The Pennsylvania Department of Agriculture announced April 20 the quarantine of an equine barn in Halifax, in Dauphin County, after a horse at the barn tested positive for equine infectious anemia (EIA) on April 18.

There are 19 other horses quarantined on the premises as part of the quarantine order. The EIA-positive horse had a routine health check, which included a Coggins test for EIA, less than a week after the horse moved from another barn elsewhere in Dauphin County.

The horse was stabled previously at a farm in Williamstown, where another 13 horses are also under quarantine. The department is in the process of tracing the positive horse’s movement history.

The barns and horses are quarantined for at least 60 days. The quarantine can be lifted after the remaining horses are determined not to be infected
