As JE is considered established in mainland Australia, no quarantine or movement restrictions will be put in place.
Deputy chief veterinary officer Sally Salmon said the detection, which is the first since April 2022, was not unexpected.
“We are actively monitoring the situation and continue to investigate and test pigs and other livestock that exhibit clinical signs consistent with JE virus infection,” she said.
“You can help your pigs avoid infection by reducing nearby mosquito habitats and limiting their exposure to mosquitoes.”
Meanwhile, Gannawarra Shire Council announced free JE vaccinations for eligible residents on Tuesday, February 11.
Chief executive Geoff Rollinson said the shire’s environment increased the risk of mosquito-borne disease due to its many waterways and native wildlife.
Residents aged two months and older who live or work at properties with pigs, work in mosquito surveillance or control, or are going to high-risk areas for seasonal work are eligible for the free vaccination.
Those regularly spending time outdoors, experiencing homelessness, or living in conditions with limited mosquito protection are also eligible.
“If you have any questions regarding the Japanese encephalitis virus vaccine, please talk to your GP or call council’s immunisation team,” Mr Rollinson said.
The council recommends avoiding being bitten by mosquitoes through avoiding outdoor activity at dawn and dusk, wearing long, loose fitting clothes and applying mosquito repellent when outdoors.
Council-run immunisation sessions will be promoted via its Facebook page and at www.gsc.vic.gov.au/immunisation
