Australia has confirmed its first detections of H5 high pathogenicity avian influenza (H5 bird flu) in wild birds. This marks the first time this global strain has been found in Australia. The risk to people in Australia is low, and the country is well prepared to respond if needed.
The poultry industry is preparing for the potential spread of the deadly H5N1 avian influenza variant after two confirmed cases in migratory seabirds. Industry bodies say experience with the previous H7 variant has given producers time to prepare.
Approximately 40% of Australia's egg-laying chickens are free-range. The free-range farming method, which allows chickens to roam outdoors, has been linked to higher risks of avian influenza transmission. The open environment increases the likelihood of contact between domestic poultry and wild birds, which can carry the virus without showing symptoms. This proximity heightens the risk of the virus being introduced into commercial flocks.
In response to the outbreak, the Australian government and industry bodies are implementing stringent biosecurity measures. These include monitoring wild bird populations, restricting the movement of poultry products, and enhancing surveillance in both domestic and wild bird populations. Farmers are being advised to increase biosecurity on their properties, including limiting access to poultry sheds and ensuring that equipment and vehicles are cleaned and disinfected regularly.
The risk to human health remains low, as human infections with avian influenza are rare. However, authorities advise the public to avoid contact with sick or dead birds and to report any such sightings to the Emergency Animal Disease Hotline.
The situation is evolving, and ongoing monitoring and response efforts are crucial to prevent the spread of avian influenza in Australia.
