That’s why it’s best to monitor the appearance of the potatoes you’re storing.

Most people will just experience mild gastrointestinal upset."

Generally, poisoning from toxic potatoes can be treated at home.

“These natural chemicals are not removed by frying, baking, microwaving or boiling,” Stolbach says.

“Cutting off the sprouts and green skin will decrease, but not eliminate, your exposure.”

Keep potatoes in a cool, dark and well-ventilated place, such as a pantry or cabinet.

This is also why pre-washed potatoes will not last as long after you buy them.

The Bottom Line

Potatoes can be a healthy, tasty part of a varied diet.

Store potatoes in a cool, dry, dark place to prevent sprouting and premature spoilage.
