Biotech giant Monsanto is suing a small milk producer in Maine, Oakhurst, that advertises its milk contains no artificial growth hormones. Monsanto claims the advertisements give the public the impression artificial growth hormones are not safe. And Monsanto claims that by doing this Okhurst is directly disparaging Monsanto’s product Posilac, the only artificial growth hormone on the market.

Monsanto boasts the hormones help cows produce up to 15 percent milk, but there are concerns of the effect on the hormones on both the cows and humans. The president of Oakhurst responded by saying, “We ought to have the right to let people know what is and is not in our milk.”
