Australia’s recent declaration of being bird flu-free has proved short-lived, with the Victorian Agriculture Department announcing an outbreak at a farm in the state’s north.
The Australian Centre for Disease Preparedness conducted testing at Geelong confirming a H7N8 strain, which is different to the strain that hit Victorian poultry farms last year.
The property has been placed in quarantine and arrangements made to ensure the disease does not spread from the Strathbogie Shire in Victoria’s north-east, the department said.
On Feb. 6, the federal government announced Australia was officially bird flu-free after there had been no detections of H7 avian influenza since July.
More than 1.8 million birds were killed in a quest to rid the nation of the disease after Victoria, New South Wales, and the ACT experienced outbreaks.
The Victorian Agriculture Department warned people should contact a 24-hour hotline, on 1800 675 888, or their local vet if they have any suspicions about possible bird flu cases.
