The Colorado Department of Agriculture, State Veterinarian’s Office, was notified by the US Department of Agriculture’s National Veterinary Services Laboratory (NVSL) that a Weld County horse tested positive for equine infectious anemia (EIA). The initial test result was received on August 24, 2018, with a re-test confirmation on August 28, 2018.
The Weld County facility is currently under a quarantine order that restricts movement of horses until further testing is completed by the Colorado Department of Agriculture (CDA).
“The affected horse has been isolated from the remaining horses on the facility, which will be observed and retested in 60 days. We are actively tracing movements of the horse and others it came in contact with in Colorado and other states. The disease is most commonly spread by biting flies and we’re still in the midst of Colorado’s fly season,” said State Veterinarian Dr. Keith Roehr.
