Japanese Encephalitis Confirmed in Goulburn Valley Pig Herd
February 11, 2025
Agriculture Victoria has announced the detection of the Japanese encephalitis (JE) virus in a Goulburn Valley pig herd. This marks the first case in a pig since April 2022.
Understanding Japanese Encephalitis
JE is a mosquito-borne viral disease that can lead to severe neurological issues in both animals and humans. The virus belongs to the Flavivirus genus and spread through a complex cycle involving mosquitoes, birds, and various other animals, including pigs and horses.
No Quarantine or Movement Restrictions Implemented
According to Agriculture Victoria, the detection is not unexpected given that the JE virus is considered established in mainland Australia. Therefore, no quarantine or movement restrictions are in place.
“We are actively monitoring the situation and conducting tests on pigs and other livestock displaying symptoms consistent with JE,” said Deputy Chief Veterinary Officer Sally Salmon.
Preventing Infection in Pigs
To safeguard your pigs from Japanese encephalitis, the department suggests reducing mosquito habitats in the vicinity and limiting exposure to mosquitoes. Proper management of water sources and areas prone to stagnant water can significantly reduce mosquitoes.
Human Health Guidelines
Earlier in January, a human case of Japanese encephalitis was confirmed in a resident of northern Victoria. There is currently no specific treatment available for the disease. Preventing mosquito bites is the best line of defense.
- Wear light-colored, loose clothing
- Apply insect repellent with DEET or picaridin
- Maintain your garden and remove stagnant water
Vaccination for High-Risk Groups
The JE virus vaccine is available free of charge for individuals in certain high-risk areas, including those in 24 specific local government areas in northern Victoria. Additionally, it is provided to those at occupational risk across all of Victoria.
Eligible groups include people who work in piggeries, abattoirs, and those living in high-risk local government areas.
How to Report Suspected Cases
JE remains a notifiable disease in Victoria. Anyone who suspects an animal is showing signs of Japanese encephalitis must report it within 12 hours. Here’s how to report:
- Contact your local veterinarian
- Call the 24-hour Emergency Animal Disease Hotline: 1800 675 888
- Use the Notify Now app
- Contact Agriculture Victoria animal health staff
