Seventeen horses on a Kent County, Md., farm tested negative for equine herpesvirus-1 (EHV-1) on March 3, resulting in the March 4 removal of a Maryland Department of Agriculture (MDA) hold order that had prevented equine transport to and from the facility.

The hold order was enacted on Jan. 26, when the first of two horses at the farm were euthanatized due to the neurologic form of the virus. The final EHV-1 clinical sign on the farm was detected on Feb. 4.

Upon removal of the hold order, farm personnel and horses were permitted to resume normal activities
