Bird feeders are OK but keep wild birds from backyard chickens as avian flu spreads in Ontario: experts

With 11 confirmed cases of avian influenza in Ontario poultry flocks, according to the CFIA, experts warn anyone with backyard chickens to be on the alert for flu signs and also recommend precautions for bird watchers.

CFIA has confirmed bird flu at 11 Ontario sites, including in 3 backyard flocks

As avian influenza spreads across Ontario, officials are urging people with backyard chickens to pay attention to potential signs of infection in their flocks.

They're also warning people not to feed wild birds by handand to ensure bird feeders are kept cleanto curbpotential spread of the flu.

Shayan Sharif, a professor at the Ontario Veterinary College at the University of Guelph, saidbird flu is a growing problem in Ontario and across Canada.

"There seems to be more and more spread of this virus," Sharif,who researches chicken immunity, said in an interview.

"And I wouldn't be surprised if I saw more spread here in Ontario and perhaps in our neighbouring provinces, including in Quebec and Manitoba."

The Canadian Food Inspection Agency (CFIA) says there have been 11 instances of avian flu being confirmed in Ontario poultry flocksbetween March 27 and April 10. That includes three backyard flocks in Prince Edward County, the Township of Selwyn and the Township of Chippewas of Nawash Unceded First Nation.

As well, a wild bird a red-tailed hawk wasfound to have the flu in the Waterloo area in mid-March.

In a technical briefing Monday afternoon, officials noted more than260,000 birds have died of avian flu or have been "depopulated" as part of the national response to the virus. In Ontario, more than 84,000 birds died of flu or have been euthanized.

Mary Jane Ireland,Canada's chief veterinary officer, said it's been an "unprecedented year" for avian flu around the globe, with significant spread in Europe, Asia, Africa and North America. She said it's the largest number of cases in multiple provinces in recent memory and the first time Canada has seen H5N1, a highly pathogenic avian influenza strain.

When asked why avian flu has been so widespread this year, she said it's because there's a high number of wild, migratory birds with the virus.

"The environmental pressure in migratory birds is very high right now and I think that's the reason."

Keep backyard chickens apart from wild birds

Avian flu isn't only a threat to large poultry farms, but it can impact backyard flocks, CFIA says. Bird owners are legally responsible to notify authorities if their animals become sick.

Ireland noted infected birds can shed the virus through saliva, nasal secretions and feces, and it can be spread through bird-to-bird contact or if the birds touch surfaces contaminated with the virus, including food dishes, a person's shoes or the tools used to clean out coops.

Ireland said stepspeople with backyard chickens can take to prevent wild birds from coming in contact withchickens include keeping food and water away from wild birds, and cleaning up spills so as to not attract unwanted birds.

Cleaning is also critical at this time, CFIA says on its website

"No equipment should be shared with or borrowed from other bird owners. Always clean your hands, clothing and footwear before and after handling birds."

As well, visitors to where chickens are kept should be limited, as humans can spread bird flu.

Any new chickens should be kept separate from others for at least 30 days before integrating them into the flock, CFIA says.

Owners of backyard chickens should also keep their eyes out for the following symptoms that may indicate the birds are sick:

  • High mortality and sudden death.
  • Decreased food consumption.
  • Huddling, depression, closed eyes.
  • Respiratory signs (coughing and sneezing).
  • Decreased egg production.
  • Watery greenish diarrhea.
  • Excessive thirst.
  • Swollen wattles and combs.

Farmers in Ontario are keeping a close eye on a deadly strain of bird flu thats forced some poultry farms into quarantine. At least one expert says consumers shouldnt be worried because its extremely unlikely the virus will make its way into the supply chain.

Take precautions feeding wild birds

Elizabeth Walsh, a Nova Scotia Lands and Forestry wildlife biologist, told CBC News thatpeople with backyard bird feeders might want to consider removingthem for the time being.

"Removing feeders will help stop the virus from spreading. I do realize people enjoy their feeders. However, as a bird lover, we also want to be making sure that our wild populations are safe," she said.

Christopher Sharp, a population management biologist with the Canadian Wildlife Service in Ontario, saidhe's not asking people to take down bird feeders just yet.

But he does recommend against feeding ducks and other waterfowl in parks right now.

"Feeding encourages wild birds to congregate around a food source and can increase the probability of transmission among wild birds," Sharpsaid in an interview.

"We do still consider the use of bird feeders as safe, but they should be removed from areas that are open to poultry or other domestic animals."

Sharp said backyard bird enthusiasts should also clean theirfeeders more frequently.He recommendsusing aweak solution of regular bleach, then ensuring the feeders are rinsed well and dry before putting themback out.

When it comes to feeding some birds, like chickadees, by hand, Sharp recommends not doing that for now because "all wild birds can contract the virus."

Sharif agreed that people with backyard feeders need to take extra precautions to avoid spreading the flu.

"As much as I want to attract the beautiful birds in Ontario to my backyard, this is probably not the best time for that."
