  • Vietnam: H5N6 outbreak in poultry in Ba Ria-Vung Tau Province

    10,500 chicken killed in southern Vietnam after bird flu outbreak
    By Nguyen Khoa August 6, 2019 | 06:41 pm GMT+7

    Ba Ria-Vung Tau Province has culled 10,500 chicken infected with the H5N6 virus to try and prevent further outbreaks.

    Nguyen Luong Trai, head of the southern province’s Animal Health Department, said Tuesday that infected chicken were incinerated and buried.

    Veterinary staff have also sprayed disinfectant and lime powder on affected livestock farms to contain the spread of the deadly virus strain, he said.

    The H5N6 strain, which has been spreading in neighboring China, was detected at a farm owned by Dao Thi Khanh in Xuyen Moc District last week after a flock of 9,000 chicken raised for around four months died suddenly. Later, around 1,500 other chicken in a poultry farm in the same locality tested positive for the H5N6 virus.

    It could be that the infected birds had not been fully vaccinated, the official said.

    Before the outbreak was detected, Khanh’s family had sold a few thousand chicken for meat; however, there have been no human infections reported in epidemic areas so far, Trai said...
