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.
