The avian influenza viruses recently detected in Gyeonggi Province and on Jeju Island have been confirmed as low pathogenic strains, the agriculture ministry said Tuesday.
Bird flu viruses were discovered in samples of wild bird droppings collected from a river in Suwon, 46 kilometers south of Seoul, and from the southern resort island of Jeju earlier this month.
The Ministry of Agriculture, Food and Rural Affairs said low pathogenic H5N2 was separated from the samples in an in-depth examination.
Low pathogenic AI strains cause only mild symptoms and may easily go undetected, while highly pathogenic subtypes spread rapidly across poultry farms and cause serious problems.
Quarantine authorities have stepped up disinfection and monitoring of local poultry farms as wild birds are flocking to the Korean Peninsula ahead of the winter season. (Yonhap)
