Polish lab confirms third case of H5N1

A third wild swan in Poland has tested positive for the H5N1 strain of bird flu, a lab announced today.

The swan was found dead Saturday in Torun, about 120 miles north-west of Warsaw, the same place where the first two cases were detected and announced yesterday.

Tests showed that “we have a third case of H5N1”, said Tadeusz Wijaszka, director of the National Veterinary Research Institute in Pulawy, where the tests were conducted.

Samples were being sent to a European Union lab in Britain for further tests.
