ALBANY, Calif. (Mar. 26, 2019) — A 3-year-old filly at Golden Gate Fields was euthanized on March 23 after developing severe neurological signs. She has tested positive for equine herpesvirus-1 neurotrophic strain (EHV-1N). California Department of Food and Agriculture (CDFA) veterinary personnel have inspected the barn and reviewed biosecurity procedures that had been put in place. One barn of exposed horses has been placed under restricted quarantine with enhanced biosecurity measures and twice daily temperature monitoring. In addition to California Horse Racing Board (CHRB) and Golden Gate Fields management, CDFA personnel will continue to monitor the situation. Horses have resumed entering and leaving Golden Gate.
At this time, there is no indication of additional cases. The most common incubation period after EHV-1N exposure is three to eight days.
Any questions should be directed to CHRB Official Veterinarian Dr. Forrest Franklin or Equine Medical Director Dr. Rick Arthur. Biosecurity information is available on the CHRB and CDFA websites.
Updates will continue to be posted in the official veterinarians’ office and on the following websites:
