In the United States, USDA regulations stipulate that AMR machinery cannot grind, crush, or pulverize bones to remove edible meat tissue, and bones must emerge intact. The meat produced in this manner can contain no more than 150(±30) milligrams of calcium per 200 grams product, as calcium in such high concentrations in the product would be indicative of bone being mixed with the meat. Products that exceed the calcium content limit must instead be labeled "mechanically separated beef or pork" in the ingredients statement.
