If you’ve left a bag of potatoes sitting around for a while, you might have noticed them starting to grow green, white, or somewhat purple sprouts. That’s the potato trying to grow into a new plant.
The sprouts themselves, as well as any green part of the potato, are home to a toxic alkaloid called solanine and must be removed. Eating them will make you sick – the National Library of Medicine even has a page on their website devoted to potato plant poisoning [http://www.nlm.nih.gov/medlineplus/ency/article/002875.htm] – though it would take quite a few to do it. The solanine gives the potato a bitter taste, so it wouldn’t be worth eating anyway.
As long as the sprouted potatoes are still firm and haven’t started to shrivel up, there’s no reason to throw them away. Once the sprouts and any green part of the potato have been removed, it’s safe to eat.
You can also plant your sprouted potatoes, though “The Vegetable Gardener’s Bible” by Edward C. Smith recommends using seed potatoes (which are available from garden supply stores and were grown for the express purpose of being planted) rather than supermarket potatoes for gardening.
To inhibit sprouting and keep your potatoes in their best condition, store them in a cool, dark, dry place with ample ventilation.
