The outbreak was said to have come from a horse that came from the Meadows Racetrack and Casino in Washington, Pennsylvania.
On Thursday, state officials said that all horses that previously tested positive for the virus were retested on Feb. 20, and those came back negative.
The quarantined horses at the Warren County Fairgrounds and other facilities will be released on March 6, if no new cases are found.
Horses cannot be moved from the quarantined locations until released.
State officials emphasized that it is “very important that the owners continue to follow the strict bio-security measures, as the virus can spread through the air or by contaminated clothing and equipment.”
The ODA expects owners to follow the strict guidelines until March 6 and still expect precautionary measures even after quarantine is released.
