In the early 1980s, four chemical/pharmaceutical companies, Monsanto, Upjohn, Eli Lilly and American Cyanamid began researching a new technology they believed would revolutionize the dairy industry. Through genetic engineering, researchers created recombinant bovine growth hormone (rBGH) to increase milk production in dairy cows by 10 to 25 percent. The FDA approved Monsanto's rBGH product, Posilac, for commercial use on November 5, 1993. Monsanto leads the production of genetically modified seeds and commercial animal stock. Genetically modified food involves the introduction of foreign DNA into plants and animal using the methods of genetic engineering. Genetic modification techniques often involves incorporating bacterial DNA into plants and animals, thus changing their “blueprint” of existence. These changes are much different from selective breeding and mutation breeding. Genetically-modified foods (plants and animals) raise safety issues, environmental concerns, and economic concerns because:
Recombinant Bovine Growth Hormone (rBGH) which is a genetically engineered hormone that is injected into dairy cows every other week to force the cows to produce more milk causes problems that is adverse to milk consumers: Cows get mastitis(infections) in the udder causing pus / white blood cells to be expressed into the milk so that antibiotics used to treat mastitis and pus remain in the milk and drank by the consumer -YUM.
