Mango
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).
