    Animal quarantine authorities in Taiwan have slaughtered at least 150,000 poultry after an outbreak of the bird flu in many counties and cities on the self-ruled island.

    On Saturday, 11 farms in Hualien, Tainan, Chiayi and Yunlin were confirmed as having been infected with the H5N6 virus, which is highly contagious and transmittable to humans, according to the Bureau of Animal and Plant Health Inspection and Quarantine under the Council of Agriculture.

        Taipei (Taiwan News)?Hsinchu County in northern Taiwan reported its first case of H5N6 this year, as 400 abandoned dead chickens tested positive for the pathogenic avian flu virus.
        ...
        Samples taken from the dead chickens sent to the Animal Health Research Institute lab in New Taipei City for further analysis returned positive for the H5N6 virus.
        ...
        The latest case reported in Hsinchu increases the number of counties affected by the bird flu from five to six, and brings the total cases of the current H5N6 outbreak to 17, according to Council of Agriculture?s (COA) latest statistics.

        Earlier Monday, the COA reported three new cases confirmed last Saturday, including a chicken farm in Yunlin County, a goose farm in Chiayi County and ducks at a slaughterhouse in Yilan County. The case in Chiayi marks the first case of bird flu in geese discovered in Taiwan this year.

        As of Sunday, all the cases reported were from eight poultry farms in Hsinchu County, Yunlin County, Chiayi County, Tainan City, Yilan County and Hualien County.

        An outbreak of the contagious H5N6 that is transmittable to humans has led to the culling of 188,696 birds in 28 poultry farms and five slaughterhouses, stated the COA.

          Epidemiological comments 1.Abnormal mortality was observed in 8 poultry farms in Yunlin County, Tainan City, Yilan County, and Chiayi County. Samples were sent to the National Laboratory, Animal Health Research Institute (AHRI) for analysis. Highly pathogenic avian influenza H5N6 subtype was confirmed by the AHRI. The farms have been placed under movement restriction. All animals on the infected farms have been culled. Thorough cleaning and disinfection have been conducted after stamping out operation. 2.In order to prevent the H5N6 HPAI virus from spreading, intensified surveillance measures have been conducted by veterinary authority. All the duck farms within 5-kilometer radius of the infected farm shall be subjected to movement restriction and avian influenza test. The restriction could be released if the result is negative. In addition, all the poultry farms within 1-kilometer radius of the infected farm shall be subjected to movement restriction and avian influenza test for once a month for 3 months. The restriction could be released if the result of first test is negative. Despite of the abovementioned measures, all poultry farms within a 3-kilometer radius of the infected farms are under monitoring for three months.
