rBST is an artificial hormone that can be used to treat dairy cows to increase milk production. Injection with rBST also increases production of another hormone (IGF-1) that is present in both cows and humans. Too much of IGF-1 has been linked to increased risk of cancer. Injection with rBST increases the chances that the animal will get mastitis (infection of the udder) that will have to be treated with antibiotics. This whole process is not healthy for the cow and could also increase antibiotic resistance in the microorganisms in both cows and humans.
