    -- Epidemiological comments
    The cleaning and disinfection of the first infected premises (2009-BC-001) is now completed and has been approved by the CFIA (Canadian Food Inspection Agency) on 20 February 2009.
    All susceptible birds at the second infected premises (2009-BC-002) have been humanely euthanized on site on 12 February 2009.
    Destruction of carcasses by composting is underway, under the direct supervision of the CFIA.
    Cleaning and disinfection expected to be completed by the end of this week.
    No new outbreak was reported during the last period.
    To date, a total of 43 premises are maintained under quarantine by the CFIA within 3km of or with epidemiological link with the two infected premises, with active surveillance in place.
    The NCFAD (National Center for Foreign Animal Diseases) has completed the procedure for the determination of the Intravenous Pathogenicity Index (IVPI) of the AIV isolate from the first infected premises.
    The IVPI is 0 and, consequently, it is confirmed that the virus is a Low Pathogenic Notifiable Avian Influenza Virus H5N2.

    Note by the OIE Animal Health Information Department: H5 and H7 avian influenza in its low pathogenic form in poultry is a notifiable disease as per Chapter 10.4. on avian influenza of the Terrestrial Animal Health Code (2008).
