What are the black spots on skin of potatoes?
The potatoes I bought have small, dark spots all over the skin. Potatoes have small holes in their skins called lenticels. These are actually the orifices through which the tubers respire, or breathe. Excess moisture can cause the lenticels to swell. Then, when they shrink back to normal size, they become discolored.
Is it OK to eat potatoes with brown spots?
This should not be a worry to humans though, as the virus/fungus isn’t harmful to us. All in all, the brown areas of tuber tissue are not harmful
Is it safe to eat potatoes that have mold on the outside?
Foods like these, as well as turnips, potatoes, and bell peppers, are still safe to eat as long as you remove the moldy spot and an inch or so all the way around it.
