An outbreak of avian influenza has been detected at a poultry farm in Jefferson County, Wisconsin, ProAgro Group reports.
According to the Animal and Plant Health Inspection Service (APHIS) of the U.S. Department of Agriculture (USDA), the virus was found at a farm housing 1.22 million laying hens. All birds will be culled to prevent the spread of the disease, while the poultry houses have been placed under quarantine to restrict the movement of poultry and poultry products.
According to WATTPoultry, the Wisconsin Department of Health Services and the Jefferson County Health Department are monitoring farmers who had contact with infected birds for symptoms of highly pathogenic avian influenza.
APHIS reported that this is the first poultry farm in Wisconsin affected by avian influenza in 2026. Last year, two outbreaks were recorded in the same county, leading to the culling of more than 3.5 million birds.
In 2026, bird flu cases were also reported in Delaware (Kent County), where 147.9 thousand broilers were affected.
In Indiana, the disease was detected at two duck farms with 3,800 and 6,300 birds respectively.
In addition, three farms in Maryland reported outbreaks in late February, affecting nearly 60 thousand chickens.
Since the beginning of 2025, avian influenza has also been detected at farms in Pennsylvania (157 thousand broilers), South Dakota (50.4 thousand turkeys) and Kansas (24 thousand chickens).
Earlier it was reported that the Ukrainian agricultural holding Avesterra Group (brands Epikur, Chebaturka, Delika) plans to invest around €300 million over the next five years in expanding poultry production and building a biomethane plant.
