Contagious Equine Metritis Update

Late this spring a 23rd stallion in the United States was found to be infected with the contagious equine metritis-causing organism Taylorella equigenitalis, according to a news release from the Office of the (KY) State Veterinarian.

This 23rd stallion is located in Wisconsin and epidemiologically linked to the previous outbreak that traces to a Wisconsin facility, the release stated.

Available information leads the Office of State Veterinarian to conclude that stallions with a history of having been collected or used for breeding in Wisconsin (including imported stallions clearing CEM quarantine in WI) do pose identified risks of introducing the CEM-causing organism Taylorella equigenitalis to Kentucky.

In response to this identified risk, the Office of State (KY) Veterinarian will continue requiring that stallions entering Kentucky from Wisconsin for breeding purposes (live cover or collection) be cultured negative for CEM-causing bacterium and enter the state with an entry permit issued by the Kentucky Department of Agriculture.

The United States Department of Agriculture has undertaken and implemented a program to survey the U.S. breeding population (stallions) for the CEM-causing organism Taylorella equigenitalis. The survey is being conducted to define if the organism has prevalence or that the U.S. stallion population is apparently free of the organism.

Participation in the survey is voluntary with the USDA paying part of the associated costs.

The project is scheduled to conclude in August. Those interested should contact the USDA's Kentucky Area Office at 502/848-2040 for details.

Returning the U.S. to a CEM-free status will aide in resolving many of the restrictions and/or testing requirements currently imposed on adult breeding animals being exported, according to the Office of State (KY) Veterinarian.

The Kentucky Department of Agriculture appreciates the USDA initiative and effort to better define the CEM status of the United States equine population and encourages individuals to investigate the cost saving benefits recognized with enrollment of their stallion(s) in the USDA's CEM Survey. With the surveying scheduled to conclude in August, those with interest should contact the USDA Area Office immediately for enrollment information.
