Luvs, it's not illegal to slaughter for human consumption, it's illegal to sell horse meat for human consumption, because the meat hasn't gone through the USDA inspection process.
I can still slaughter for personal consumption, just like I can eat deer or have a personal cow, pig, chicken, etc. slaughtered for my own use.
For some reason people think because the funding was pulled, that means the consumption of horse meat by humans in the U.S. Is illegal. It's not.
I have a local slaughter house. If I took any of my horses there and said I wanted it processed and turned into chops, steaks, and ground meat, they'd do it. I just couldn't sell the meat to anyone.
Yes, some states have made it illegal to slaughter and eat equines, but the majority of the U.S. States have no such laws on the books.
