KY Puts Restrictions on WI Stallions

Kentucky veterinary officials are now requiring that stallions coming from Wisconsin be tested for contagious equine metritis (CEM) prior to entering the state. The order, issued today by state veterinarian Robert C. Stout, stems from Kentucky's investigation into cases of CEM, which were first discovered in the state in December. This is the first official interstate movement restriction to result from the nationwide investigation, which includes 614 horses in 45 states.

Texas Testing 15 Horses Linked to CEM

Texas is among 27 states tracing and testing horses that may have been exposed to contagious equine metritis (CEM), a highly contagious disease that can be transmitted during breeding or artificial insemination. CEM can cause temporary infertility of horses. The disease, not known to affect humans, was first detected in the United States in 1978, then again in l979. In both instances, the infection was eradicated.

Details Revealed on KY CEM Case

State and federal agriculture officials announced Dec. 16 that a Quarter Horse stallion standing at stud in Kentucky has tested positive for contagious equine metritis.

Kentucky Breeding Regulations Amended

The Kentucky Department of Agriculture filed emergency regulations regarding testing procedures for contagious equine metritis (CEM) to be followed when breeding an imported mare in the state. These regulations require an extra pre-breeding swab of the endometrium, and will allow a stallion covering an imported mare to be treated and returned to service rather than waiting the previous 12-hour mandatory rest period.
