(Naju=Yonhap News) Reporter Jang Deok-jong = Quarantine authorities have taken initial measures at a duck farm in Naju, South Jeolla Province, following a suspected outbreak of highly pathogenic avian influenza (AI). According to South Jeolla Province, H5 type AI antigen was detected at a farm in Jong-ori, Bannam-myeon, Naju City. This farm raises approximately 8,000 ducks, and the owner reported a decline in egg production and an increase in mortality to the quarantine authorities. After the South Jeolla Provincial Animal Hygiene and Testing Institute collected samples and conducted a detailed examination, H5 type AI antigen was detected, and the Animal and Plant Quarantine Agency is currently determining whether it is highly pathogenic. South Jeolla Province has deployed an initial response team from the Livestock Hygiene and Quarantine Support Headquarters (2 people) to implement quarantine measures at the farm, including controlling access and disinfection. Considering that the farm is located in an existing quarantine area, the existing quarantine area is being maintained, and movement restrictions, disinfection, and surveillance are being implemented. Additionally, two field support officers have been dispatched to conduct a detailed investigation into the cause of the outbreak. South Jeolla Province plans to preemptively cull the affected farm to prevent further spread, and to thoroughly conduct post-management, including cleaning, disinfection, and preventing environmental pollution in the surrounding areas. Currently, highly pathogenic avian influenza has occurred in 28 cases nationwide, and in South Jeolla Province, there have been 5 cases in Naju and Yeongam. cbebop@yna.co.kr
