The presence of highly pathogenic avian influenza (HPAI) was confirmed in six commercial poultry flocks in the United States on January 22, with four of those being meat turkey flocks in Missouri.
Avian influenza in Missouri
The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported that two of the four recently-confirmed flock infections in Missouri were in Newton County. One of those involved 21,300 meat turkeys and the other involved 23,000.
Also affected by HPAI were a flock of 49,400 turkeys in Jasper County and a flock of 52,400 turkeys in Lawrence County.
Missouri has now had six commercial poultry flocks struck by HPAI in 2025.
Avian influenza in Arkansas
APHIS reported the confirmed presence of HPAI in Cleveland, Arkansas, with a flock of 106,900 broilers involved.
Prior to this, Arkansas’ last instance of HPAI was confirmed on December 30, 2024, in a Clay County broiler flock.
Avian influenza in Maryland
Maryland’s latest case of HPAI involves a flock of 152,000 commercial broilers in Dorchester County.
This marks the fourth commercial broiler flock in Maryland to have the presence of HPAI confirmed in 2025, but the first for Dorchester County.
Situation in Canada
The last case of HPAI to be listed on the Canadian Food Inspection Agency (CFIA) website was confirmed on January 11. That is the source used by WATT Global Media to report new instances of HPAI in Canadian commercial poultry.
A statement on the CFIA website reads: “We continue to experience intermittent technical issues with our website and working to resolve the problem. We apologize for the inconvenience.”
Once those issues are resolved, WATT will continue to utilize the CFIA website as a source.
