What are the GREY spots in potatoes?
Similarly one may ask, are GREY potatoes safe to eat?
After peeled or grated potatoes are exposed to air they will begin to turn gray or brown. This appearance can be off-putting, but the good news is that the quality of the potato isn't compromised. This is a harmless natural reaction and it is perfectly fine to cook and eat potatoes even if they have turned gray.
Subsequently, one may also ask, is it safe to eat potatoes with black spots?
These spots are called internal black spot and are essentially bruising that occurs from the potatoes lying against each other for an extended period of time. The potatoes are still safe to eat, just cut the spots away. If there is an extensive amount of Fusarium, this can give the potatoes an off flavor.
Potatoes Small White Spots – Lenticels Happily these small white spots on potatoes are not a reason for great concern. They are actually swollen lenticels caused by too much water. Lenticels are minute organs used by the tuber to breathe but in waterlogged soils they become blocked and swell up.
