Victoria’s chief veterinary officer, Graeme Cooke, said the latest infected farm housed between 150,000 and 200,000 egg-laying chickens.
“This latest infected premises was once again picked up on very early surveillance and that means it can be dealt with very early,” Dr Cooke said.
A control zone is in place spanning approximately 100 kilometres from west to east across the region, covering six of the seven farms detected with the H7N3 strain of avian influenza.
“[Control measures] really reduce the level of virus in an area. The faster we can pick it up, the less risk there is of onwards spread,” Dr Cooke said.
“The requirements in the controlled areas, especially the restricted areas, are to prevent onward movement of the virus either by vehicles, people or other means.
“Meredith has consistently been detecting [bird flu].
“If this virus was allowed to spread onward it would be devastating for the rest of the poultry industry in Victoria and perhaps onward through Australia.
“The right thing to do is to stop the infected premises being any further risk, and that’s the action that is taken through the humane destruction and disposal and the onwards cleansing and disinfection of the farms.”
Agriculture Victoria is investigating the cause of the outbreaks but so far it is believed the disease has spread from wild birds into domestic poultry.
The state’s outbreak of avian influenza has also spread to a commercial duck farm near Meredith.
Australian Duck Meat Association CEO Greg Parkinson said the farm represented about two per cent of Australia’s commercial duck population and mostly supplied meat to restaurants, not supermarkets.
“Ducks are kept in sheds precisely for these sorts of reasons — we try to buffer ourselves from wild bird incursions and virus spillovers.
“About 30 million ducks are processed for meat per year.”
The infected duck farm does not supply either of these companies.
There are many types of bird flu, including the highly pathogenic H5N1 strain, which has been detected in Asia, Europe, the Middle East, Africa, North America, South America and Antarctica.
Australia’s response to eradicate avian influenza is in stark contrast to countries like the United States, where more than 96 million birds have been affected by the disease since an outbreak that began in 2022, according to the U.S Centre for Disease Control and Prevention.
