Avian flu leads to B.C. turkey shortage ahead of Christmas

A 20 per cent shortfall among B.C. turkey producers is expected to last through Christmas, says the B.C. Poultry Association.

Christmas dinner in British Columbia could look a little different this year as nearly two dozen farms across the province slaughter hundreds of thousands of birds in an attempt to contain the avian influenza virus. 

From the Interior, to the Fraser Valley and Vancouver Island, the Canadian Food Inspection Agency (CFIA) has identified high-pathogenic strains (HPAI) of H5N1 — the most deadly variety of avian influenza or “bird flu”— in 42 B.C. flocks. As of Wednesday afternoon, 23 outbreaks were ongoing and 275,800 birds had been slaughtered in an effort to contain the pathogen. 

The culled birds include broiler chickens, ducks and laying hens, among other specialty birds. But the most heavily affected poultry has been turkey, says Amanda Brittain, chief information officer for the BC Poultry Association, the group that helps coordinate the province’s four poultry and egg marketing boards during emergencies. 

“The BC Turkey Marketing Board tells me that they’re looking to be 20 per cent short of how much they grow,” said Brittain. “Turkeys grow for 13 to 15 weeks, so there is no time to grow more before Christmas.” 

H5N1 has been identified at over 220 locations across Canada and led to the culling of 3.7 million birds since the start of the latest epidemic. 

The seven commercial Fraser Valley poultry farms hit with the virus since Nov. 16 have come under “intense disease pressure,” said B.C. Minister of Agriculture Lana Popham.

Island supplies limited

On the Vancouver Island, avian flu outbreaks have been contained to small backyard flocks, but all producers remain on high alert.

One of the Island’s largest ­diversified poultry producers, Firbank Farms, which produces about 100,000 birds at a time on the Saanich Peninsula, has not been affected by the disease and ­continues to adhere to strict protocols.

“We’re all safe, touch wood,” co-owner Diane Williamson said Friday.

There are no large-scale turkey ­producers on Vancouver Island, with most farmers raising a few dozen to up to 500.

One of the capital region’s largest turkey producers, Ireland Farms, got out of the business two years ago. The Saanich Peninsula farm had produced about 1,500 turkeys a year.

Bryce Rashleigh of Saanichton Farms has 50 turkeys ready for ­Christmas dinners this year, but those have already been sold.

Rashleigh said he has ordered 50 turkey chicks for delivery on Dec. 22, but with the tenuous avian flu ­situation ­everything is up in the air because Lower Mainland farms that provide stock are managing day to day.

“We have one of the biggest ­producers on the Island out of the ­picture now, farmers retiring and ­getting older, the cost of feed is through the roof and now avian flu … it’s ­knocking everyone in the teeth,” said Rashleigh.

Rashleigh said the permit paperwork now required to move live birds is cumbersome, but essential to keep flocks safe.

Retailers are bracing for shortages.

A spokeswoman at Glenwood Meats in Langford said turkeys are expected to arrive on Dec. 21, but that could change.

She said Glenwood is not taking orders from customers. “We’re doing first-come, first serve … with avian flu, we have no idea what’s going to happen,” said the spokeswoman. “It’s the same with turkey parts. We never know what we’re going to get or when.”

From the wild to the farm

The outbreaks in Chilliwack and Abbotsford come out of step with the seasonal migration of wild birds, which have been found to carry and pass on the virus to domestic flocks. 

"The virus this year is different than we've ever seen in the past and it is behaving differently in both wild birds and domestic birds," said Brittain. 

Scientists have isolated variants of the influenza virus in more than 100 wild bird species worldwide, from waterfowl like geese, swans, ducks and gulls to shoreline species like sandpipers, plovers and storks. Not all strains are deadly. In the same way that many humans pull through an annual bout of the flu, many strains of the avian varieties rarely cause more than the sniffles, lethargy or fever in birds.

High-pathogenic strains are different. When HPAIs enter a poultry farm, they often find the epidemiological equivalent of a refugee camp for birds, says Ronald Ydenberg, a professor of behavioural ecology and director of Simon Fraser University’s Centre for Wildlife Ecology. 

“There are thousands of birds there. They're all immunologically naive. They haven't had time to evolve any resistance. And there's a fresh batch every six weeks,” he told Glacier Media last spring.

The viruses that cause avian flu can be shed through a bird’s saliva, feces and nasal secretions. If an infected animal sheds into a pond, near a bird feeder or in a cramped barn, it can easily pass on to another individual — whether wild or domestic. 

This is where turkeys may be most vulnerable, says Brittain. Some are raised in open barns, where only partial walls and tarps protect the flocks from foul weather. 

“In an open barn, it’s harder to prevent the migratory birds from getting in,” she said. 

Avian flu in pets and humans

CFIA says there have been no cases of wild birds passing the virus to humans in Canada, but transmission from pet birds to humans is still a risk.

“Current science suggests that the risk of a human contracting avian influenza from a mammalian pet is very low,” notes the federal agency. 

Owners are still encouraged to take appropriate precautions to protect their pets and themselves.

There’s always a potential for low-pathogenic avian flu viruses to evolve into highly pathogenic viruses. Such a novel virus could emerge with pandemic potential among the human population.

“H5N1 infection in humans can cause severe disease and has a high mortality rate,” states the WHO. “If the H5N1 virus were to change and become easily transmissible from person to person while retaining its capacity to cause severe disease, the consequences for public health could be very serious.”

Since highly pathogenic Asian bird flu strains emerged worldwide in the past two decades, many worried H5N1 would jump to people like the incredibly deadly Spanish Flu 100 years earlier, said Ydenberg.

But “it just didn’t happen,” he added.

​Ydenberg says there is little evidence that this wave will be any different.

“I would say vigilance is required here. But certainly, if I were an average person, I would not worry about this very much.”

That level of certainty is unlikely to be matched at the grocer aisle this Christmas.

Brittain said that people should have no concern eating poultry or eggs. Finding a big bird and a good price is another question. 

Since January, the wholesale prices of live turkeys in B.C. have climbed between 15 and 18 per cent depending on their size, according to Statistics Canada.

“We’re fine on chicken and eggs. But it is a concern with turkeys right now,” said Brittain.

“What I’m hearing is that avian influenza is making it very challenging for turkey farms and producers to meet demand in B.C. before Christmas. They have been hard hit.”
