Australia issued a warning on Monday about the potential spread of H5N1 bird flu following an incident where around 50 greater crested terns were found dead off the coast south of Adelaide. This marks the first significant mortality event among seabirds in the country.
While there have been no reported cases of the virus on Australian farms, many have implemented strict measures to protect their poultry since the initial detection in June. Agriculture Minister Julie Collins confirmed the presence of H5N1 bird flu in a group of 49 deceased and 35 sick terns discovered through helicopter surveillance near Cape Jaffa, approximately 250 kilometers from Adelaide.
Collins mentioned that Australians should prepare for more cases and a higher number of wildlife being impacted by the virus. She stated that this incident represents the first confirmed mass mortality event due to H5N1 bird flu in the wildlife and natural environment, indicating inevitable significant losses.
Australia has recorded a total of 74 confirmed cases, with infections spread across Western Australia and Queensland, although the majority are concentrated in South Australia. Both Australia and New Zealand have been proactive in preparing for the virus, implementing stringent biosecurity measures on farms, conducting tests on shorebirds, vaccinating vulnerable species, and developing response plans.
Over the years, H5N1 bird flu has resulted in substantial losses for poultry farmers globally, affecting hundreds of millions of birds and mammals. Although the virus can infect humans through contact with infected animals, the worldwide number of cases remains low, and health officials assert that the risk to humans is minimal.
