(Salem, OR) -- The U.S.D.A. has started a new program to test raw milk for the presence of bird flu in dairy cows. Oregon is one of six states where milk will be tested. Bird flu has resulted in the deaths of millions of domestic birds and was first detected in dairy cows last March. Since then, the virus has been confirmed in more than 700 herds in 15 states, although none are in Oregon. Raw milk testing launches December 16th in Oregon, California, Colorado, Michigan, Mississippi and Pennsylvania.
