Two additional horses at Turfway Park, in Florence, Kentucky, have tested positive for equine herpesvirus-1 (EHV-1), Kentucky animal health officials said Feb. 6.

E.S. Rusty Ford, equine operations consultant for the Kentucky Department of Agriculture’s (KDA) Office of the State Veterinarian, said samples collected Feb. 5 from 26 horses stabled in the one quarantined barn at Turfway revealed two additional positive horses. This brings the total number of confirmed cases to three, including the index horse that tested positive last week and was euthanized. The remaining 24 horses tested negative.

“One of the horses identified as positive today is a 4-year-old filly who was positive on both nasal swab and in the whole blood buffy coat; the second positive, a 2014 gelding was positive only on the nasal swab,” Ford said. “Arrangements are underway for these two horses, along with a non-Thoroughbred pony in the barn to be removed from the backside and into isolation off the grounds.”

The quarantined barn has 24-hour guarded security with entry into the barn restricted to essential personnel only, Ford said. The KDA will continue to have personnel on the grounds and work with track management, horsemen, veterinarians, and racing officials to maintain a safe and healthy racing environment, he added
