rBGH: recombinant bovine growth hormone
Cows may be treated with a compound called recombinant bovine growth hormone rBGH.
Canada has banned the use of this hormone in cows, based on research from Canadian scientists. Their report on rBGH noted that cows injected with the growth hormone reportedly have a 25 percent increase in risk of mastitis, an 18 percent increase in the risk of infertility and a 50 percent increase in the risk of lameness. The best way to ensure that you buy milk that has not been treated with rBGH is to buy organic dairy products.
