For nearly twenty years, rbGH (recombinant bovine growth hormone), also known as rbST (recombinant bovine somatotropin), has been a staple in the dairy products consumed by Americans. Since these products are not labeled as containing rbGH / rbST, most consumers have no idea that a growth hormone intended to induce dairy cows to be more productive is in much of their milk, cheese and yogurt. After approving the use of rbGH in 1993, the U.S. Food and Drug Administration (FDA) turned a deaf ear to the appeals of consumers, food safety organizations and scientists to reverse its approval of the hormone, or to simply require labeling of foods containing rbGH. The FDA’s decision stood despite regulatory bodies in both Canada and Europe rejecting the hormone due to numerous animal and human health concerns.
