Buyer beware is in play as never before. Much of the time we can't discover what is in our food. If you have to use ammonia to kill the bacteria in it I won't buy it. I like beef but not rotten scraps steralized or not made into a paste. Industry is determined to force us to buy what it wants to sell despite our objections. They just won't tell us what is in it. I've broken a tooth on a piece, of bone in meat several years ago and nearly did it a number of times the last several years. Meat is processed in factories and sent to the meat department, even if they have Butchers. I discovered at a Sams Club, last year I think, they wouldn't grind a piece of chuck I purchased from them into hamburger because of regulations on tracking meat. It is all hogwash. I found one market that would do it but it turned out it was already coarse ground when they got it and they regrind it into what most recognize as hamburger.
We have a Butcher near here but at 6.00 per pound of hamburger, we can't afford it often. It's a shame the Dept of Ag is not protecting our Interests or health.
