The tick that makes people allergic to red meat is in D.C.

Our recent warm weather has reawakened ticks, and one type in particular is becoming more common in the D.C. area: the lone star tick. One bite from this tick, which is easily identified by the white spot on its back if it’s a female, can cause a life-long adverse reaction to eating red meat.
Unlike the black-legged (deer) tick, the lone star tick doesn’t transmit Lyme disease, but it can produce a severe food allergy in people known as alpha-gal syndrome, which is an allergy to red meat.
