A total of 232,000 chickens and 1,000 turkeys have been culled at two Czech poultry farms due to an outbreak of the highly pathogenic H5N1 avian influenza virus. The larger farm, in Brod nad Tychou, is currently undergoing the destruction of 2.5 million chicken eggs. This outbreak marks the most severe case of bird flu in the Czech Republic to date. Additionally, a nationwide ban on poultry walking has been in effect since mid-December to prevent human contact with the virus.
