Investigation into EIA-positive horse in Colorado continues

Over 200 horses need to be located, tested across country

    The Colorado Department of Agriculture’s state veterinarian’s office is continuing their investigation into a Weld County horse that tested positive for Equine Infectious Anemia in late August.  
    With the help of records from CDA’s Brands Division and Rocky Mountain Regional Animal Health Laboratory, the state veterinarian’s office has determined that approximately 240 horses have been on the quarantined premises during the same time as the index positive animal.  
    Approximately 100 of these horses were sent to 20 other states across the country, and steps are being taken to locate, quarantine and retest those horses.
    At this time, no other horses have tested positive for EIA.
    “We are working to locate approximately 140 horses that went to different premises across Colorado. We are asking horse owners to contact us if they purchased horses in Weld County between July 18-Aug. 20,” said state veterinarian Dr. Keith Roehr. “We will work with owners to see if their horses came from the quarantined property. This is an important step in the disease investigation.”
