The Maryland Department of Agriculture (MDA) has reported that blood and nasal swab samples from a 2-year old filly in Laurel Park’s Barn 1 have been confirmed positive for neurologic equine herpesvirus type-1 (EHV-1) through testing performed at the University of Kentucky.

No other horses in Barn 1 are showing signs of EHV-1. Samples taken from five additional horses in the same barn are negative for EHV-1, as ascertained by the MDA’s Animal Health Diagnostic Laboratory in College Park. Samples from two other stablemates have been taken and results are pending.

“We have tested the four horses in the barn that are known to have left the state and returned in the past 10 days and all are negative,” said State Veterinarian Guy Hohenhaus, DVM. “This is positive news for us, for horsemen in other states and for our state veterinary colleagues with whom we are working closely.”

The MDA placed Hold Order was placed on Barn 1 at the central Maryland track Nov. 12, restricting all movement into and out of the barn, pending further testing. The Maryland Jockey today announced that until further notice no horses will be allowed to ship into Laurel Park except those coming from the Bowie Training Center on a Maryland Jockey Club shuttle.

Regular updates regarding this investigation will be available on MDA’s Web site.
