Barn 26, a 50-horse barn at Turfway Park, remains under quarantine after a 3-year-old filly who tested positive for the equine herpesvirus (EHV-1) was euthanized on Friday (Dec. 23). The Chuck Simon-trained filly, Coupe Aux Marrons, began exhibiting signs of the neurological disease last week and was shipped from Turfway to Hagyard Equine Medical Institute in Lexington, Ky., on Wednesday (Dec. 21).

According to Robert Stout, DVM, Kentucky state veterinarian with the Department of Agriculture, there is only one case (Coupe Aux Marrons) of equine herpes where clinical signs confirm the manifestation of the disease’s neurological form. However, based on blood samples analyzed at the University of Kentucky Livestock Diagnostic Center in Lexington, other horses housed in Barn 26 have been exposed to the virus.

None of the other horses who have tested positive for the presence of the virus exhibit any clinical signs of the neurological manifestation of the virus.

“At the current time, other horses in Barn 26 who may have been exposed to this virus are not exhibiting clinical signs of EVH-1 infection,” Stout said. “We have reports that each of those horses appears to be in satisfactory condition with no negative effects resulting from exposure
