Back in 1983, the United States government approved the release of the first genetically modified organism. In this case, it was a bacteria that prevents frost on food crops.
The public should know that the liability issues here have yet to be resolved, or even raised. If you're a farmer and you're growing a genetically engineering food crop, those genes are going to flow to the other farm.
The position I took at the time was that we hadn't really examined any of the potential environmental consequences of introducing genetically modified organisms.
Many of the genetically modified foods will be safe, I'm sure. Will most of them be safe? Nobody knows.
