The Maryland Department of Agriculture has temporarily extended the hold order on Barn 9 at Laurel Park after two of the 36 horses stabled there did not clear the testing process for equine herpesvirus. Neither is showing symptoms of the virus, according to officials. In a late development Thursday, trainer Rodney Jenkins, who conditions all the horses stabled in Barn 9 at Laurel Park, has elected to relocate the two horses that did not clear the testing process to an isolated barn on the grandstand side of the Bowie Training Center. They will remain there pending negative test results. The two are to be re-tested at Laurel Park before being shipped to Bowie.Friday morning the Maryland Department of Agriculture is to lift the hold order on Barn 9, allowing the remaining 34 horses to resume normal activities. The Jenkins horses will be eligible to run March 8. The racing office takes entries for that card Friday. A filly stabled in the barn was euthanized Jan. 26.Meanwhile at Pimlico Race Course, four of the six horses in the detention barn tested negative for the virus in both blood samples and nasal swab tests and have been moved back to their original barns to resume normal activities. The two that did not clear are not showing symptoms of EHV-1 but are prohibited from mixing with the general horse population until they test negative.Last month, the Department Of Agriculture lifted the Hold Orders on Barns 5, 6 and A at Pimlico while the Maryland Jockey Club lifted its self-imposed quarantine, allowing horses from the legendary Baltimore track to compete at Laurel. Three horses from three different Pimlico barns were euthanized in January. The last clinical case of the virus at Pimlico happened Jan. 19. There have been no outbreaks at the Bowie Training Center where approximately 600 horses are stabled.
Equine herpesvirus causes upper respiratory infection and can also cause neurological disease.
