As a random aside, I picked up a meat grinder for my stand mixer and making my own sausage from super high quality ingredients then freezing a ton was an awesome way to get preservative free, delicious pork and lamb sausage for about three months in a single afternoon.
It was maybe a bit much to try ten pounds grinding my first time making but the results were very yum.
Not just from a lab, but those powders which it contains may come from China, where regulations may be lacking.
