Storage Guidelines

Commercial storage guidance for potatoes for fresh consumption (table/fresh-market tubers, cured, stored). Storage life depends on initial quality, maturity, cultivar and handling; this is not a household shelf-life guarantee.

Keep tubers in the dark, because light causes greening and bitter, toxic glycoalkaloids, and avoid storing them too cold, which turns starch into sugars that darken on cooking. Highest freezing point: -1°C. Source: USDA Agriculture Handbook 66 (rev. 2016).
