 Management is by avoiding eating the causal nuts or foods that contain them among their ingredients, and a prompt treatment if there is an accidental ingestion.Total avoidance is complicated because the declaration of the presence of trace amounts of allergens in foods is not mandatory in any country, with the exception of Brazil.Tree nut allergies are distinct from peanut allergy, as peanuts are legumes, whereas a tree nut is a hard-shelled nut.
