The turkey industry lost 545,100 birds to highly pathogenic avian influenza (HPAI) during September 2026. This uptick aligns with the seasonal autumn upsurge of the virus observed in commercial and backyard flocks.
Why it matters
Understanding these HPAI outbreaks is critical as they reflect the persistent vulnerability of the commercial poultry industry to recurring viral waves. Tracking these patterns helps stakeholders gauge the ongoing impact on agricultural stability and food supplies.
Minnesota turkey farms suffered significant losses of 320,000 birds across seven distinct sites in September. Canada also reported nine commercial poultry outbreaks between September 10 and September 30, 2026.
The players
APHIS
The Animal and Plant Health Inspection Service is the federal agency responsible for protecting U.S. agriculture from pests and diseases.
The details
The virus affected a wide range of livestock, including commercial meat duck farms in Jay County, Indiana, and dairy herds in both Texas and Idaho. APHIS records indicate these infections followed a period of relative quiet after the last major turkey flock outbreaks in May 2026.
Timeline
August through December 2025: The industry lost more than 2 million turkeys.
May 2026: This marked the final reported turkey flock infections before the August 2026 cases.
August 2026: South Dakota turkey farms reported confirmed HPAI cases.
September 2026: Turkey growers lost 545,100 birds.
September 10-30, 2026: Canada confirmed nine outbreaks in commercial poultry flocks.
Culture Shift
This recent spike follows the seasonal pattern of an autumn upsurge in HPAI activity observed in recent years. The current trends mirror historical cycles where cooler migratory months trigger widespread viral transmission across North American poultry populations.
These industry-wide losses may affect retail pricing and availability for consumers purchasing poultry products during the autumn months. Bird watchers and hobbyists should remain aware of local advisories, as increased HPAI activity can lead to restrictions in parks or wildlife refuges.
The takeaway
Maintaining strict biosecurity measures remains the most effective defense for poultry owners during seasonal viral peaks. Staying informed through official state and federal agricultural bulletins helps mitigate risk for both commercial growers and private hobbyists.
