Dead birds found at four different locations in Hungary have tested positive for the bird flu virus, government spokesman Andras Batiz said Wednesday.

Batiz added that precautionary measures had been taken in Szazhalombatta, Dunaszentbenedek and Szentendre, while in Nagybaracska, where dead birds had been found earlier, the quarantine was underway.

Hungarian experts said the death of the birds, including a seagull, a wild duck and two swans, was caused by the deadly H5N1 strain. But official results are to be issued by the European reference laboratory in Weybridge, Britain.
