As part of the ongoing effort to protect animal health, all equids entering the 100th Wyoming State Fair, taking place Aug. 11-18 in Douglas, must be accompanied by proof of a negative Coggins test, regardless of their state of origin. Coggins tests are used to detect equine infectious anemia (EIA).

EIA is caused by a retrovirus, and it is a chronic infection resulting in a lifelong carrier state with periodic exacerbations of anemic illness. There are no treatment options available and no preventive measures. Most affected horses are euthanized to prevent the spread of disease.

The requirements are in place this year as a result the Royal Canadian Mounted Police’s presence at the fair and the requirements placed on them to ensure they’re able to return to Canada.

In the past, horses originating from outside of Wyoming were required to present proof of a negative Coggins test. This year, all individuals preparing to enter state fairgrounds with equids will be required to present a copy of the negative EIA test at the animal health check in; this information must also be recorded on their certificate of veterinary health inspection. EIA testing is carried out only at USDA Animal and Plant Health Inspection Service approved laboratories and must be completed before arriving at the fair.
