The Washington Post is reporting that McDonalds restaurants is asking their meat suppliers to cut back on the use of antibiotics.

The move comes as a reply to the growing concern that antibiotics in the food chain are contributing to the increase in antibiotic-resistant bacteria, a growing health concern.

McDonald's is the countries largest purchaser of beef products and near the top for both chicken and port, so they tend to have large sway over what is done in the market.
