Four more quarantines imposed on some Florida horse farms after equine herpesvirus-1 (EHV-1) was detected in a horse previously stabled at the Horse Shows in the Sun (HITS) facility in Ocala, have been released, according to a March 20 statement from the Florida Department of Agriculture and Consumer Services (FDACS).

Officials placed the HITS showgrounds under quarantine Feb. 27 after several horses connected to the facility tested positive for EHV-1. Two of the seven developed neurologic signs and were treated at the University of Florida’s College of Veterinary Medicine. The remaining five horses were quarantined at their home farms. Additionally, the FDACS quarantined several other facilities housing horses exposed to the disease while at the showgrounds. The FDACS stated that all EHV-1 quarantines would remain in effect for a minimum of 21 days from the last exposure.

In early March and after the appropriate length of time, disease testing began and officials released quarantines if farms met release protocol, the statement said. The following facilities connected to the HITS outbreak have been released from quarantine:

• POD-F Farm, Wellington (released March 9, 2013)
