Iowa Secretary of Agriculture Bill Northey has highlighted the continued biosecurity efforts by Iowa turkey, egg and broiler farmers and the preparations undertaken on the state and federal level following the confirmation of highly pathogenic avian influenza in Tennessee and low pathogenicity avian influenza in Tennessee and Wisconsin in the past week. Highly pathogenic avian influenza virus strains are extremely infectious, often fatal to domestic poultry, and can spread rapidly from flock-to-flock.
