Two barns at Parx Racing are under quarantine as a result of a positive test for equine herpesvirus, officials said Nov. 13.
The horse in question is trained by Steve Klesaris, who stables in Barn 21. Several other trainers have horses in the barn; none are permitted to train.
Barn 34 is under quarantine because a horse from Barn 21 was recently claimed and moved there. Parx officials said testing on that horse is under way, but in the meantime no horses from that barn will be permitted to train.
In addition, a pony barn was quarantined pending test results on a sick horse.
Parx is following customary quarantine procedure. Horses won't be permitted to leave the Pennsylvania racetrack unless it's an emergency, and any horses that ship to Parx won't be permitted to enter the grounds until the quarantine is lifted.
The general quarantine period for EHV-1 is a minimum of 21 days. Other tracks in the region have been notified of the situation, officials said.
Parx officials said horses that planned to ship in for racing Nov. 16-17 will be scratched with no penalty. Those programs were drawn earlier in the week.
Two $75,000 South Carolina residency stakes—the Donna Freyer and Christopher Elser Memorial—scheduled for Nov. 17 will be raced Dec. 28, officials said.
