| Toxicity Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. This poison affects the nervous system, causing weakness and confusion. .... Cooking at high temperatures (over 170 °C or 340 °F) partly destroys these. .... Glycoalkaloids may cause headaches, diarrhea, cramps, and in severe cases coma and death. |
| the State Extension Specialist for Food Safety at the University of Missouri notes that no reported cases of potato-source solanine poisoning have occurred in the U.S. in the last 50 years |
