The highly pathogenic avian influenza (HPAI) outbreak in North America is again intensifying, with new cases being confirmed in commercial poultry in both the United States and Canada.

Federal agencies have reported new cases in Manitoba, Canada, and Minnesota, United States.

Avian influenza in Manitoba

HPAI was detected in a commercial poultry flock in Manitoba, making it the fourth province in Canada to have a new confirmed case within the past week.

Manitoba’s latest case of HPAI was confirmed on September 14 in the Rural Municipality of Cartier, according to the Canadian Food Inspection Agency (CFIA). Specific details regarding the species in the flock or the number of birds affected were not made available.

This is the first case of HPAI in Manitoba since June 15, but the first one in commercial poultry since April 23. So far in 2022, Manitoba has only had the two cases in commercial poultry, and two other cases in backyard poultry.

The Manitoba case follows cases confirmed on September 12 in three other provinces. Two cases were confirmed in Alberta, while one case each was reported in Alberta and Saskatchewan.

Two new HPAI cases in Minnesota

The same day the new Manitoba case was confirmed, the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported two new confirmed cases of HPAI in Minnesota.

The new cases involved 63,600 meat turkeys in Meeker County and 8,500 turkey breeder hens in Otter Tail County.

According to APHIS, this is Meeker County’s eighth HPAI case in 2022, with half of them occurring since August 28. The Otter Tail case marks that county’s fifth case of the year, with the previously most recent case being confirmed in late April.

The number of commercial poultry flocks in Minnesota to be affected by HPAI in 2022 now stands at 66.

Minnesota and Manitoba share a border.
