Something not processed "for human consumption" may be perfectly fine for people, it's just not being processed in the highly sterile environment that people require. Take the stuff out of the dog food factory and process it using "human consumption" standards and it very well could be just fine.
What is so all fired wrong about this crap anyway? That it "Looks" like crap? Have you seen a dead cow lately? Or is it the name "pink slime"? or just the fact that it is lower quality cuts?
Just what do you people think is in that Jack-In-The-
Box burger? You think they are grinding up USDA choice sirloin?
Look, I understand the yuck factor. I get it. There are LOTS of foods that make me gag just thinking about it. So I don't buy Clams, or canned tuna, or hamburger, sardines, or other things that I am not comfortable with. That doesn't mean I don't think ANYONE should be able to buy it.
Removing this option will cause hamburger to be more expensive meaning that there will be families that can no longer afford it. YOUR yuck factor has just caused a family to have to go without meat this week.
Study it. Learn what it is about. Find out if it is ACTUALLY unhealthy... if it is then ban it and sue people. But apparently the FDA has done those studies already and called it good.
