The free range chicken debate has had a bit of media exposure over here recently. That said I can't see anything being done about it.
As for the hamburgers/mince meat, who eats that crap anyway?
The same could be said for the rest of the whole article, if you are aware what is going into foods and actually take time to read the labels, you would probably avoid a lot of those issues. Even better if you do things like make your own bread and OJ like someone else mentioned. To me it all boils down to people being ignorant about food choices and even more ignorant about what a healthy (read mainly unprocessed foods) diet means.
