Officials confirmed three EIA cases in horses from Kaufman, Tarrant, and Tom Green counties.

The horse, from the municipal district of Bonnyville, had been sampled by an accredited veterinarian to comply with U.S. import conditions

An investigation is ongoing, but this case appears to be unrelated to two other confirmed cases of EIA in Colorado this year.

The Wyoming Livestock Board completed the 60-day post-exposure tests on 61 equids residing at 12 premises in eight counties. All test results were negative.

The Georgia Department of Agriculture confirmed three EIA cases in Lamar County in August.

The affected horse from Bonnyville, Alberta, Canada, had potential exposure to EIA and, at the time of testing, was exhibiting clinical signs compatible with EIA infection

The newly confirmed positive horse’s home premises in Weld County has been quarantined and other resident horses will be retested in 60 days.

Since June, three Dallas County horses have tested positive for 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.

More than 100 of those horses were sent to 20 other states across the country. The Colorado Department of Agriculture is working to locate, quarantine, and retest those horses.

The Wyoming Livestock Board quarantined the additional premises after resident equids were exposed to a Colorado horse that ultimately tested positive for EIA.

The affected horse has been isolated from the remaining horses on the Weld County facility. The exposed horses will be observed and retested in 60 days.

A horse that recently traveled from Colorado to Wyoming and back again has tested positive for equine infectious anemia (EIA), prompting the quarantine of 41 exposed Wyoming horses.

Veterinarians identified the positive horses, from Lamar County, through surveillance for an EIA trace initiated in another state.
