The state of Alabama is investigating suspected cases of bird flu in three northern poultry flocks and has introduced some restrictions on the transportation of birds, reports Bloomberg News. Last week, a commercial chicken flock in Tennessee, located near the Tennessee-Alabama border, was destroyed after testing positive for the highly pathogenic strain of avian influenza.
A commercial chicken-breeding farm in Lauderdale County and a backyard flock in Madison County are among the facilities under investigation, the Alabama Department of Agriculture & Industries said in a statement Tuesday. The state is also probing a flea market in Jackson County and has issued an order limiting the movement of some poultry.
