Folks with peanut allergies don't have to worry that someone might be munching on the nuts during an airline flight, researchers report.

It’s widely assumed that flying poses a particular risk for those with nut allergies as the allergens can spread through the aircraft ventilation system, but a review of 40 years’ worth of scientific evidence has concluded that there’s no basis to this belief.

There is no evidence for the commonly held belief that nut allergens can be spread through aircraft ventilation systems, say allergy and aviation medicine specialists in an evidence review published in the Archives of Disease in Childhood.

Asking aeroplane passengers not to eat nuts is unlikely to prevent an allergic reaction mid-flight - but cleaning their seat with a wet wipe could, allergy specialists say in a review of the latest evidence.

Filters on commercial flights seem to stop peanut particles from circulating around aircraft, making the risk of a serious allergic reaction from inhaling the allergens very low

It’s not true that nut allergens can spread throughout aircraft in flight, researchers report. Peanut dust from shelling nuts occurs at very low levels and doesn’t tend to spr
