Odd that. I've never seen the toxin for sale, just the live organism.

Just to be nitpicky, the name "Bt" as used by farmers is shorthand for "Bt toxin" which is short for "Bacillus thuringiensis toxin." The bacterium makes a protein which is toxic to certain insects. It's "toxic" because it binds to a particular protein in the guts of the larvae of some insects and prevents them from functioning properly. If your gut doesn't have that protein that's succeptible to Bt, Bt is not toxic to you. Farmers generally spray the protein, not the bacteria themselves. Nowadays, some crops have been genetically modified to express this protein themselves, no spraying required. Of course, insects are evolving resistance to Bt anyway, so both the spray and the transgenic crops will work for only a limited time.
