13. Is McDonald's beef grass fed?

McDonald's doesn't guarantee that its beef is grass fed, though the company assumes at least some of its cattle spend time grazing before heading to a feed lot to be finished on grain.
"Farming practices vary, but generally much of the cattle in the U.S., including the cattle we use for our beef, are grass fed for the first part of their lives," McDonald's USA writes. "When cattle enter feedlots in the latter part of their lives, they are provided a balanced diet that may include grains, grasses and mineral blends in their feed."
