Avian influenza detected in Saskatchewan
The last time HPAI was found in Saskatchewan in either commercial poultry or wild birds was in 2007

REGINA — Samples collected from a snow goose found near Elrose have been confirmed positive for HPAI by the Canadian Food Inspection Agency.

The Ministry of Agriculture is reminding poultry producers with flocks of all sizes to follow all necessary biosecurity protocols to keep their flocks free of diseases after a highly pathogenic avian influenza (HPAI) H5 strain was detected in a wild bird in Saskatchewan.

The confirmation of the strain in the Saskatchewan bird follows the detection of HPAI in poultry and wild birds in the United States and in several Canadian provinces.

Deadly avian influenza has been detected in Saskatchewan for the first time in 15 years.

A snow goose near the town of Elrose, around 320 km northwest of Regina, was found to have the “highly pathogenic” H5 strain of avian influenza (HPAI) by the Canadian Food Inspection Agency.

Veterinary pathologist Trent Bollinger performed the autopsy in Saskatoon.

Since then, he said his lab at the University of Saskatchewan has done tests on upwards of 50 birds believed to have died from HPAI. The number of unreported deaths is even higher, he said...

Presumptive cases of avian flu in skunks, foxes found in Sask.
Sun, May 29, 2022, 6:00 a.m.·2 min read

Presumptive cases of avian flu are showing up in some species of mammals in Saskatchewan.

Trent Bollinger is a wildlife pathologist at the Western College of Veterinary Medicine in Saskatoon.

He told CBC News the first presumptive case of avian flu in a "major carnivore" came into the lab about three weeks ago.

As of the last week, six to ten more have been tested.

"These are primarily skunks, with the occasional red fox, that have neurological signs which could be attributed to (high pathogenic) avian influenza virus," he said.

Bollinger noted there are other viral diseases — such as distemper and rabies — that cause similar symptoms in these species...

Suspected cases of bird flu in foxes and skunks

Skunks may have died of bird flu in Saskatchewan.

Possible cases of bird flu have emerged in mammals in Saskatchewan, according to pathologist at the Western Veterinary College in Saskatoon, Trent Bollinger.

According to him, the first suspected case of bird flu in a large carnivore was brought to his laboratory three weeks ago.

As of last week, between 6 and 10 other animals had been tested.

It was mostly skunks, as well as a red fox, that showed neurological signs that could be attributed to avian flu , he says.

Trent Bollinger notes that other viral illnesses cause similar symptoms, such as distemper or rabies.

However, recent molecular diagnostic tests point to avian flu as the most likely cause in at least three of the deaths analyzed.

In other cases, we have done autopsies and we are continuing the analyses. There could therefore be more cases , specifies the veterinary pathologist.

The transmission of the virus to mammals does not surprise the specialist. Cases have also appeared in the United States, he says. But we have quite a few, which may be a little unusual. That remains to be seen.

Deaths throughout the summer

Trent Bollinger expects more waterfowl to die from bird flu over the summer, as the risk of transmission is high in these bird species.

There were a large number of dead birds in the spring, during the migration season. But while the specialist expects the mortality of these birds to decrease during the summer, he notes that the baby birds are however another group at risk.

We will have new cohorts of ducklings and juvenile birds that could also be exposed to the virus, he says. So we could see yet again an increase in the number of dead birds observed by the public.

According to Trent Bollinger, the species most affected by the virus seem to be in relatively high numbers, and the mortality rate does not currently have a significant impact on their populations.

What is especially worrying is the risk of transmission to poultry, because then the birds die in large numbers and the virus has economic impacts , he recalls.

The veterinarian is reassuring: the virus of this flu is not transmitted to dogs, cats and humans.

What to do

Trent Bollinger reminds you to avoid touching animals whose behavior is not normal, and contact a wildlife conservation officer.

If the animal in question dies and avian flu may be the cause, Trent Bollinger says the carcass can be picked up wearing latex gloves, put in a plastic bag and taken to a lab, like that of the College of Veterinarians.

Wildlife rehabilitation centres in Regina, Saskatoon issue warning as bird flu spreads

By Lara Fominoff
May 5, 2025 | 6:00 AM

Saskatoon’s Living Sky Wildlife Rehabilitiation and Regina’s Salthaven West Wildlife Rehabilitation centres are warning the public about handling sick or dead wild birds and mammals as cases of bird flu are on the rise.

Both organizations say they are receiving multiple calls every day about suspected Highly Pathogenic Avian Influenza HPAI (H5N1) in snow geese and Canada geese returning to the province.

Jan Shadick, executive director of Living Sky Wildlife Rehabilitation, said it seems that more snow geese are exhibiting symptoms this year.

“We are definitely getting calls about these birds and it’s not just the geese, because what happens is the virus lives in water quite successfully and so when these birds are migrating through … if there’s one bird on the water, then all the other birds on the water are susceptible,” Shadick explained.

She said it’s not just birds but also predators that are becoming infected with the deadly virus.

“The foxes and the raccoons and the skunks and the coyotes and all of the bird predators — your bald eagles, your hawks, your owls — are eating these carcasses and becoming sick themselves,” Shadick said.

Testing confirms avian flu after hundreds of dead geese found near Lipton, Sask.

3 Sask poultry farms quarantined because of the virus

Colleen Silverthorn · CBC News · Posted: May 23, 2025 6:00 AM CDT | Last Updated: 1 hour ago

Hundreds of dead geese found this spring in fields near Lipton, Sask., 90 kilometres north east of Regina, died from avian influenza, reflecting a provincial uptick in the deadly disease, according to the Ministry of Environment.

Tests completed earlier this month confirm the birds died from H5, the highly pathogenic strain of avian flu.

Iga Stasiak, a wildlife health specialist with the ministry, said there have been several reports this spring of dead flocks of geese. She said that in some cases, there were hundreds of dead birds reported at sites.

"It is actually quite unusual to see this scale of mortality," Stasiak said.

"With this recent strain it seems to affect birds more seriously, so we have seen increased mortality in wild bird populations, which is concerning."
