The video starts with the meat being inspected as it makes its way to the grinder.
Then the meat goes through the grinder...
...where it gets formed into patties.
Then the patties head to the factory's giant "spiral freezer," which makes them ready for shipping.
Cargill also has an on-site food technician to test out batches of frozen patties.
And that's the whole process, according to McDonald's.
After that, the patties are shipped out, end up at a McDonald's location and cooked there.
In the video, the host Imahara is shocked by the simplicity of the whole operation. But it's been pointed out that the video does leave out some problematic things about McDonald's meat.
Online, McDonald's answers some questions about its products. So far, I didn't see any questions (or answers) about antibiotic use or whether its eggs are cage-free, even in its section on "sourcing and sustainability." Here's what they do answer. On beef hormones: "Most of the cattle we get our beef from are treated with added hormones, a common practice in the U.S. that ranchers use to promote growth." On feeding animals GMO feed: "Generally speaking, farmers feed their livestock a balanced diet that includes grains, like corn and soybeans. Over 90% of the U.S. corn and soybean crops are GMO, so cattle, chickens and pigs in our supply chain do eat some GMO crops."
