Consumers should avoid buying or eating potatoes that show signs of sprouting, greening, physical damage or rotting since glycoalkaloids are not decomposed by cooking.

Glycoalkaloids are concentrated in the peel and prolonged exposure of tubers to light will stimulate the formation of glycoalkaloids near the surface of the potato tuber. Glycoalkaloids are not broken down by cooking or frying.
