American Samoa was the world's fourth-largest tuna processor in 1993. The primary industry is tuna processing by the Samoa Packing Co. (Chicken of the Sea) and StarKist Samoa, a subsidiary of H.J. Heinz. The first cannery was opened in 1954. Canned fish, canned pet food, and fish meal from skin and bones account for 93 percent of American Samoa's industrial output.
