also a sign it has gone bad:

  • Dry, shrunken kernels

Sources and limits

That’s not long. If you won’t use it in time, freeze it, or check FoodKeeper’s freezing advice for this food.

Well Stockd doesn’t know when this food was harvested, packed, bought, opened or cooked. Write down the date you opened, cooked or refrigerated it, follow the package directions, keep your fridge at 40°F or below, and check the official listing when food safety is in question.

Each time in the table names its source beside it. A time marked “Our estimate” is Well Stockd’s own, because FoodKeeper and FSIS give none for that food in that state, and where our time differs from FoodKeeper’s, the row shows FoodKeeper’s figure too. The number at the top is Well Stockd’s own estimate. It’s a guide, not a safety guarantee: FoodKeeper says storage times are guidelines, and quality varies with how food is grown, handled, shipped and stored. This page was last updated .
