'Be extremely vigilant': farmers, feds worried about growing outbreaks of bird flu – Cornwall Seaway News
Growing cases of bird flu across Canada have left scores of chickens and turkeys dead, poultry farmers devastated, and Canada’s top veterinarian seriously concerned about the weeks ahead.
In less than a week, the H5N1 strain of avian influenza has ripped through three commercial poultry farms in southern Ontario, according to the Canadian Food Inspection Agency.
Those cases were confirmed after a red-tailed hawk in the Waterloo, Ont., region was found with bird flu 10 days ago.
The CFIA has placed those three Ontario farms under a strict quarantine and set up a 10-kilometre control zone to limit movement of animals. It’s also helped nearby farms put enhanced biosecurity measures in place to control the spread of the virus.
Dr. Mary-Jane Ireland, chief veterinary officer for the CFIA, said she’s worried about the days ahead given that it’s migration season for many wild birds that can spread the disease.
“It’s quite a devastating disease,” Ireland said in an interview.
“We are concerned, this is a high-risk period, and birds are migrating. We have detected it in Canada and more recently in Ontario … and that is why we’re asking people to take precautions.”
The bird flu outbreaks have led to 24 countries temporarily banning imports of birds or poultry products from parts of Canada and in some cases from the whole country, the CFIA said, although a farm stakeholder group has noted that Canada’s poultry production is largely for domestic purposes.
The risk to the general public is low. Bird flu is not a significant public health concern for humans, Ireland said, and food safety is not an issue, either.
The impact on farm operations, however, can be severe.
Avian flu began ripping through commercial farms in Europe last year and then hit the United States. It was confirmed in Canada on Dec. 22, 2021, with the CFIA saying it was detected on an exhibition farm on the Avalon Peninsula in Newfoundland and Labrador.
The virus was then found on Jan. 11 in a small flock on the same peninsula. The agency found it again in two commercial farms in Nova Scotia in February and a backyard duck and chicken flock in March.
Bird flu was first detected on a farm near Guelph, Ont., last Sunday. It was then found on a farm near London, Ont., on Monday and on another farm, in Woolwich, Ont., on Wednesday.
The H5N1 virus is highly contagious, Ireland explained.
“Infected birds can shed the virus in their saliva, their natal secretions and their feces,” she said. “And it can spread through contact with surfaces.”
Those surfaces can include shoes, litter, bedding feed and water, she said.
Anyone who has birds should keep them away from wild birds; frequently clean poultry coops, water, feeders and clothing; and control what goes in and out of a coop or barn, Ireland said.
Wild migratory aquatic birds are the major reservoir for the bird flu virus, she said.
“These birds, we think, have brought the disease into the area,” Ireland said. “And wild birds are migrating right now.”
The virus can also be brought into farms from contaminated manure and contaminated litter, she said.
Anyone who observes wild birds showing neurological symptoms, or farms that see sudden bird deaths, should contact the CFIA or a local vet, Ireland said.
The Feather Board Command Centre, a group of poultry farmers and members of the feed, process and service industries, helps respond to such emergencies, said its chair, Ingrid DeVisser.
“There’s a lot of stress on farmers, not just on the infected premises, but in the control zones right now,” DeVisser said.
With much of southern Ontario part of a natural flight zone for migrating aquatic birds, she said more outbreaks are expected.
“Farmers everywhere should be very aware of what is going on and be extremely vigilant on their farms with their biosecurity measures, whether they’re commercial farms or whether they’re backyard farms.
The board is helping affected farmers with cleaning measures and helping them navigate the paperwork involved with the CFIA and insurance companies after bird flu is found in their flocks.
She said all farmers, not just ones in the control zone, should be using dedicated clothing and boots when going into the areas where the birds are kept, using hair nets, masks, hand sanitizers and lots of cleaning.
Lisa Bishop-Spencer, a spokeswoman for the Feather Board Command Centre, said Canada doesn’t export much poultry so the temporary import bans as a result of the outbreaks aren’t having a significant impact.
“The Canadian poultry and eggs sector is a supply-managed sector, which means it provides for the domestic market primarily,” she said.
Ontario has recommended small flock owners and other zoological institutions avoid attending shows, swaps and sales at this time.
The Feather Board’s DeVisser, who is also a turkey farmer in Bruce County, Ont., said she’s constantly worried about the virus.
“We are just doing our utmost to be as vigilant as we can on our farm,” she said. “Watching our birds, keeping them healthy and doing whatever we can.”

Grande Prairie RCMP issued a warning Friday after it was revealed fentanyl linked to a deadly overdose was mixed with a chemical that doesn’t respond to naloxone treatment.
The drugs were initially seized on Feb. 28 after a fatal overdose, and this week, Health Canada reported back to Mounties that the fentanyl had been mixed with Bromazolam, which is a benzodiazepine.
Article content
Mounties say this is the first recorded instance of Bromazolam in Alberta. The drug has previously been linked to nine fatal overdoses in New Brunswick in 2022.
The pills seized in Alberta were oval-shaped and stamped with “20” and “SS,” though Mounties say it can come in other forms.
Naloxone treatment, given in many cases of opioid toxicity, is not effective in reversing the effects of Bromazalam, Mounties said, and therefore, any fentanyl mixed with the benzodiazepine “would see a reduced effectiveness of naloxone, requiring the use of additional doses and may still result in a fatality.”
From January to November of last year, there were 1,706 opioid-related deaths in Alberta, and 57 linked to benzodiazepine, up from 1,375 and 43, respectively, in 2022.
Mounties say officers responded to about 1,100 opioid-related calls for service, last year with a third of those proving fatal. RCMP officers also used naloxone 67 times while in the field, a jump of nearly a third over the previous year.

CFIA continues surveillance for HPAI in cattle, while sticking with original name for disease – RealAgriculture
The Canada Food Inspection Agency will continue to refer to highly pathogenic avian influenza in cattle as HPAI in cattle, and not refer to it as bovine influenza A virus (BIAV), as suggested by the American Association of Bovine Practitioners earlier this month.
Dr. Martin Appelt, senior director for the Canadian Food Inspection Agency, in the interview below, says at this time Canada will stick with “HPAI in cattle” when referencing the disease that’s been confirmed in dairy cattle in multiple states in the U.S.
The CFIA’s naming policy is consistent with the agency’s U.S. counterparts’, as the U.S. Animal and Plant Health Inspection Service has also said it will continue referring to it as HPAI or H5N1.
Appelt explains how the CFIA is learning from the U.S. experience to-date, and how it is working with veterinarians across Canada to stay vigilant for signs of the disease in dairy and beef cattle.
As of April 19, there has not been a confirmed case of HPAI in cattle in Canada. Appelt says it’s too soon to say if an eventual positive case will significantly restrict animal movement, as is the case with positive poultry cases.
This is a major concern for the cattle industry, as beef cattle especially move north and south across the U.S. border by the thousands. Appelt says that CFIA will address an infection in each species differently in conjunction with how the disease is spread and the threat to neighbouring farms or livestock.
Currently, provincial dairy organizations have advised producers to postpone any non-essential tours of dairy barns, as a precaution, in addition to other biosecurity measures to reduce the risk of cattle contracting HPAI.

Canada has seen a concerning rise in measles cases in the first months of 2024.
By the third week of March, the country had already recorded more than three times the number of cases as all of last year. Canada had just 12 cases of measles in 2023, up from three in 2022.
