Bovine somatotropin (BST) is a growth hormone approved for use in the United States to increase milk production in dairy cattle. Currently, its use is banned in Canada. Independent studies completed by the FDA and World Health Organization have concluded that milk and meat from cows treated with BST are safe for human consumption.

Independent studies completed by the FDA and World Health Organization have concluded that milk and meat from cows treated with BST are safe for human consumption.
Researchers have shown that trace amounts of BST can be found in milk and meat produced by BST-treated cows. BST can also be found in milk from untreated cows as it is naturally produced in the cow's pituitary glands. BST has the same function in cows as the human growth hormone (hGH) does in humans.
