Biosecurity efforts continue in northern Indiana after a second commercial duck flock in Elkhart County tested presumptive positive for highly pathogenic avian influenza.
The flock has about 6,000 ducks and the Indiana State Board of Animal Health (BOAH) is working to establish a six-mile control area and notify flock owners.
A flock of about 4,000 ducks tested positive for HPAI on April 8. Public Information Director Denise Derrer Spears says the first round of testing in that control area is complete.
