Contagious equine metritis probe involves 45 states
10 positive stallions, 433 CEM exposed horses undergo treatment


"Though never expecting to identify a foreign animal disease in a population of horses such as this, the Kentucky Department of Agriculture, under leadership of Commissioner Richie Farmer, has spent considerable time and effort in planning for the unexpected," says Ford. "This event demonstrates the efficacy of this planning and preparation."

"The (Kentucky) farm should be commended. The owners and staff have been very transparent, and worked well with the government and their clients. Had they not done so, we might have seen a much worse situation," Linda Mettel, a veterinarian at the New York State Animal Health Diagnostic Center at Cornell University's College of Veterinary Medicine, tells DVM Newsmagazine.

Still, veterinarians and anyone else who handles breeding mares or stallions, should follow strict hygienic practices, Mettel says.

She issued a news release listing basic practices that should be observed to help prevent the spread of CEM or other infectious diseases.

The United States has been considered free of CEM since the late 1970s. It is reported in about 25 other countries. The disease usually causes temporary infertility and, in rare cases, abortions. It is transmitted during breeding or through artificial insemination.

CEM is treated with disinfectants and antibiotics. CEM-positive mares, and mares imported from CEM-postive countries, must undergo treatment and remain in quarantine at least 21 days. Stallions infected with CEM or come from such countries must be quarantined throughout a full treatment regimen and then test negative for the disease.

In Kentucky, prior to a stallion's being declared free of the disease, it must undergo a test breeding process that calls for two mares to be bred, then cultured and test negative twice, Ford explains.

"Our investigation so far has found no evidence that the disease spread outside the identified populations; thus this event will have no effect on our signature Thoroughbred industry or the 2009 breeding season," he says.
