As Alberta's chief veterinarian, Dr. Keith Lehman is keeping a close eye on the U.S. dairy cattle outbreaks.

"[I'm] certainly concerned because we've seen the impact that it can have in the United States," he said in an interview.

According to Lehman, H5N1 has been identified in 82 Alberta poultry establishments, ranging from commercial farms to backyard flocks, since April of 2022. That includes two in February of this year. All impacted flocks have been culled.

But it has not been identified in any Canadian dairy cattle.

"Knowing that [there was] a single point of introduction from wild birds, knowing that we've put import controls nationally that require testing of cattle coming up from the U.S., I think our risk of introduction into the Canadian herd is really dramatically reduced," he said.

Alberta confirms 5 cases of avian flu spreading to mammals

Alberta now has five confirmed cases of avian flu that have spread from birds to mammals.

Five skunks from central Alberta have been lab-confirmed as having avian influenza.

“We had an unusually large number of calls about skunks that were acting strange or being found dead and it was all within the area where we had confirmed that the avian influenza virus was present in the snow geese,” Dr. Margo Pybus, a provincial wildlife disease specialist with Fish and Wildlife Alberta Environment and Parks, said.

“We believe that the skunks are feeding on the dead geese and they are getting enough virus that it’s actually affecting the skunks.”...

Alberta is the latest Canadian province to have found avian influenza, or bird flu, in another species.

Cases of bird flu have been confirmed in skunks in the Vegreville-Wainwright-Lloydminster area in east-central Alberta, according to the province's wildlife disease specialist.

"[Avian influenza] was brought into the province in early April in migrating waterfowl, primarily the geese. As a number of geese died, we started getting reports about a number of dead skunks," Dr. Margo Pybus told CTV News Edmonton.

The skunks tested negative for rabies and positive for bird flu...
