not really. obviously we don't know what exactly is going on in the farms and no foods are 100% garunteed safe unless you grew it yourself but generally speaking you just want less processed stuff. Like the chicken quarters are whole meats, where as a burger, or hotdog, or something would be more processed. It's easy to put fillers in without people noticing once the meat is ground up, and reshaped into something else. So like chicken leg is better than chicken nugget. Can't garuntee its 100% natural or anything, but if you get the whole meat, and wash it off well you should be better off than most. Same goes for veggies. Get a whole vegetable, wash it off good, and your in about the best spot possible.

Any food that is like snackified, or made into something already is a lot more likely to have some horrible for you chemical in it.

Oh also something i just thought of to save money. If you make an account at some of the stores (like kroger is one i know does it) and then you dont go there for a long time and go to other stores instead they will mail you some really good coupons. You can also just have 2 accounts and not use one for awhile to trick them. But u usually need multiple phones and addresses. Easy to do if you share accounts with friends and family. I got coupons in the mail from kroger recently that were just 2 free cans of del monte vegetables any variety no pre-purchase or anything required. You get some pretty good ones that way.
