Mango Reaction: Diarrhea, Ulcers - Costco, Hounslow England

Hayes Road, Hounslow, UB2 5XJ England, United Kingdom

Mangoes grown in Mexico. I have had uncontrollable diarrhoea and severe gum ulcers since I consumed just one slice on Sunday (I assumed it was from the roast I had as I cannot normally eat cooked food marinated in yoghurt). I then bought another box) just a day later from which I ate one slice on the Wednesday and I have been unwell since then, it is now Friday. Usually I am able to eat dried mango and Pakistani mangoes and even mango pulp so I am surprised I had a reaction to these, perhaps it's a chemical used as a pesticide causing this? | Symptoms: Diarrhea
