Our right to know what's in our milk

On Radio Times, January 15, 2008: "The Pennsylvania Department of Agriculture recently ruled that dairies that do not inject their cattle with synthetic growth hormone can no longer label their milk as hormone-free. The decision, which has been put on hold until the beginning of February, raises serious questions for consumers, dairy farmers, and retailers." Pennsylvania would be the first and only state in the nation to enact such a ban. Marty Moss-Coane's guests are Terry Etherton of Penn State University and Michael Hansen of Consumer’s Union.
