These numbers are much lower than some of the others, but they are not only in processed food.
They're not "ultra-processed" or "ready to eat", but they're definitely processed foods.
Meat and dairy are heavily processed foods, and plastics are likely the least concerning thing about consuming them.
I would consider ground beef less processed than that, since it does not require a detox step (though it may be wise to cook it before consumption)
Processing means stuff being added and/or removed. Cows, or as they are euphamistically known as "beef", have all sorts of vitamins, growth hormones and other disgusting shit (often literally) added to their diet and bodies. It also has to be cooked, usually in oil, which generates even more Maillard reaction, and thus cancers, etc.
Almost all animal products can be considered ultra-high processed. It's on an entirely different level than whole fruits and vegetables.
