British chef and American t.v. star Jamie Oliver is on a mission to end the unwholesome foods that are bulking up school kids and their parents. They are listening.  After he called attention to "pink slime" in burgers in one of his shows (below), McDonald's felt the pressure. It accelerated its announcement that it had already ended these "boneless lean beef trimmings" since last August.

These trimmings, which consist of what's left of the meat after all the choice cuts of beef are taken, are banned for human consumption in the U.K, where they are instead used for dog and chicken food. They are legal for consumption in the United States, however, where they are treated with ammonium hydroxide in order to kill off bacteria such as E. coli and make it safe for human consumption. - ABC

The operational problem for McDonald's is that the pink slime interferes with McDonald's ability to supply a uniform burger around the world. "This decision was a result of our efforts to align our global standards for how we source beef around the world," replied a spokesperson for McDonald's in a statement.
