A poultry farm situated outside the so-called bird flu “hot zone” in British Columbia has been placed under quarantine after birds there showed possible signs of avian influenza.

If the presence of the virus is confirmed, it would be the first case outside the 5km quarantine zone around the British Columbia farm where the outbreak was first detected last month, reported Dow Jones News.

Last week, Canadian officials announced that more than 200,000 chickens would be culled in a bid to stop the spread of the disease.
