FAQ
Question: 

There are white, raised spots on my potatoes. Why?

Answer: 

The white, raised spots on your potatoes are probably swollen lenticels due to wet soil conditions.  Potato tubers are enlarged underground stems.  Lenticels are small openings in the tuber surface that allow for gas exchange.  Saturated soils may cause the lenticels to swell as gas exchange is impeded. Affected potatoes may not store as long as normal, but are perfectly safe to eat.
