rBST-free or rbGH-free. Though cows are not (yet) genetically engineered, many are being injected with a genetically engineered recombinant bovine growth hormone to boost milk production. Though this milk is approved by the FDA as safe for human consumption, so-called recombinant bovine growth hormone (rBGH) or recombinant bovine somatotropin (rBST) has been linked to health problems in cows and remains controversial. It’s been banned in Canada and Europe. When conventional milk producers began labeling their bottles “rBST-free,” agribusiness giant Monsanto (which developed the technology) bankrolled a farmers’ organization that pushed state governments to ban the label. It was unsuccessful and many milk brands now state rBST- or rBGH-free on their labels.
