A THIRD horse has died from Hendra virus at a property near Macksville.
NSW Department of Primary Industries (DPI) confirmed the case on Monday after a private veterinarian took a swab from the dead horse and sent the sample to the DPI for laboratory analysis.
NSW Acting Chief Veterinary Officer, Dr Therese Wright, said the results confirmed the Hendra virus.
"The horse was noticeably ill on Thursday and was showing neurological changes, including loss of balance and staggering," Dr Wright said.
"The property has now been quarantined and a second horse on the property has been vaccinated, sampled and will continue to be monitored by a Livestock Health and Pest Authority (LHPA) veterinarian.
"DPI, LHPA and NSW Health are now working with the property owners."
Dr Wright said the 18 year-old mare was unfortunately not vaccinated against the Hendra virus.
