  • China: Chicken carcass found at Lung Kwu Tan beach in Hong Kong tests positive for H5N6 virus - February 19, 2016

    A spokesman for the Agriculture, Fisheries and Conservation Department (AFCD) said today (February 19) that a chicken carcass found at Lung Kwu Tan, Tuen Mun, was confirmed to be H5N6 positive after laboratory testing.

    Four highly decomposed chicken carcasses were collected at a beach near Tin Hau Temple, Lung Kwu Tan, Tuen Mun, on February 14. Of them, one tested positive for H5N6 while the other three were negative.

    The spokesman said there were no poultry farms within 3 kilometres of where the dead chicken was found. AFCD staff will inspect the villages near Lung Kwu Tan and monitor if there is any backyard poultry.

    A ban on backyard poultry has been in force since 2006. Unauthorised keeping of five kinds of poultry - chickens, ducks, geese, pigeons or quails - is an offence with a maximum fine of $50,000. Repeat offenders are subject to a maximum fine of $100,000.

    The AFCD will conduct inspections of poultry farms and the wholesale market to ensure that proper precautions against avian influenza have been implemented. Samples will be taken from poultry farms for laboratory tests. The department will also continue its wild bird monitoring and surveillance.
