Australia is checking for any sign of “entrenched” H5 bird flu in its wildlife after detecting the country’s first two cases, the government said Monday.<\/p>\n\n\n\n
Scientists confirmed at the weekend they had found the disease in a migratory sea bird, a brown skua, in remote Western Australia.<\/p>\n\n\n\n
Tests from another sick bird in the same area, a giant petrel, have now verified that it also had the H5 strain, officials said.<\/p>\n\n\n\n
Over the next three to seven days, experts will investigate whether the virus strain has spread further by boosting surveillance and testing, said Agriculture Minister Julie Collins.<\/p>\n\n\n\n
“We want to see whether or not there has been an entrenched infection in the wildlife in Australia,” she told a news conference.<\/p>\n\n\n\n
Australia was previously the only continent with no detections of the H5 strain, which can kill large numbers of poultry and wild birds.<\/p>\n\n\n\n
The country’s poultry and agricultural systems are free of H5 bird flu and there is no evidence of mass mortalities in wildlife, Collins said.<\/p>\n\n\n\n
Experience in other countries showed the H5 virus was hard to eradicate from farms and could be “devastating” to wildlife, she said.<\/p>\n\n\n\n
“Let me reiterate, at this stage we’re talking about two birds on an isolated beach,” the minister added.<\/p>\n\n\n\n
“We have had those two confirmed. We are yet to establish whether or not it’s entrenched in Australian wildlife.”<\/p>\n\n\n\n
Environment Minister Murray Watt said the variant’s spread to Australia was disappointing but “not unexpected”.<\/p>\n\n\n\n
“We only have two confirmed cases but we don’t underplay the threat that this poses to wildlife and our agriculture sector in Australia, should this become a wider outbreak.”<\/p>\n\n\n\n
The H5 strain has caused severe disease and high death rates in poultry and wild birds, and affected mammals across the globe.<\/p>\n\n\n\n
The wild birds most affected by the H5 strain include waterfowl, shorebirds, seabirds and birds of prey.<\/p>\n\n\n\n
Marine mammals have also been affected, with some detections in other animals such as cats, goats, alpacas and pigs.<\/p>\n\n\n\n
There has been concern that the deadly disease could add to the extinction risks faced by Australian fauna, many of which are unique to the vast continent.<\/p>\n\n\n\n
Almost half of Australia’s wild bird species, and 83 percent of its mammals, are found nowhere else.<\/p>\n\n\n\n
Scientists said last week the H5 bird flu strain had killed more than 13,000 elephant seal pups after infecting a breeding colony on the remote Heard and McDonald Islands, one of Australia’s external territories in the sub-Antarctic<\/p>\n","protected":false},"excerpt":{"rendered":"
