I am a dairy farmer, I would like to tell you that rBGH/rBST is a naturally occurring hormone that is within all milk. It is a hormone that makes a cow eat, in high producing milk cows it is in larger amounts and in low producing cows it is in a lesser amount. There is NO TEST in the world that can detect rBST or say if it is synthetic. The sad part is, I know an organic farmer that uses rBST because he can have his cows produce more milk, and KNOWS that he wont get caught. He just tells the people if you test for it and I come back positive then I will quit being organic. rBST poses no threat to animal or human I would encourage people to look at the facts before becoming bias on this topic especially!
