Poland has reported an outbreak of highly pathogenic H5N1 avian influenza, commonly called bird flu, on two poultry farms near the German border in the northwestern part of the country, Reuters reported, citing the World Organisation for Animal Health (WOAH).

The two outbreaks were found on farms near the city of Szczecin and killed 22,900 poultry out of a total of 104,165 birds, with the rest of flocks culled, the Paris-based body said, quoting information from Poland's health authorities.
