General poisoning notes:

Mango (Mangifera indica) is a tropical fruit that is seasonally available in Canadian food stores. The skin of the fruit and the petiole, by which the fruit is attached to the stem, contain oleoresins. These chemicals are cross-reactive to the catechols contained in poison-ivy plants and in other members of Rhus species that cause dermatitis. Humans who are sensitized and develop dermatitis from these plants should be cautious about touching the skin of mangoes. The shells of cashews (Anacardium occidentale) are also cross-reactive with catechols of Rhus species. However, cashews shells are removed before the nuts are sold in Canada (Kingsbury 1964, Geller 1989).
