Organic milk comes from organic cows and federal regulations and requirements are strict. Treating cows with hormones, including Bovine Growth Hormone, rBGH, is strictly forbidden under organic law. No herbicides, pesticides or chemical fertilizers, ever. Straus Creamery hasn’t used any since the 1980s, long before they formally converted to organic. Some other guys are advertising the “GMO-free” label which, by the organization’s own definition, allows for up to 5% gmo-grain or as much “spent” conventional grain used in making beer (a loophole you might research for yourself). At Jupiter Foods we will be exclusively Straus Dairy sellers.
