Potatoes are grown with a lot of pesticides and fungicides throughout the growing and harvesting seasons. I find it ironic that they want to engineer out the cancer causing chemical naturally found in the potato but continue to use very harmful chemicals to grow them. Potatoes are one of the vegetables that you should spend a bit more on and buy organic. Conventionally grown potatoes have a high residual level of pesticides in them.

Prior to cooking your potatoes, soak them in water for a while. This will remove a good portion of the naturally occurring toxic chemicals. My grandmother always soaked her potatoes before cooking.
