FoodKeeper-based refrigerated planning reference
How long do potatoes last in the fridge?
Well Stockd’s curated reference uses about 60 days refrigerated for potatoes, assuming a refrigerator kept at 40°F (4°C) or below. This is a planning estimate drawn from the app’s FoodKeeper/FSIS-based catalog, not a package date or a safety guarantee.

Unopened, opened, and frozen
The single fridge number above is a planning figure. Most of the questions people actually ask about potatoes turn on whether the package has been opened, so those windows are listed separately here.
- Unopened
- 1 to 2 months in a cool dark place; refrigeration is not recommended
- Opened or cut
- Peeled or cut potatoes hold 24 hours submerged in water
- Freezer
- About 300 days at best quality. Frozen food stays safe indefinitely at 0°F; the window is about texture and flavour.
- How to store it
- Dark, ventilated, away from onions. Do not refrigerate raw potatoes — cold converts starch to sugar and darkens them on cooking. Green patches are solanine; cut them away generously or discard.
How to tell if potatoes has gone bad
Dates are estimates; these are the checks that actually decide it. When more than one of these is present, throw it out rather than tasting to find out.
- Green skin
- Sprouting eyes
- Soft or weeping flesh
- Musty smell
How to use this window
This longer planning window is still affected by packaging, temperature, ripeness, and whether the item has been opened.
Well Stockd does not know when this food was harvested, packed, purchased, opened, prepared, or moved between storage locations. Record the relevant opened, prepared, or refrigerated date, follow package directions, keep your refrigerator at 40°F or below, and use the official item listing when food safety is in question.
Primary sources and limits
The repository catalog identifies USDA FoodKeeper and FSIS typical refrigerated storage guidance as its source. FoodKeeper explains that storage times are guidelines and that actual quality varies with growing, handling, distribution, and storage conditions.
