Taiwan: H5N6/H5N2 Confirmed At Local Duck Slaughterhouse


Five days ago, in Taiwan BAPHIQ: HPAI H5N6 Found In Dead Goose we saw the first detection of HPAI H5N6 in Taiwan - in a dead gosling found near some poultry farms. Authorities immediately set about testing all poultry farms within a 3KM radius.
While there were (faint) hopes this was an isolated finding, today Taiwan's  BAPHIQ (Bureau of Animal Plant Health Inspection & Quarantine) has announced the detection of both the HPAI H5N6 and HPAI H5N2 virus among frozen chickens shipped and processed from that area.
Nearly 3,800 frozen carcasses are to be destroyed.  It seems likely the H5N2 detected at this slaughterhouse is one of the two existing H5N2 viruses that have plagued Taiwan in recent years - but with the arrival of H5N6 - a new reassortant is always possible.

Based on H5N6's rapid spread in Korea and Japan, and Taiwan's difficulties in controlling HPAI H5N8 when it arrived on the island in 2015, infecting more than 1000 farms (see Taiwan Culled 5 Million Birds In 2015), today's announcement will doubtless set a lot of wheels in motion.

Meanwhile, the poultry farms within 5 km radius, subject to first detect the presence of virus-free, listed before slaughter. Another county will also conduct a comprehensive visit its jurisdiction all poultry farms.

Prevention and Quarantine Bureau emphasized that, according to the outbreak of H5N6 subtype highly pathogenic avian influenza experience Korea and Japan, the strong force of the spread of the virus through the waiting (wild) birds after the invasion, easy by poultry, personnel, vehicles, cages, equipment and wild birds other means of communication in the marketing environment.
Therefore, all domestic poultry industry should be alert to implement hold a cautious attitude inside the software and hardware biological Anquancuoshi, must not be taken lightly. Bureau shows that the poultry industry's first and foremost task is to strengthen the anti-bird birdhouse facilities, blocking the poultry with the incoming (wild) birds routes of exposure, and make access control, usually should be strictly prohibited outside the vehicles and personnel comes into play, if not be You must order comes into play, should also requires personnel to replace clothing and footwear, and rigorous disinfection of vehicles after Chedi, before entering. In addition, if found inside the case of poultry abnormal mortality or food intake, water intake, egg production rate decreased abnormal, should immediately notify the local animal epidemic prevention organs to assist in clarifying the reasons, but also to avoid the possible spread of the epidemic and marketing environment, the protection of the whole industrial safety.

NOTE:  As mentioned yesterday, my desktop computer is headed for 2-3 weeks of rehab (motherboard replacement).  Rather than rely on my badly under powered (and aged) netbook, I've bought a new laptop, and should have it up to speed today.  

My apologies for the light blogging over the past 24 hours.
