In the US, we saw a tipping point against Monsanto’s genetically engineered bovine growth hormone (rBGH) when it got kicked out of Walmart, Starbucks, Yoplait, and Dannon.

This was not due to any action taken by the Food and Drug Administration (FDA), but occurred when mothers across the nation became aware of the cancer risks associated with milk from cows treated with bovine growth hormone.

Now, the tipping point of consumer rejection of genetically engineered foods in the US is almost here.
