Minnesota Haflinger Mare Diagnosed with Equine Infectious Anemia

A 28‑year‑old Haflinger mare in Benton County, Minnesota has tested positive for equine infectious anemia (EIA). The horse was acquired from a riding‑camp herd dispersal in February and had no prior Coggins test. The new owner had the mare screened during routine spring vaccinations, after which it was placed under strict quarantine.

A trace investigation is underway, with preliminary findings indicating that 63 other horses may have been exposed. EIA is a viral disease transmitted through bodily fluids, blood‑feeding insects such as horseflies, or contaminated needles and equipment. There is no vaccine or cure; infected horses remain carriers for life and must be kept at least 200 yards away from uninfected equids.

The Equine Disease Communication Center (EDCC) is disseminating information about the outbreak and advising horse owners on testing and containment measures.
