ST. PAUL, Minn. (AP) _ Minnesota animal health officials are imposing a ban on all poultry sales and exhibitions through the month of April after the presence of bird flu was found in the state.

The ban, which includes poultry community sales, swaps, fairs, exhibitions and other events where birds are brought together, is effective Friday and lasts through May 1.

A report from the Minnesota Board of Animal Health says avian influenza has been found in commercial flocks in Meeker, Stearns, Kandiyohi and Lac Qui Parle counties and in a backyard producer in Mower County.
