They put on the side of their milk cartons: "We pledge not to treat our cows with the growth hormone rBST. They were required by the government to attach the a label that states: " *No significant difference has been shown between milk derived from rBST-treated and Non-rBST treated cows." Such a load of lies are government puts out there. Thanks Walmart and Monsanto for lobbying are corrupt politicians, you crooks! We need to work hard to get these laws repealed.
