The Department of Agriculture, Water and the Environment is reminding producers to remain vigilant as more than 60 piggeries across four states battle Japanese encephalitis (JEV) outbreaks.
The virus remains of "significant concern", and state and federal biosecurity authorities have warned pig and horse owners that the zoonotic disease still poses risks to humans and animals.
Already this year, three people have died from the virus, and there are more than 60 piggeries with infected herds across New South Wales, Victoria, Queensland and South Australia.
Australian Chief Veterinary Officer Dr Mark Schipp says while the government is working towards vanquishing the danger, producers will need to continue to put precaution methods into practice.
"The best course of action is to try and avoid mosquito bites to yourself and your animals," he says.
"And part of that means reducing mosquito infestations."
The Department of Agriculture, Water and the Environment, in conjunction with key industry heads, continue to provide producers with updated information regarding Japanese encephalitis.
Those working with pigs, including those who may have a small herd or pet, have been advised to take steps that control mosquitoes, whilst continuing to implement effective biosecurity measures.
It is also recommended that those in care of horses put a hooded rug and a fly mask on their animals to reduce their exposure to mosquitos.
Severe cases of encephalitis, which means swelling on the brain, can be fatal to horses, and symptoms of infection include elevated temperature, jaundice, lethargy, anorexia, incoordination, difficulty swallowing, impaired vision, and lethargy.
In pigs, unexplained abortions or stillbirths remain the tell-tale sign of a potential outbreak.
