Video Dead birds turning up on Florida beaches sparks fresh warnings about avian flu A number of dead birds have been found on Florida beaches sparking fresh concerns about avian flu. (Credit: Fox Orlando) The first case of H5N1 bird flu has been confirmed in Australia, meaning the virus has now found its way to every continent. The Australian Department of Agriculture, Fisheries and Forestry said the virus was found in a single seabird, a brown skua, near Esperance on the south coast of Western Australia, in Cape Le Grand National Park. Australia’s Department of Primary Industries and Regional Development said it was "responding as part of a nationally coordinated plan with the Australian Department of Agriculture, Fisheries and Forestry and stakeholders across to reduce the impact of this disease." The outbreak in the U.S. has left millions of birds dead and has caused grocery store hikes and shortages, most notably with eggs.

Jackie Jarvis, Western Australia’s agricultural minister, said in a press conference on Friday: "As a result of WA’s established early detection system, appropriate action was taken, including isolating the bird and collecting samples for testing."

We are pleased to see the surveillance, and reporting system working as intended, with the bird reported through to DPIRD for further investigation."

Last year, around 13,000 of a population of 17,000 elephant seal pups died there in just a few months after being exposed.

A second case of another migratory bird is also suspected near Esperance.
