Are sprouting potatoes really toxic?

  Hmmm. I just cut the sprouts off when I peel them…..and have never gotten sick from it, so I hope they aren't toxic. I think having them in a cool, dry place helps them last longer.

  The potato itself isn't toxic, unless it's turned green. The sprouts are, though, so it's best to cut them out.

  Generally the sprouts are cut off because that area as well as any green area can be toxic. Ptomaine can be produced in potatoes that turn green. If left in light, potatoes turn green. The green should be thoroughly trimmed away.

  I don't know about the sprouts, but potatoes do contain toxic glycoalkaloids. Cooking helps reduce them, as does selective breeding. If they are sprouting due to light exposure, that's a hint that toxicity might be higher. Greening is another hint. The guideline is to keep them in a cool, dark place. Refrigeration isn't necessary.
