Avian flu is hitting California’s San Joaquin Valley hard — nearly 20 million chickens, ducks and turkeys have been killed in the region since 2022, according to data from the Centers for Disease Control and Prevention.

The ongoing bird flu outbreak has led to wild bird deaths, slaughtered livestock, and hazardous conditions for dairy industry workers.

This is the third case of avian influenza uncovered in commercial poultry in Mississippi since the spring of 2023.
