Organic cow’s milk would cover many, if not all, of these bases as well. The extra hormone (like estrogen) is given to help the cows breed and/or produce more milk. Hormones, antibiotics, and chemicals of any sort are not used in organic milk production. As I understand it, if an animal needs medical treatment, i.e. pain killers, antibiotics, her milk cannot be sold as “organic” for a specified period of time. Of course, you’d want to make sure your milk was certified and also from a reliable, organic source.
