Avian Influenza (Bird Flu)

More Cattle Herds in Michigan Test Positive for Bird Flu

According to WOOD, three more dairy herds in Michigan have tested positive for avian influenza bringing the total of infected herds to 21. More herds in Clinton and Ionia counties now have the virus. Calhoun County has reported its first case of cattle with the virus.
