(Radio Iowa) - Iowa Secretary of Agriculture Mike Naig says U-S-D-A scientists have collected data from Iowa and are working to understand how bird flu has moved to infect dairy cows as well as other animals.
No other state is doing testing of dairy operations within a 12 mile radius of any poultry flock that has to be euthanized after avian influenza is confirmed in the birds.
Some wildlife in those zones are being screened for bird flu as well. Naig says all the data that's being collected may yield specific strategies farmers can use to protect their operations.
