In Canada, government scientists have discovered a report by the Monsanto Corporation, makers of Bovine Growth Hormone (BGH) which stimulates milk production in dairy cows. The document indicates that the hormone may be linked to certain thyroid and prostate diseases, and could be implicated in some cancers. The Food and Drug Administration (FDA) first approved use of BGH back in 1933, and since then, about one in every three cows has been given the genetically engineered milk production stimulant. Steve Curwood speaks with Dr. Michael Hansen, a researcher at the Consumers’ Union in New York about what has recently led activists to petition the FDA for a BGH ban.
