I was reading in one of the recent jewish weeklies, about cholov yisrael cheese making and the article mentioned something about cows that had some kind of surgery that made those cows not halachally permissible to use the milk from. The CY companies do not use these cows that had the surgery. Being that is the case, and the CS companies use these surgically altered cows, definetly makes the case for myself to use only CY products.
