Here's some other interesting links on the topic:

And to Hank, I regularly see postings from UK etc with information that's useless to us here in the US. If it really bothered me I have the option to see only US questions! Since you are angered by US questions mayhaps you should exercise your option to see only questions from your home country!
Looking at the links above that I collected in just a few minutes it really does seem there is a serious flaw with the US meat industry.
Glad I'm a vegetarian
