EIA Confirmed in Tennessee and Alberta Horses


The Equine Disease Communication Center recently reported confirmed cases of equine infectious anemia (EIA) in horses from Shelby County, Tennessee, and Sturgeon County, Alberta, Canada.

Tennessee EIA

The Tennessee state veterinarian confirmed that three horses have tested positive for equine infectious anemia at a stable in Shelby County. Eleven other horses were exposed. There is an official quarantine.

Alberta EIA

The Canadian Animal Health Surveillance System reported a positive equine infectious anemia test from the Canadian Food Inspection Agency’s (CFIA) national reference laboratory for a horse located on a premises in Sturgeon County, Alberta.

The horse had been tested by an accredited veterinarian at the owner’s request because it was exhibiting clinical signs compatible with EIA infection. It died shortly after being sampled.

A CFIA investigation is underway, and movement controls were placed on the on-premises contact animals as per program policy. Initial reports indicate there are other equines on the affected premises.
