In a Thursday, June 4, 2009 photo, packages of seasoned fish for sale are shown at A-Dong market in Westminster, Calif. State and county authorities are inspecting Asian markets in Southern California to try to weed out the sale of white croaker, which has been contaminated by chemicals released into the Pacific Ocean from the 1950s to the 1970s. The fish is not white croaker, said Lt. Specialist John Fallan of California's Department of Fish and Game, but it can be difficult for consumers to tell the difference. (AP Photo/Nick Ut)
