Fifth Farm Quarantined in Canada Bird-Flu Outbreak
Preliminary Tests From the Turkey Farm Show the H5 Type of Virus
By NIRMALA MENON
Dec. 6, 2014 7:20 p.m. ET

OTTAWA—Canadian officials said a fifth poultry farm in a region in the western province of British Columbia that is battling an outbreak of avian influenza has been quarantined, and preliminary testing indicates the H5 strain of the virus.

The Canadian Food Inspection Agency will conduct further testing on samples from the site, a turkey farm, the agency’s chief veterinary officer Dr. Harpreet Kochhar said in a conference call Saturday.

The outbreak earlier this week in Fraser Valley, in the southwestern part of British Columbia, has prompted the U.S. and six other countries to impose bans of varying degrees on poultry imports from Canada, officials said.

The U.S. banned imports of all poultry products from British Columbia, while South Korea and South Africa barred shipments from all of Canada. Hong Kong, Japan, Mexico and Taiwan have also imposed restrictions.

Dr. Kochhar said the bans aren’t permanent, and that he is hopeful they will be lifted “once we have demonstrated that we have been able to combat this situation.”

He reiterated that the avian flu virus doesn’t pose risks to food safety when poultry and poultry products are properly handled and cooked. The virus rarely affects humans who don’t have consistent contact with infected birds.

Dr. Kochhar disputed a suggestion that the outbreak is out of control.

He said the region where it occurred is densely populated with poultry farms, so the latest case wasn’t unexpected and there may be more cases as avian influenza is highly contagious and can spread rapidly. The source of the outbreak is unclear, and possibilities include wild or migratory birds, he said.

The fact that it has only been found at five farms thus far is “very much indicative of the possibility of the virus being restricted to a particular area of the province,” Dr. Kochhar said.

The farms are under quarantine to control the spread of the disease. Some 80,000 birds in the first four farms are in the process of being euthanized.

The latest farm has capacity for 60,000 birds, officials said.

5 British Columbia Farms Quarantined for Bird Flu
VANCOUVER, British Columbia — Dec 6, 2014, 7:31 PM ET
By JEREMY HAIINSWORTH Associated Press

Associated Press
Seven countries have imposed trade restrictions on Canadian poultry as a fifth farm in British Columbia's Fraser Valley was put under quarantine for avian influenza, officials said Saturday.

The Canadian Food Inspection Agency said that more than 140,000 turkeys and chickens from the affected farms will be euthanized.

The agency said the fifth farm near Abbotsford was quarantined after higher than normal turkey deaths were reported by a farmer Friday.

B.C. chief veterinary officer Dr. Jane Pritchard says 60,000 turkeys are in the fifth farm.

Avian influenza was first detected a week ago on a broiler-breeder chicken farm in Chilliwack which housed 7,000 chickens. About 1,000 of the chickens died from avian influenza.

Officials say no people have fallen ill.

The B.C. outbreak has led at least seven countries ?the United States, Japan, South Korea, Taiwan, China, South Africa and Mexico ? to ban poultry products from B.C. or all of Canada.

Canada's chief veterinary officer, Dr. Harpreet Kochhar said birds from the first farms where avian influenza was detected have already been euthanized.

Kochhar said the source of the infection is not yet known, although he added that it's possible that wild or migratory birds could have infected the farms. He said the focus is on containing the infection's spread.

Pritchard said there had been movement of birds between some of the infected farms.

In 2004, health officials ordered 17 million chickens, turkeys and other domestic birds slaughtered to contain an outbreak of avian influenza at 42 poultry farms in B.C.'s Fraser Valley, costing the poultry industry hundreds of millions of dollars.

Avian influenza poses little risk to people who are consuming poultry meat if it is handled and cooked properly.

In rare cases, the virus can be transmitted to people who have had close contact with the birds, health officials said.

The Canadian Food Inspection Agency confirmed Saturday afternoon that avian influenza had spread to a fifth Fraser Valley farm, a turkey producer near Abbotsford, B.C.

B.C. Ministry of Agriculture Chief Veterinary Officer Dr. Jane Pritchard says the turkey farm contains two barns with a capacity of 30,000 birds each.

The CFIA says given the highly contagious nature of the disease it anticipated other farms could be identified.

Avian flu confirmed at four Fraser Valley farms after testing
CFIA Chief Veterinary Officer Dr. Harpreet Kochhar says quarantine measure are in effect at each identified farm and rejected a suggestion the spread was out of control.

"Given that there is a big population of or a very dense population of poultry industry down there, it was not unexpected that we would find other additional at-risk farms because avian influenza is highly contagious," he said.

"This can not be characterized at this moment as an out-of-control outbreak, however, we are expecting that given the virus virulence and contagiousness of the disease that we might find some other farms which could come out positive."

The CFIA says the potential addition of 60,000 more birds from the fifth farm now puts the cull of infected poultry, which is already underway, at about 80,000 birds.

Canada's chief veterinary officer has already said the federal government will compensate farms for each bird destroyed.

World markets impose bans, restrictions

World markets have reacted to the outbreak, leading seven countries—the United States, Japan, South Korea, Taiwan, China, South Africa and Mexico​—to impose trade restrictions on poultry and poultry products from all of Canada.

Hong Kong has imposed an outright ban on any poultry meat or products from the entire Fraser Valley Regional District.

It imported 7,000 tonnes of frozen poultry and about 170,000 poultry eggs from Canada between January and October of this year.

Hong Kong has had its own problems with avian flu, including an H5N1 outbreak in 2011 that led to the slaughter of more than 19,000 birds and a ban on the sale of live poultry for three weeks.

Fifth farm owner approached CFIA on Friday

The CFIA's Kochhar says the farmer at the fifth farm approached the CFIA on Friday and provided samples which were tested Friday evening and found to be positive for the H5 type early Saturday morning.

The federal government has confirmed the type of avian flu found at a turkey farm in Abbotsford and a chicken farm in Chilliwack as the highly pathogenic H5N2.


Poultry
The H5 avian influenza virus has been detected at a fifth farm, a turkey producer near Abbotsford.

​Further testing at two other nearby farms that received chickens from the Chilliwack site have confirmed H5 avian flu, but the strain from those farms and from the fifth farm has yet to be identified.
Complicating the containment, said Kochhar, is the sheer number of poultry farms in such a small area. He said there are 42 poultry farms in a three-kilometre radius in one production zone alone.

When asked how the disease continues to spread despite CFIA quarantines, Kochhar said the flu can be spread by other sources including wild or migratory birds.

​There have been three previous outbreaks in Canada involving the low-path strain of H5N2 — two in B.C. and one in Manitoba.

Officials have cautioned that the virus does not pose a risk to consumers if poultry meat is properly handled and cooked, though in rare cases it can be transmitted to people who work in close contact with the animals.

The B.C. Poultry Association has said it is confident biosecurity measures will be able to stop the spread of avian flu in the region.

No human has become ill from an H5 influenza outbreak, according to public health officials.

Avian influenza in Fraser Valley confirmed as H5N2 virus
OTTAWA, December 4, 2014

The Canadian Food Inspection Agency (CFIA)'s testing at the National Centre for Foreign Animal Diseases has confirmed the strain causing the avian influenza outbreak on two farms in the Fraser Valley as a highly-pathogenic H5N2 virus.

The Province of British Columbia has informed the CFIA that preliminary test results from the two additional farms that were quarantined yesterday are presumptive positive for H5 avian influenza. The CFIA will conduct further confirmatory testing.

Avian influenza viruses do not pose risks to food safety when poultry and poultry products are properly handled and cooked. Avian influenza rarely affects humans that do not have consistent contact with infected birds. Any illness would be mild. Public health authorities are ready to take precautionary measures as required.

H5N2 is a subtype that is known to affect wild and domestic birds. A highly pathogenic virus causes severe illness and death in birds, particularly poultry, whereas a low pathogenic virus causes less severe illness and lower rates of mortality.

A low-pathogenic H5N2 avian influenza virus caused outbreaks in Manitoba in 2010 and British Columbia in 2009.

All birds on the infected premises will be humanely euthanized in the coming days, under CFIA supervision. When animals affected by a disease are ordered destroyed by the CFIA under the Health of Animals Act, the farmer is also informed that they will receive compensation. The CFIA is dedicated to working directly with affected producers so that the compensation process runs as smoothly as possible.

As the CFIA's investigation progresses, any additional control measures will be assessed on a case-by-case basis.

Poultry farmers are reminded to practice a high level of biosecurity to reduce the risk of disease spread, and report any suspicious symptoms in their flocks to the CFIA.

Epidemiology
Epidemiological comments
Testing at the Canadian Food Inspection Agency (CFIA) National Centre for Foreign Animal Disease (NCFAD) on samples from outbreaks number BC-2014-NAI-001 and BC-2014-NAI-002 was performed: RT-PCR and partial sequencing of the H and N gene segments indicates a
poly-basic cleavage site in H5 consistent with Highly Pathogenic Avian Influenza Virus and the virus being a H5N2 Avian Influenza Virus with an IVPI of 2.96-2.98.
The CFIA has also confirmed H5 avian influenza virus in 3 additional farms (outbreak number BC-2014-NAI-003, BC-2014-NAI-004 and BC-2014-NAI-005) with clinical signs.
Farms from outbreak number BC-2014-NAI-001, BC-2014-NAI-002, BC-2014-NAI-003 and BC-2014-NAI-004 have been humanely depopulated.
At this point, this event is limited geographically to a portion of the Fraser Valley in the southern fringe of the province of British Columbia. Infected premises were quarantined by the Canadian Food Inspection Agency (CFIA) and a stamping out policy is being implemented, as
described in the Notifiable Avian Influenza (NAI) Hazard Specific Plan. The Canadian Notifiable Avian Influenza Surveillance System (CanNAISS) is an ongoing surveillance system built to demonstrate absence of NAI in poultry in Canada. CanNAISS results and epidemiological
investigation to date are supporting that there is no evidence of infection outside of the Fraser Valley in British Columbia.
On 8 December 2014, the Canadian Food Inspection Agency (CFIA) has established a primary control zone in the area where the disease has been identified. The primary control zone is bordered on the west by the Pacific Ocean, on the south by the United States border, on the
north by Highway 16, and on the east by the border between British Columbia and Alberta. Additional information on the zone and the restrictions in place are available at
http://www.inspection.gc.ca/an.imals/te ... 8073267337.
