A recent research article was published in the Annals of Allergy, Asthma & Immunology addressing several common questions regarding food allergy avoidance. One myth the researchers, Egan and Greenhawt (2018), addressed was that a danger exists from inhalation of peanut dust or vapors from peanut-containing products. It is important to make the distinction between odors, which are organic compounds that are nonallergenic, and aerosolization of food allergens, which are proteins.
Researchers utilized air monitors which measured Ara h 1, a peanut component, in order to detect peanut protein. They we unable to detect any Ara h 1 in school cafeterias, sporting events, or commercial airlines where there are commonly peanut-containing products. Researchers also used this same testing technique in a household setting a found detectable levels only while peanuts were actively being deshelled. Levels dropped to undetectable levels immediately after deshelling stopped, indicating the particle does not remain airborne.
The evidence indicates, “…that inhalational exposures to peanut products are highly unlikely to trigger allergic reactions”.
