The H5 outbreak in Canada began over the weekend, and H5 was confirmed on Monday or Tuesday. Canada has never reported HPAI H5, and the delaying in the announcement of the N serotypes suggests it is N8 and matches the outbreaks in Asia and Europe.

Avian flu in Fraser Valley unlikely to spread: B.C. Poultry Association
Thousands of birds will be euthanized after virus was found on farms in Abbotsford and Chilliwack
By Jesara Sinclair, CBC News Posted: Dec 03, 2014 12:08 PM PT Last Updated: Dec 03, 2014 12:08 PM PT

The president of the B.C. Poultry Association has confidence security measures will prevent the spread of avian flu after it was discovered on two farms in the Fraser Valley.

The Canadian Food Inspection Agency confirmed the virus at a turkey farm in Abbotsford and a broiler chicken breeding facility in Chilliwack on Tuesday. Thousands of birds will be euthanized.

"When something like this happens, those farms are quarantined so nothing can come on or off of those places," Ray Nickel with the B.C. Poultry Association told The Early Edition's Rick Cluff.

"The farms that are in the surrounding area go into what we call a lockdown."

In 2004, millions of birds were killed after an outbreak of the virus.

Nickel said since that outbreak, new security measures have been put in place, and those new rules have already been proven to work.

"We managed through another outbreak in 2009 which hardly hit the map because of the way it was done," he said.

Turkeys from the farm in Abbotsford were destined to be sold for Christmas dinner.

Nickel said consumers shouldn't be worried about the quality of their meat.

"This is about bird health, this isn't a human issue as far as buying your product," he said.

The virus does not pose a risk to food products that are properly cooked.

@paulvieira: Canada food watchdog says in phone briefing 2 more poultry farms closed due to avian flu, adds it is "possible" other farms could be hit

@CitytvNews: CFIA says 2 more farms in the Fraser Valley have been placed under quarantine in the Avian flu outbreak.

@HelenBranswell: #CFIA says 2 more farms under quarantine in British Columbia after discovery of an H5 avian #flu virus. No results yet on pathogenticity.

@HelenBranswell: Canada's chief veterinary officer Harpreet Kochhar says the pathogenicity of the H5 avian #flu virus will be available "in coming days."

@HelenBranswell: Sounds like #CFIA doesn't yet know the N (neuraminidase) of the H5 avian #flu virus responsible for a poultry outbreak in BC's Fraser Valley

@HelenBranswell: #CFIA says it expects to know the N or neuraminidase of the H5 avian #flu virus in BC by late tomorrow afternoon.
