You view presumably proceeds from the position that genetic
engineering is basically the same as conventional breeding, the same
view I've heard from other pro-GE people. I really wonder how they
justify to themselves this view, given that you can never
conventionally breed a horse with a pig, or a pig with a fish, or a
corn with a bacterium.

Both the FDA and the EPA ruled that since GE-corn (and presumably
GE-soya too, but the documents I have pertain to GE-corn) is
subtantially equivalent to its conventional counterpart, there is no
need for thorough testing. GMO's have, in fact, avoided exhaustive
testing through the "substantial equivalence" shortcut.

You can't say for sure its misplaced because there is no scientific
consensus on the safety issue. Industry said the same thing about
nukes, pesticides, CFCs, etc.

Well, if Pioneer didn't think about these things, I would imagine
there are still other problems they probably didn't think about too!

I can why Pioneer would adopt this legal position, because it means
Pioneer won't be liable for all the genetic contamination. But if
non-GMO farmers lose income because their crop is genetically
contaminated with GMOs, I don't think the *source* of contamination
can dodge responsibility and escape liability. Howerver, this is
something your legal system would have to work out.

I meant feeding tests. I am confident enough to say Pioneer hasn't
done so, because I've really been looking and asking around for
feeding test studies, and I've so far located only 3 that have been
published: Monsanto (<1997, rats), Novartis (1998, broiler chicken)
and Pusztai (1999, rats). If Pioneer has done one, I'll gladly correct
my statement and cite Pioneer's study. I hope you can post the results
here.

I'm starting to repeat myself. I think I'll rest my case.
