Quick answer

Yes. Potatoes last 1–2 months in the pantry and 10–12 months in the freezer. After that, or sooner if stored badly, they spoil: watch for the signs below.

How to tell if potatoes are bad

Smell

Fermented, sour or musty odour.

Texture

Soft, mushy or leaking spots, or wrinkled skin with soft flesh.

Colour

Dark bruising that spreads, or browning inside.

Mould

White, grey or green fuzz — discard soft produce; cut firm produce generously.

Potatoes past the expiration date

Best-by and sell-by

FoodKeeper gives unopened potatoes 1–2 months in the pantry or 1–2 weeks in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.

Past the date

Potatoes past their best-by date are usually safe if stored well; check smell, look and taste before using.
