New Cases of Bird Flu in Croatia, Britain

Croatian authorities have stepped up measures to deal with bird flu, following the discovery of a number of dead swans in a lake east of the capital, Zagreb

Agricultural officials began killing all poultry within several kilometers surrounding the lake Saturday, while tests are under way to determine if the swans were victims of the deadly H5N1 strain that has killed more than 60 people since 2003.

The European Union has barred poultry imports from Romania, Turkey and Greece after discovery of the virus in those countries. Romanian officials announced another case Friday near the border with Moldova, and Russia Saturday confirmed a case in the Ural Mountains (near Chelyabinsk).

British officials are urging the EU to ban imports of wild birds into the 25 nation bloc following a confirmed a case of bird flu in a parrot that had been imported from Suriname.
