Well, rBST is banned in the EU, non on health or safety but on animal welfare grounds, as cow udders are not made for that level of milk production and mechanical milking causes distress and injury (mastitis) to the cows. Also there is a difference between BST (bovine somatotropinnatural) and rBST (r stands for recombinant, the manufacturing process) the synthetic kind. The FDA's "concerns" are transparently based purely on the commercial interests of rBST producers like Monsanto and their customers'.
