  • Canada - Avian influenza confirmed on southern Ontario duck farm - LP H5N2

    July 08, 2016, EDT.


    OTTAWA — A duck farm in St. Catharines, Ont., has been placed under quarantine because of H5 avian influenza.

    The Canadian Food Inspection Agency says preliminary testing has confirmed the presence of the virus and further testing is underway to determine its precise subtype and strain.

    The CFIA says those results are expected within days.

    In addition to the quarantine, the CFIA says it will draw up a surrounding surveillance zone for further testing and control measures.

    The CFIA says all birds on the infected farm will be euthanized and it will oversee the cleaning and disinfection of barns, vehicles, equipment and tools to eliminate any infectious material that may remain.

    Avian influenza rarely affects humans and does not pose a risk to food safety when poultry and poultry products are properly handled and cooked.

    Avian influenza confirmed on farm in Southern Ontario




    Ottawa, July 7, 2016
    Preliminary testing by the Canadian Food Inspection Agency (CFIA) has confirmed the presence of H5 avian influenza on a duck farm near St. Catharines, Ontario as a low pathogenic subtype. Pathogenicity refers to the severity of the illness caused in birds. Further testing by the CFIA is underway to confirm the precise subtype and strain of the virus. Results are expected within days.
    The CFIA has placed the farm under quarantine to control disease spread and will determine a surrounding surveillance zone for further testing and movement control measures. The industry sector has been notified to adopt enhanced biosecurity practices.
    Avian influenza does not pose a risk to food safety when poultry and poultry products are properly handled and cooked and rarely affects humans. Public health authorities stand ready to take precautionary measures as warranted.
    All birds on the infected premises will be humanely euthanized and disposed of, in accordance with provincial environmental regulations and internationally accepted disease control guidelines, and the Province of Ontario will provide technical support on required carcass disposal. Once all birds have been removed, the CFIA will oversee the cleaning and disinfection of the barns, vehicles, equipment and tools to eliminate any infectious material that may remain.
    The CFIA, the Province of Ontario, the owner of the infected birds, and the poultry industry are working closely together to manage the situation. Both levels of government will work with the poultry industry to address issues as they emerge. The Canadian poultry sector currently practices a high level of biosecurity that reduces the risk of disease spread.

      TORONTO — About 14,000 ducks quarantined at a commercial farm in St. Catharines, Ont., will be euthanized because of the H5N2 avian influenza.

      Harpreet Kochhar, chief veterinary officer with the CFIA, says the virus is a low pathogenic subtype, meaning it causes a milder illness in birds.

      The CFIA says all birds on the infected farm will be euthanized, and it will oversee the cleaning and disinfection of barns, vehicles, equipment and tools to eliminate any infectious material that may remain to guard against the virus spreading.

        Avian influenza investigation in Ontario - 2016

        The Canadian Food Inspection Agency (CFIA) has confirmed the presence of low pathogenic H5N2 on a duck farm near St. Catharines, Ontario.

        The Canadian Food Inspection Agency Establishes Avian Influenza Control Zone


        July 10, 2016

        The Canadian Food Inspection Agency (CFIA) has established an Avian Influenza Control Zone in Ontario to control the movement of animals, products and equipment in the area to minimize disease spread.

        The boundary of the Avian Influenza Control Zone covers a 3km radius from the single premises confirmed to be infected with avian influenza, located near St. Catharines, Ontario.

        All premises located within this zone will be placed under quarantine; however, only the initial infected premises has confirmed positive for avian influenza. The Agency is monitoring all premises within the zone for any signs of disease.

        The Avian Influenza Control Zone is part of an internationally accepted practice to allow trade to continue from non-infected areas of a country. We continue to work very closely with industry and our international partners as this situation develops.

        Avian influenza does not pose a risk to food safety when poultry and poultry products are properly handled and cooked. Avian influenza rarely affects humans that do not have consistent contact with infected birds.

        Poultry farmers are reminded to practice a high level of biosecurity to reduce the risk of disease spread, and report any suspicious symptoms in their flocks to the CFIA.

        For more information on avian influenza and measures poultry farmers can take to protect their flocks, please visit theNotifiable Avian Influenza page on the CFIA website.

          Epidemiological comments On July 4, 2016, 30 birds from a domestic duck farm were sampled as part of an export surveillance testing for avian influenza and were submitted to the National Centre for Foreign Animal Disease (NCFAD). The ducks were clinically healthy. Total RNA was extracted from 30 swab samples; 15 tested positive for influenza A matrix, and 13 for H5 using real time RT-PCR assays. The neuraminidase was typed as N2 using short N-typing conventional RT-PCR assay. The sequence of hemagglutinin cleavage site motif is consistent with LPAI viruses of H5 subtype. Top matches of the sequenced 426 bp RT-PCR product are North American wild bird origin LPAI viruses of H5 subtype.

            Wild fowl caused Lincoln duck farm outbreak
            By Maryanne Firth, St. Catharines Standard
            Monday, October 24, 2016 5:09:17 EDT PM

            It was through contact with wild fowl that an outbreak of avian influenza occurred on a Lincoln duck farm this summer.

            But wild birds, including migratory waterfowl, have played a much larger role in the spread of the virus into Europe and North America.

            That was the conclusion reached by a group of scientists from across the globe, who recently published their findings focused on avian influenza and the impact of migratory birds...
