Wyoming Livestock Board

On Friday August 25th, the Wyoming Livestock Board was notified by the Colorado Department of Agriculture that a horse which tested positive in Colorado for Equine Infectious Anemia (EIA) had been moved to Sweetwater County Wyoming. While the horse was tested in Colorado, it was shipped prior to test results being read and reported and without an Interstate Certificate of Veterinary Inspection. The horse was returned to Colorado and subsequently Wyoming has quarantined 41 exposed equine on the premise where the horse had been prior to going back to Colorado. These equine were exposed to the positive Colorado horse for 6 days and will be tested initially on August 30th and again sixty days later. Another two exposed horses from the Colorado premises were shipped to Lincoln County with a negative EIA test. They will remain under quarantine and re-tested at 60 days. None of these equine are race horses.
