Most food allergies are manifest following ingestion. Which food allergic reactions have been documented to occur as a result of inhalation? What clinical manifestations are commonly associated with inhalation-induced allergic reactions?
According to the cited reference “….published reports have highlighted the inhalation of allergens from fish, shellfish, seeds, soybeans, cereal grains, chicken eggs, cow milk, and many other foods….”. “Symptoms have typically included respiratory manifestations such as rhinoconjunctivitis, coughing, wheezing, dyspnea, asthma and anaphylaxis. In addition, there have been many published reports of occupational asthma following the inhalation of relevant food allergens.” (James JM and Crespo JF. Allergic reactions to foods by inhalation. 2007 Curr Allergy and Asthma Reports 7:167-174)
