Why isn milk from BST supplemented cows labeled?
There is no health or safety risk to humans and no difference in milk from cows supplemented with BST and those not supplemented. Therefore, labeling provides no benefit or protection to consumers; however , label enforcement would be costly and extremely difficult. There is no practical way to tell the difference between naturally occurring BST and supplemented BST. Furthermore, it is estimated that initially fewer than 10 percent of cows will be supplemented.
