Arsenic in Chicken

Another one of those oh my moments, reading this article about how the arsenic in chicken feed is getting into the waterways...never mind the idea that we feed arsenic to chickens in the first place. Eventually the article gets around to explaining the difference between organic and non-organic arsenic, and how it's only the non-organic kind that's dangerous. And then mentions how natural organisms are converting the organic arsenic into non-organic (aka deadly) forms in the environment. Of course, at perfectly safe levels. They say.
