The article reports a severe outbreak of the highly pathogenic avian influenza virus, specifically the H5N1 strain, in two livestock farms in Hungary, leading to significant mortality among fattening turkeys and liver geese. The outbreak was identified following symptoms such as reduced feed and water consumption and increased mortality rates, with confirmatory testing by Nébih. As a result, the affected stocks are being culled, and the incident has led to the establishment of protection and surveillance zones. The authorities are urging pet owners to exercise caution against the spread of the virus across the country.
