A chitinase-like protein cross-reacting with latex has been found in mango as well as avocado, chestnut, banana, kiwi, tomato, passion fruit, and papaya. There is a panallergen found in celery, carrot, apple, peanut, paprika, anise, fennel, coriander, and cumin that demonstrates cross-reactivity with mango.

Mango contains a number of different allergens which are found in many other foods besides pistachio and cashew. Thus, although the exact incidence of reactions to mango remains unestablished, it is obvious that compared to other foods, reactions to mango occur less frequently. In another study carried out over nine years, in 580 patients with food allergy, mango was responsible for 6% of the foods to which patients reacted. For example, in a series of 132 children, ages 3 to 19 years, there was one case of mango allergy compared to cow's milk in which there were 11 cases (1).
