Today I heard an ad for a dairy touting the nonuse of growth hormone for their cows. Such ads mislead people to think there is something wrong with milk from cows who do receive the hormone. All cows have growth hormone naturally. When they are given extra, it doesn't change the milk but simply allows the cows to produce more. This allows farmers to use less land, feed and fuel, blessing the world with less-expensive milk.
The FDA states that milk from cows treated with rbST is just as safe as milk from nontreated cows. Stores and dairies know this, but, still, some give in to political correctness and continue their misleading promotion of milk from nontreated cows.
