Western Australia Detects Another Suspected Bird Flu Case
A fifth suspected or confirmed case of highly pathogenic avian influenza H5 has been identified in Western Australia, officials confirmed. This latest development brings the total number of detections across Australia to five. Two cases have been definitively confirmed in migratory seabirds within Western Australia, and one confirmed case was previously identified in South Australia.
The new suspected instance was discovered at Roses Beach, located near Esperance. Further testing is underway to confirm the presence of the virus. This follows another suspected case near Dunsborough that was announced earlier in the week.
No Evidence of Local Wildlife Transmission
Western Australia’s Minister for Agriculture, Jackie Jarvis, stated that current evidence indicates no transmission to local wildlife populations. “There have been no detections in poultry, and there have been no reports of large scale mortalities,” Minister Jarvis reported. Her comments aim to reassure the public regarding the spread of the virus.
Regarding the Roses Beach discovery, Minister Jarvis explained, “A member of the public reported five [giant] petrels on Roses Beach [near Esperance] on Sunday 21st of June.” She added, “Only one of the petrels has returned a suspected positive result for bird flu. The other four birds returned negative results.”
“This is encouraging — it means there is no evidence of disease transmission here on the Australian mainland,” Minister Jarvis emphasized, highlighting the preliminary positive signs from the additional negative tests.
Samples Sent for Advanced Testing
Samples collected from the petrel found near Esperance, identified as a species common to the subantarctic region, have been dispatched to the Commonwealth Scientific and Industrial Research Organisation (CSIRO) for comprehensive analysis and confirmation.
