Michigan has become the latest state to have a confirmed case of avian influenza, as the USDA’s Animal and Plant Health Inspection Service (APHIS) reported the presence of highly pathogenic H5N2 avian influenza in a wild Canada goose in Macomb County, Michigan.
A sample, taken from a sick bird, was tested by the Michigan State University Diagnostic Center for Population and Animal Health, and was confirmed by USDA’s National Veterinary Services Laboratories in Ames, Iowa.
Avian influenza has yet to be detected in commercial poultry flocks in Michigan, although the virus has hit commercial flocks in Wisconsin, Indiana and Ontario, Canada, all of which border Michigan.
With the latest avian influenza detection, 21 states have now had confirmed cases of the virus. Other states affected by avian influenza include Minnesota, Iowa, North Dakota, South Dakota, Nebraska, Wisconsin, Kansas, Missouri, Arkansas, Wyoming, Montana, Washington, Oregon, Utah, Idaho, California, Indiana, Nevada, Kentucky and New Mexico. APHIS has reported 219 cases of avian influenza in the United States, and those cases have affected more than 46.8 million birds.
