According to a posting on ProMED Mail, Dr. Bogdan Konopka, Chief Veterinary Officer for the Ministry of Agriculture and Rural Development in Poland, notified the World Organization for Animal Health of an outbreak of H5N8 avian influenza, reported on November 23rd and confirmed the following day.  The outbreak occurred near Wronlawy in the Province of Wielkopolskie.  Wronlawy is approximately 50 miles east of the border with Germany.  The farm held 924,000 hens, of which 119,000 died with the remainder depopulated.

The official report did not provide a source of the outbreak, but is presumed to be from migratory waterfowl consistent with concurrent outbreaks in eastern and western Europe.  During 2020, a number of outbreaks have been reported by Poland with increasing frequency.
