The FDA (illegally) allows the use of diseased animal carcasses (not for human consumption) as ingredients in commercial pet foods.

3+ billion pounds of animal carcasses are put into pet food each year because it is too expensive to throw the carcasses into landfills or incinerate them.

And I am sure none of that meat makes it into McDonalds or BK or Taco Bell or Hardees etc meats…..

Soylent Green anyone?
