how do you know when potatoes are bad

Potatoes are bad if they show any of the following signs: they become soft, squishy, or mushy; their skin becomes shriveled or wrinkly; they leak liquid; they emit a bad or sour smell; strange spots or dark blemishes appear on the skin; or the inside looks discolored or rotten when cut open. Sprouts on potatoes mean they are nearing spoilage, but they can be eaten if the sprouts and any green parts are removed. Eating bad potatoes can cause unpleasant symptoms due to toxins like solanine, so it’s best to discard potatoes with these signs of spoilage.
