The symptoms of a peanut allergy can be fatal. The reaction primarily affects the respiratory system, causing a swelling of the air passages that makes it difficult for the victim to breathe. If the person has a severe sensitivity, he or she may die. Even a tiny amount of peanut dust in the air is enough to kill some peanut allergy sufferers. For this reason, peanuts are no longer served as snacks on airplanes, and many school cafeterias have become peanut-free zones.
