Beef General Information

Where does the bacteria in ground beef come from?

Great care is taken when the animal is killed and butchered to be sure the meat does not become contaminated by either of these sources.

After the hide and intestines are removed the carcass is thoroughly cleaned to be sure there is no "ingesta," undigested material, or "feces", animal waste, left anywhere on the carcass. In the case of dairy cattle, used primarily for ground beef products, the udder must be carefully removed making sure there is no leakage causing possible contamination.
