North America sees encouraging pause in HPAI outbreaks

HPAI

In a significant development for poultry health and biosecurity, the United States has gone over one month without any new cases of highly pathogenic avian influenza (HPAI), while Canada has marked three months free of commercial flock infections. This pause in outbreaks offers a moment of relief for poultry producers and health officials across North America.

Canada’s last commercial HPAI case was reported on May 2 at a turkey and duck farm in Wallace, Manitoba, affecting approximately 14,400 birds. While several backyard and non-commercial farms saw infections in May, the final case was confirmed on May 15 in Kings County, Prince Edward Island. According to the World Organisation for Animal Health (WOAH), zoning and movement restrictions have been lifted in all provinces except British Columbia and Manitoba. Quarantines have also ended in most regions, with exceptions in British Columbia, Manitoba, and Prince Edward Island.

However, experts caution that vigilance must remain high. HPAI continues to circulate in wild bird populations, which pose an ongoing risk of reintroduction to domestic flocks. Surveillance, rapid response capabilities, and strict farm-level biosecurity remain essential to prevent future outbreaks.

As the poultry industry monitors the situation closely, the recent calm offers a chance to assess preparedness strategies and reinforce defenses. For now, both the U.S. and Canada can cautiously celebrate a period of stability in their fight against avian influenza.
