Poland: Avian Influenza Confirmed in Commercial Flocks

In Poland, the 2021/2022 wave of highly pathogenic avian influenza (HPAI) began on November 2, 2021, leading to 93 confirmed outbreaks in poultry through April 28, 2022, in 13 Polish provinces. The outbreaks were confirmed mainly in commercial flocks (83 farms) keeping slaughter ducks (33) and turkey (22). At the beginning of the second quarter of 2022, the HPAI situation in Poland appeared to stabilize, as the last outbreak in Poland was confirmed on March 9, 2022, despite the deteriorating epidemiological situation of HPAI observed in Western Europe. However, on April 21 and 22, 2022, respectively, two outbreaks of HPAI were confirmed in the western Wielkopolskie province, affecting large commercial farms keeping laying hens and slaughter turkeys. Despite the unfavorable HPAI situation, the economic impact of the disease on trade and exports is not significant.
