A horse in Ocean County has been euthanized after contracting Eastern Equine Encephalitis.
It’s the third horse in New Jersey to be infected with the deadly disease in 2023.
The New Jersey Department of Agriculture closely monitors these cases of encephalitis in livestock.
Horses are infected with Eastern Equine Encephalitis through the bite of a mosquito.
State officials tell News 12 that in this case, the horse was an unvaccinated, 28-year old Grade-breed-mare.
The fatality rate among horses with EEE is 90%, according to the Department of Agriculture.
Two other cases of Eastern Equine Encephalitis were also found in southern New Jersey this year.
One in Gloucester County and the other in Salem.
There is a vaccine for livestock for both Eastern Equine Encephalitis and West Nile virus.
However, there is not a vaccine for humans who can also contract Eastern Equine Encephalitis.
In New Jersey, horse owners are required to report cases of encephalitis to the state within 48 hours.
