The location of the dead swan was on the shores of the Sava River in southeast Zagreb last weekend. Tests confirmed that the dead bird had contracted the H5 type of bird flu virus, but test findings as to whether it was the lethal H5N1 strain would be released on Sunday or Monday. This info was given by Mladen Pavic, spokesman for the Croatian agriculture, Forestry and Water Management Ministry.
In late February in 2006, the disease struck the country's southern coastal region, where two dead swans were tested positive for H5N1.
A series of precautionary measures to curb the spread of the disease were immediately taken by the authorities, including ordering farmers to keep their poultry indoors to try to prevent them from contracting the virus from wild birds.
