Canada reports outbreak of H5N5 bird flu on backyard farm

PARIS, Feb 18 (Reuters) - Canada has reported an outbreak of highly pathogenic H5N5 avian influenza on a non-commercial backyard layer poultry farm in the eastern part of the country, the World Organisation for Animal Health said on Tuesday.

The spread of avian influenza, commonly called bird flu, has ravaged flocks around the world, disrupting supply and fuelling higher food prices. Its spread to mammals, including dairy cows in the United States, has raised concerns among governments about a risk of human transmission.
