Because of ammonium hydroxide use in its processing, the lean finely textured beef by BPI is not permitted in Canada.[8] Health Canada stated that: “Ammonia is not permitted in Canada to be used in ground beef or meats during their production” and may not be imported, as the Canadian Food and Drugs Act requires that imported meat products meet the same standards and requirements as domestic meat.[8][9] Canada does allow Cargill’s citric acid-produced Finely Textured Meat (FTM) to be “used in the preparation of ground meat” and “identified as ground meat” under certain conditions.

It’s specifically because of the ammonia, apparently? Idk I feel like I don’t want to learn more because only horrors await me.
