The Equine Disease Communication Center (EDCC) reported Sept. 17 that the Wyoming Livestock Board has quarantined an additional five premises as a result of resident equids being exposed to a Colorado horse that tested positive for equine infectious anemia (EIA).

No horses in Wyoming have tested positive for EIA at this time. However, there are now 58 horses quarantined at 12 facilities in Albany, Fremont, Laramie, Lincoln, Natrona, Park, Sweetwater, and Teton counties.

“The majority of these horses exposed at the Colorado facility were imported illegally to Wyoming,” the EDCC said. “It is important that all horse and other livestock owners are aware that the Wyoming Livestock Board (and all other states) have import requirements for animals entering the state. There are also federal requirements for animals traveling interstate. For horses entering Wyoming, a negative Coggins test within 12 months and a health certificate with the origin and destination noted issued by an accredited veterinarian within thirty days is required
