My Potatoes Were Green All the Way to The Center and Not Just the Skins.

Q:

My potatoes were green all the way to the center and not just the skins, which is common when exposed to sunlight. Are these safe to eat and how do I prevent this from happening in the future? As it happened to all the sizes, even the ones deep in the soil not exposed to the light.

A:

Are these potatoes you bought or grew? Potatoes on display at retail stores are even more susceptible to greening from fluorescent lighting.  If still in the bag, take back to the produce manager or store for a refund or replacement.
