Biosecurity Queensland has advised that Japanese encephalitis virus (JEV) has been detected in commercial pigs in Queensland.
This follows earlier detections in a person and in commercial pigs in May and a detection in a feral pig in June.
JEV circulates between mosquitoes, birds, and pigs, and should be considered a potential risk when mosquitoes are present.
A Biosecurity Queensland spokesperson said an increase in mosquitos was expected as the weather warms.
“Producers should include mosquito management as part of their biosecurity planning,” the spokesperson said.
JEV is a reportable disease in Queensland.
Anyone who suspects an animal is showing signs of JEV should report it to Biosecurity Queensland on 13-25-23.
JEV causes reproductive losses in pigs and neurological symptoms in horses, including incoordination, difficulty swallowing and impaired vision.
Humans can catch catch JEV, but only from mosquitos. It cannot be transmitted from infected animals or from human to human.
People working with pigs, including those with small herds or pets, should take steps to control mosquitoes, avoid exposure to mosquitoes and get vaccinated against JEV.
