Ara h 2 is detectable on surfaces of commercial airplanes.

Peanuts are frequently served on commercial airplanes and have been the source of numerous self-reported allergic reactions. Small amounts of Ara h 2 were consistently detected on surfaces of commercial airplanes but not in air samples. Avoidance recommendations, such as wiping surfaces, will reduce inadvertent contact exposure to peanut in peanut allergic travelers.
