[TD]Abnormal mortalities were observed in 3 poultry farms in Taoyuan City, Hsinchu County and Chiayi County. Samples were sent to the National Laboratory, the Animal Health Research Institute (AHRI) for diagnosis. H5N2 subtype low pathogenic avian influenza (LPAI) was confirmed by AHRI. These farms have been put under movement restrictions. The pathogenicity of the virus has been subsequently confirmed by national laboratory as low pathogenic (less than 75% mortality of the tested chickens) on 20 July 2015. All animals on the infected farms have been culled on 31 January and 2nd February 2015. Thorough cleaning and disinfection have been conducted after stamping out operation. Surrounding poultry farms within 3 km radius of infected farms are under intensified surveillance for 3 months.[/TD]
