"Most people want to avoid having the reaction, so they try to stay away from the food that triggers it." Cases of the bizarre allergy are cropping up in areas ripe with lone star ticks, according to research presented today at the American College of Allergy, Asthma and Immunology annual meeting in Anaheim, Calif.
