Like other root vegetables, potatoes can last several weeks if not months, before they spoil. They don’t need to be refrigerated, but they need to be kept in a cool, dark and dry place. If they become exposed to moisture, mold will set in and they’ll quickly spoil. Even if they start to sprout, they can still be eaten, says Kantha Shelke, but it’s very important to remove every part of the greenish sprout before cooking as the ends can be toxic to some people. Nonetheless, it’s worth eating according to Shelke. “When a potato sprouts, it’s going through a biochemical process and creating a lot of nutrients to support the new plant, or baby. The potato is therefore in an enhanced state, and very nutritious. Just cut off all the sprouts and eyes, and cook the center of the spud which should still be nice and firm."
