INTRODUCTION: Delayed anaphylaxis following red meat consumption is a novel phenomenon in the Southwestern United States. This presentation will illustrate a case of IgE mediated activity against the galactose-α-1,3-galactose (alpha-gal) epitope. This carbohydrate determinant is common in humans and isotope switching to alpha-gal IgE occurs following ectoparasite exposure. First described in 2009, early case reports led to identification of the Amblyomma americanum, or lone star tick, as the sensitizing exposure. We present the first reported case of anaphylaxis in New Hampshire from red meat consumption following alpha-gal sensitization.
