Which ever you choose, I personally would make sure it was organic. If you don't you could be feeding your child growth hormone, antibiotics, and GE corn (what the animals eat.) Also, if you buy from someone like Trader Joe's you can find the kind without nitrates (cancer causing preservative.) If you can't do that then I would suggest the turkey would be the least contaminated. I have been studying nutrition and food contamination for years, but this is still only my opinion. Also, if you don't buy organic fruit and vegetables use a spray to clean your produce and rinse. Apples are the most pesticide sprayed fruit there is followed by broccoli. Sprays can be found at your grocery store. Good luck, eating clean food goes a long way to staying healthy. Hope this helps. K.
