    McDonald's said recently that it would begin using chicken from birds that are not raised withantibiotics used to treat humans.

    It also announced that later this year, McDonald's would give customers the choice of low-fat and chocolate milk from cows that have not been treated with the artificial growth hormone, rBST.

    Because McDonald's, one of the largest buyers of chicken in the United States — sells more chicken than beef, the move is likely to have a major impact on the way poultry is raised and the kind of chicken served by restaurants.
