The Canadian Food Inspection Agency has confirmed the presence of highly pathogenic avian influenza in a small flock of poultry in Richmond, B.C.
The agency did not provide information on the number of birds infected by H5N1, or the type of poultry.
It says while the so-called bird flu is not a food safety concern, it is spreading across the globe and anyone with birds must use preventive measures like securing their property by a fence.
It says small flocks are at risk of contracting viruses like avian influenza, especially if they have access to ponds or bodies of water known to be used by wild birds.
H5N1 can also be spread on the clothing and shoes of visitors and employees moving from flock to flock, through contaminated feed, water, bedding and farm equipment as well as via airborne particles and dust blown by the wind.
B.C.'s Agriculture Ministry said this week that avian flu had been found in a commercial flock in the Fraser Valley, home to 80 per cent of the province's poultry farms.
Avian flu cases have been confirmed in several other provinces, but no infections have been detected in humans.
