Cleaning and disinfection work on an Abbotsford, B. C. turkey farm has been completed to the Canadian Food Inspection Agency’s approval after the farm’s stock was culled for avian flu.
About 60,000 birds were gassed and composted in the farm’s barns after some birds in the flock were confirmed Jan. 24 to have what turned out to be a low-pathogenicity H5N2 strain of avian influenza.
A second poultry farm nearby in B. C.’s poultry-concentrated Fraser Valley – where what appears to be a similar “low-path” H5 strain of bird flu was confirmed in the flock on Feb. 11 – has completed in-barn composting of its birds, to “inactivate” whatever virus they’re carrying.
Preparation for cleaning and disinfection has begun at that second site, CFIA said Feb. 27.
The second site was detected through routine surveillance of properties within a threekm radius of the first infected site.
As per international guidelines, Canada can again claim its status as free of notifiable avian flu, three months after all cleaning and disinfection activities on infected premises have been completed and approved by the CFIA – provided that surveillance has been carried out during that three-month period, the agency said.
Surveillance continues on the commercial poultry premises within three km of the first and second infected premises and any in-contact premises still under movement restriction outside of the three-km radius, CFIA said Feb. 27.
As of Feb. 26, CFIA said it has 43 premises quarantined in relation to these two cases.
