Seven suspected new cases of deadly H5 bird flu have been reported in South Australia, with experts warning it is evidence of spread into Australian wildlife. All seven birds are greater crested terns, a common seabird, found along the Limestone Coast. This discovery follows two confirmed cases in the same species over the weekend, including the first positive detection in metropolitan Adelaide.
Evidence of Local Spread
BirdLife Australia’s chief executive, Kate Millar, said the outbreak is “now taking hold and is evidence of spread.” She compared the situation to a bushfire, noting that the initial cases in subantarctic birds were like embers, and now finding the virus in crested terns is “the smoke.” If the CSIRO verifies the suspected cases, the total in South Australia will rise to 14, with 10 in local greater crested terns.
Key Locations and Findings
The birds were discovered at three locations: one at Cape Jaffa, five around Southend Jetty near Beachport, and one at Port MacDonnell, just 20km from the Victorian border. Of the five at Southend Jetty, four were sick and one was dead. The birds at Cape Jaffa and Port MacDonnell were also dead. South Australia’s primary industries minister, Clare Scriven, called the development concerning.
| Location | Number of Birds | Condition |
|---|---|---|
| Cape Jaffa | 1 | Dead |
| Southend Jetty | 5 | 4 sick, 1 dead |
| Port MacDonnell | 1 | Dead |
Impact on Wildlife and Agriculture
So far, all detections have been in wild seabirds, with no cases in poultry or the broader agricultural industry. However, experts warn the virus could mutate and spread to other species. The state’s chief veterinary officer, Dr Skye Fruean, said it’s too early to determine if the Southend Jetty birds are part of a cluster. Government analysis of samples sent to the CSIRO will help clarify the local spread.
Key Takeaways
- Seven suspected H5 bird flu cases in greater crested terns in South Australia.
- Location cluster on the Limestone Coast, including near the Victorian border.
- Experts describe the situation as evidence of spread into local wildlife.
- No detections in poultry yet, but monitoring continues.
- CSIRO testing will confirm cases and help assess the outbreak.
FAQ
What is H5 bird flu?
H5 bird flu (H5N1) is a highly pathogenic avian influenza virus that can cause severe disease in birds and occasionally infect humans. It spreads through contact with infected birds or contaminated environments.
How is the virus spreading in Australia?
The virus is believed to have arrived via migratory subantarctic birds and is now being detected in local seabirds like greater crested terns, indicating it is becoming established in Australian wildlife.
Should the public be concerned?
The risk to the general public remains low, but people should avoid handling sick or dead wild birds. The government is monitoring the situation closely, especially for any potential spread to poultry farms.
