Easy solution, just stop eating that crap after all, and you are fine.
If I ever eat meat or fish, I just go to the freaking farmer and buy it directly from him, he can tell me where it came from and I know what I get. Not the most practical solution for everybody, but it works for me.

Things like fuel, maintenance, taxes, license fees are making this more expensive and less cost-effective, year-to-year...even if you are trying to *protect* your food source for purity.

This is actually easy to do, at least as far as the meat is concerned. Growing up, we’d contact a man in the country and buy one of his calves, let him raise it, at slaughter time we’d come for our side of beef and he kept the rest. There are a lot of small operations not too far from major cities where families keep a few dozen head.
