A suspected outbreak of highly pathogenic avian influenza (AI) has been reported at a bell duck farm in Wonnam-myeon, Eumseong-gun, Chungcheongbuk-do, South Korea. The outbreak was identified during a Japanese inspection of egg-producing poultry farms, with the H5 type AI antigen detected. The local authorities have ordered the culling of 9,000 ducks on the affected farm, while poultry within a 3km radius will be culled preventively, excluding 274,000 poultry from five farms. This decision adheres to guidelines issued by the Ministry of Agriculture, Food and Rural Affairs in South Korea. The incident marks the continuation of AI outbreaks in the region, with seven farms in Chungbuk province already experiencing similar issues, leading to concerns and protests from livestock farmers about the economic impact of the preventive measures.
