Evidence that GM toxins do not only affect targeted organisms – estimate at least 250 different pathways through which a secondary consumer could be affected by the Bt toxin.

April 28, 2013

there is evidence that the toxins are not as specific as once thought. Adverse effects to non-target organisms can occur through three different pathways: A) through exposure to the toxin in the transgenic plant, in plant secretions, in herbivores, or in herbivore excretions; B) through exposure to metabolites of the Bt toxin; and C) through interactions of the Bt toxin and other plant or herbivore compounds that alter plant or herbivore composition or physiology (Andow & Hilbeck 2004). The number of different pathways is immense- Andow & Hilbeck (2004) estimate at least 250 different pathways through which a secondary consumer (e.g., a carnivore or detritivore) could be affected by the Bt toxin.
