    • On 7 February 2017, a batch of ducks (3,787 heads) originating from one of the farms under intensified surveillance in Hualien County was intercepted in an abattoir located in Yilan County.
    • The duck farm is under intensified surveillance because it is within the 3 km radius of one dead young goose positive for H5N6 that was reported on 6 February 2016.
    • The ducks were transported to Yilan County on 6 February, one day ahead of the entry into force of the ban on the dispatch of waterfowls of Hualien County to other regions of the country.
    • The carcasses of the ducks intercepted in the abattoir were sampled and tested using RT-PCR and gene sequence analysis by the National Laboratory (Animal Health Research Institute, AHRI).
    • H5N6 and H5N2 subtypes HPAI were detected and confirmed by the AHRI on 11 February 2017.
    • All of the 3,787 carcasses were condemned and destroyed, and thorough cleaning and disinfection have been conducted in the abattoir.
    • The farm of origin has been sampled for testing.
    • The intensified surveillance zone has been enlarged to 5 km radius surrounding the index farm.
    • Sampling is underway and will be completed as soon as possible in order to detect any spreading of the viruses.
    • These control measures will be imposed on the area for at least 3 months and will be lifted only after the confirmation of the elimination of the viruses.
