Growth Hormones rBGH and rBST
Many cows in the US are injected with these genetically engineered hormones to produced more milk quicker. Cows treated with rBST face a nearly 25% increased risk of clinical mastitis, a 40% reduction in fertility and 55% increase of lameness. More mastitis requires more antibiotics, which leads to more antibiotic resistance. With potential links to breast and prostate cancer, it’s no wonder these hormones are banned in over 100 countries around the world. But for some reason, it’s totally acceptable to use them in the United States. Look for products stating specifically that they don’t add these hormones.
