We have an over abundance of them this year, but on my third one I started breaking out- I thought I got into some poison ivy- nope it was the mangos! I have a nasty rash under my ring, the side of my mouth and a little in my eye. These were fresh off the trees and it is actually the sap/skin and the seed I am allergic too. I peeled the others with gloves and froze them in icecube trays for the rest of the family.
