Would you just calm down? It's only a little poison. That's the official position of the FDA:
The Food and Drug Administration says some chicken meat may contain small amounts of arsenic, though the agency is stressing that the amount is too tiny to be dangerous to people who eat it... a new study by the agency shows that an ingredient in chicken feed that contains arsenic, called Roxarsone, may make its way into parts of the bird that are eaten... Pfizer, which makes the feed ingredient, said Wednesday that it will pull it off the market in the United States. The FDA said it would be banned because it is a carcinogen - USA Today
From Natural News:
...Chicken litter containing arsenic is fed to cows in factory beef operations. So the arsenic that's pooped out by the chickens gets consumed and concentrated in the tissues of cows, which is then ground into hamburger to be consumed... What's astonishing about all this is that the FDA tells consumers it's safe to eat cancer-causing arsenic but it's dangerous to drink elderberry juice! The FDA recently conducted an armed raid in an elderberry juice manufacturer, accusing it of the "crime" of selling "unapproved drugs." (http://www.naturalnews.com/032631_e...) Which drugs would those be? The elderberry juice, explains the FDA.
