Alberta poultry farmers brace for spring migration after last year's surge in avian flu cases
CBC
Spring is heralded by the return of geese, but to many in Alberta's poultry industry, migration means something different.
With last year's avian flu season considered the worst in years, producers like Wetaskiwin-area turkey farmer Scott Olson are being mindful.
"I'm very conscious of not going out in the sloughs or doing anything where migratory birds are hanging out, and then going to our facility," Olson said.
"With this nice weather we're seeing, the geese will be here shortly."
Olson's no stranger to the damage done by avian flu: he's experienced three outbreaks since 2022. The most recent was last fall, and all three cases led to the Canadian Food Inspection Agency (CFIA) culling his birds.
"It happens in one barn, and it will jump to another one a day or two later," Olson said.
"When you contact CFIA, they want to stamp out all the birds on the premises, just to to stop the spread of the avian influenza."
More than 2.5 million birds in Alberta — and 17 million across Canada — have died as a result of avian flu outbreaks since December 2021.
Avian influenza is naturally carried by wild birds. It's spread through saliva and excrement, which can contaminate water and soil when birds fly overhead or make direct contact on the ground.
For farmers like Olson, precautions to avoid avian flu include biosecurity measures like establishing controlled access zones around and within barns, strictly controlling who and what enters each barn, and thoroughly cleaning and disinfecting wherever necessary.
Olson's strict rules also include dedicated boot rooms for changing into barn-specific coveralls, boots, and gloves before entering facilities.
During peak migration seasons, he will also limit farm access to essential vehicles and restrict visitors to mitigate disease transmission risk.
"Hopefully I'm not contaminating anything going in, and I'm not bringing anything back out," Olson said.
In Alberta, there were 26 cases of avian influenza confirmed in flocks last year.
