Cows are eating chicken what?

The new FDA is getting back in the business of protecting consumers after an eight year drought.
This sounds like a reasonable request to me.
I don't eat at McDonald's, but kudos for joining the call for change.
A large buyer like that carries a lot of weight which in this case, is good news.

A coalition of food and consumer groups that includes Consumers Union and the Center for Science in the Public Interest has asked the Food and Drug Administration to ban the practice of feeding chicken feces and other poultry farm waste to cattle. McDonald's Corp., the nation's largest restaurant user of beef, also wants the FDA to prohibit the feeding of so-called poultry litter to cattle.

Members of the coalition are threatening to file a lawsuit or to push for federal legislation establishing such a ban if the FDA doesn't act to do so in the coming months.
