Summary. The available evidence shows that the use of rBGH can cause adverse health effects in cows. The evidence for potential harm to humans is inconclusive. It is not clear that drinking milk produced using rBGH significantly increases IGF-1 levels in humans or adds to the risk of developing cancer.

Likewise, do cow hormones affect humans? Recombinant Bovine Growth Hormone (rBGH) However, the FDA concluded that there is no evidence that a biologically active form is absorbed. Also, the bovine growth hormone is not active in humans. If this is true, even if it was absorbed by humans, it would not be expected to affect health.

Also know, is rBST legal?

RBST, short for recombinant bovine somatotropin, is a type of artificial growth hormone that increases milk production. It is illegal for use in Canadian dairy cows, but is legal in the USA.
