No evidence that nut allergens spread through aircraft ventilation systems
There is no evidence for the commonly held belief that nut allergens can be spread through aircraft ventilation systems, according
to a new study. It found that surface residues pose the main risk, likely heightened by fast turnarounds of many low-cost
carriers. This is according to allergy and aviation medicine specialists in an evidence review published in the Archives of
Disease in Childhood. Around 2–3 per cent of children and 1–2 per cent of adults in the UK have a food allergy.
