Seems Bt isn't nearly as benign as it's manufacturers, users and proponents would have us believe. How could this be? And it's even used by a lot of organic farmers, being classified as an *organic* pesticide by the USDA.

Jeffrey M. SmithThe biotech industry is fond of saying that they offer genetically modified (GM) crops that resist pests. This might conjure up the image of insects staying away from GM crop fields. But “resisting pests” is just a euphemism for contains its own built-in pesticide. When bugs take a bite of the GM plant, the toxin splits open their stomach and kills them.
The idea that we consume that same toxic pesticide in every bite is hardly appetizing. But the biotech companies and the Environmental Protection Agency—which regulates plant produced pesticides—tell us not to worry. They contend that the pesticide called Bt (Bacillus thuringiensis) is produced naturally from a soil bacterium and has a history of safe use. Organic farmers, for example, have used solutions containing the natural bacteria for years as a method of insect control. Genetic engineers simply remove the gene that produces the Bt in bacteria and then insert it into the DNA of corn and cotton plants, so that the plant does the work, not the farmer. Moreover, they say that Bt-toxin is quickly destroyed in our stomach; and even if it survived, since humans and other mammals have no receptors for the toxin, it would not interact with us in any case.
These arguments, however, are just that—unsupported assumptions. Research tells a different story.
***Bt spray is dangerous to humans
When natural Bt was sprayed over areas around Vancouver and Washington State to fight gypsy moths, about 500 people reported reactions—mostly allergy or flu-like symptoms. Six people had to go to the emergency room for allergies or asthma.<1>,<2> Workers who applied Bt sprays reported eye, nose, throat, and respiratory irritation,<3> and some showed an antibody immune response in linked to Bt.<4> Farmers exposed to liquid Bt formulations had reactions including infection, an ulcer on the cornea,<5> skin irritation, burning, swelling, and redness.<6> One woman who was accidentally sprayed with Bt also developed fever, altered consciousness, and seizures.<7>
