According to
http://www.factoryfarmmap.org/#animal:layers;location:US;year:2012 the closest CAFOs are in North Louisiana, where the Yankees and carpetbaggers live. All joking aside, I am ashamed that we have any CAFOs in Cajun land. In Lafourche Parish, we still have local meat markets, and our grocery stores get their cattle and produce from local farms. I have never seen a sticker or note that the beef was corn fed, but I will be on the look out for it from now on.
