I avoid McDonald and I avoid chicken meat, in Europe chicken get 10 or more different antibiotics, just below each maximal permissable value (by law) /Grenzwert , but the sum is not controlled. The unlucky human, who dares to eat this meat gets health problems and antibiotics will not work for them any more. There should be someone to measure the amount of antibiotics in the meat.
I hope that the situation is better with chicken raised in an organic farm, outside in a spacious garden with grass and trees.
