Three commercial meat turkey flocks in Missouri have been infected with highly pathogenic avian influenza (HPAI).
The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported that the presence of HPAI was confirmed on three premises in Dallas County on February 21.
The largest of the three flocks had 31,000 turkeys while the smallest flock had 12,300 turkeys involved. Collectively, 71,800 birds were lost. According to the Missouri Department of Agriculture, all three flocks have been depopulated.
Prior to now, Missouri had not had any confirmed cases of HPAI in 2024. The state’s last case was confirmed on November 14, 2023, in Jasper County, with 29,300 turkeys involved. Missouri lost two flocks and 45,900 head of commercial poultry to the virus in 2023. In 2022, the state lost eight flocks and 469,300 birds as a result of HPAI infections. However, prior to now, Dallas County had not had any HPAI infections during the 2022-24 avian influenza outbreak.
So far in 2024, nine states have had HPAI infections in commercial poultry and/or commercial gamebird operations. Kansas has had the most with five, while California has had four, and with these three turkey flocks involved, Missouri has had three. North Carolina and South Dakota have both had two flocks affected, while Colorado, Nebraska, Indiana and Wisconsin have each had one.
In Canada, three provinces have had commercial poultry flocks affected by HPAI. Quebec has had two flock infections, while Ontario and Alberta have each had one.
