As of March 1, 2018, the Arizona Department of Agriculture has lifted the EHV-1 quarantine at Turf Paradise Racetrack in response to the case of equine herpesvirus myeloencephalopathy (EHM) that was discovered there.
Investigations were carried out to identify any other horses that might have been exposed to EHV-1. The state veterinarian and the Arizona Department of Gaming Division of Racing worked with officials at Turf Paradise to quarantine and monitor any other potentially exposed horses. No other EHV-1 cases were found.
During the quarantine and investigation, track management required strict biosecurity measures be practiced by all horse owners and other personnel.
