H5 bird flu strain detected in Australian seabird for first time
The H5 strain of bird flu has been detected in an Australian seabird for the first time, marking a concerning development for biosecurity. Authorities are conducting surveillance to determine if the virus spread from migratory birds to native populations.
Why it matters
The detection of H5 in native wildlife poses potential risks to biodiversity and agricultural biosecurity, necessitating enhanced monitoring.
The H5 strain of bird flu has been detected in an Australian seabird for the first time.
Previous confirmed cases have involved migratory birds from the sub-Antarctic region.
Agriculture Minister Julie Collins said lab testing by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) had confirmed the deadly strain in a greater crested tern found in Robe in South Australia's Limestone Coast.
There have also been two further confirmed cases in South Australia (SA) and one in Western Australia (WA), bringing the total number of detections to 12.
Collins said there was still no evidence of mass mortality among wildlife and no evidence of any spread to agricultural settings.
The minister said SA authorities were "implementing enhanced surveillance in the area where this bird was found", and that further investigation was being conducted to determine how the bird contracted the virus.
