Farmers on alert as avian flu found on 4th southern Ontario farm

Ontario farmers are stepping up biosecurity measures as a fourth southern Ontario farm has been placed under quarantine after avian flu was detected in poultry flock.

The "highly pathogenic" H5N1 strain of avian flu is spreading around the world among wild birds, and has already been reported atcommercial farms in Atlantic Canada and throughout the United States.

• Avian flu found at southern Ontario poultry farm

The Canadian Food Inspection Agency has confirmed avian flu cases at three Ontario farms: in Woolwich Township, part of Waterloo Region;Zorra Townshipnear London; and in Guelph/Eramosanear Guelph. The most recently reported case involves a poultry flock in the Township of Chippewas of Nawash Unceded First Nation.

The CFIA has placed all thefarms under strict quarantine,establishing movement controls and recommending higher biosecurity at nearby farms.

Last week, the agency also confirmed avian flu in a wild red-tailed hawk in the Waterloo, Ont., area.

The provincial Ministry of Agriculture, Food and Rural Affairs says avian influenza is not a significant public health concern for healthy people who aren'tin regular contact with infected birds, and isnot a threat to food safety when there's proper handling and cooking.

A flock health issue

The detection of avian flu hasOntario farmers likeIngrid DeVisser concerned for their flocks andlivelihoods.

"We are being extremely vigilant and watchful," DeVisser, who owns a family turkey farm in Bruce County, told CBC News. "We normally use excellent bio-security and we have stepped it up a notch, if that's possible."

DeVissersaid the farm isalready doing much of itsbusiness remotely and isnowlimiting visitors toessential services.

She's alsolimiting the number of people working in the barn and has adopted stringent safety protocols, including sanitization, wearing personal protective equipment and changing work clothing regularly.

"As farmers, our main priority is to keep our birds safe and healthy,"DeVissersaid. "That's what we're working onand that's what we're being very careful about."

'Detective work' needed

Shayan Sharif, a professor and associate dean of research and graduate studies at the Ontario Veterinary College at the University of Guelph, said it's importantto limit the spread of avian flu as much as possible.

"What's required is significant amounts of detective work" by the CFIA, Sharif said.

"It is quite possible that migratory birds are coming from various other places into Ontario and spreading the virus, and those three farms could be connected."

Sharif said every effort should be made to restrictmovement of people and exchange of materials between infected farms as well.

It's not just farms taking precautions. This week, the Toronto Zoo announced "out of an abundance of caution" it would close its walk-through bird aviaries in pavilions to guests and behind-the-scenes toursof animal food preparation and bird housing will be temporarily suspended. It'salso enhancing safety measures for all staff.

'Enjoy your Easter turkey'

LisaBishop-Spencer, who'swith the Chicken Farmers of Canada, saidthe most important message is that general public does not need to be concerned about contracting avian flu.

"You would have to be in some pretty intense contact with infected birds and prolonged contact to, you know, to risk getting avian flu. And it's not in your food," she said.

"Health Canada is definitive that this is not a food safety or quality issue. It's a flock health issue. There's no risk to the health of the general population."

DeVisseragreed, saying, "I guess my message as a turkey farmer is, please continue to enjoy your Easter turkey."

DeVissersaidwhile it's unfortunate that avian flu outbreaks are occurring during the COVID-19 pandemic, her experience during COVID-19 hasleft her better equipped to manage the situation, and shehopes other farmers can draw on that experience as well.

"We're hoping we're going to be able to mitigate this outbreak and keep it as small as we possibly can," DeVisser said. "The message to everybody is: bio-security, practice your bio-security. Just be as careful as you can be."
