"Pink slime" is one of the meat industry's most disgusting creations ever -- and the more people learn about it, the more companies turn away from it.

Even McDonald's has said it won't use this stuff in its burgers anymore.

But thanks to the meat industry's friends in high places there's one place where pink slime is still on the menu every single day: school cafeterias.

Call it one more reason to make sure your kids and grandkids bring their own food to school every day.

If you haven't heard of pink slime yet, prepare to lose your appetite.

As I told you a couple of years ago, this stuff is allegedly beef -- but it's not any cut of meat you'd actually recognize.

It's factory floor meat scraps that would have been tossed into the garbage not long ago.

Because it's so nasty, it has to be heated and treated with ammonia to kill the bacteria crawling all over it. By the time it's done being processed, it looks like... well... the name says it all.

Lately, it's been getting a lot of attention and companies like McDonald's are tripping over themselves to make sure people know they've stopped using it.

In any other circumstance, it would be the end of pink slime. People don't want it... companies won't use it... so the natural laws of supply and demand should kick in.

But these aren't natural circumstances, because the meat industry has a special friend to rescue it in times like this: The United States Department of Agriculture.

While everyone else flees from pink slime, the USDA -- the same group that thinks it has the right to tell you what to eat, by the way -- is ordering 7 MILLION POUNDS of this stuff to use in school lunches.

But the agency says don't worry -- no single school burger will be more than 15 percent slime.

How reassuring.
