There are no links to any of the studies, nor can I find any studies published in a respectable journal that say any of what that link is stating.
I'm sorry but since the original source material of this I-SIS group is blocked to me I can only argue that the site itself is misleading in order to
promote the organic food industry. Parts of it, frankly, just read as jibberish. Why should I be afraid that pigs were passing DNA and undigested Cry
toxin in their poo? Wouldn't that mean that the genes weren't forcing themselves into any genomes and the toxin wasn't punching holes in the pigs'
Regarding the study that "showed" Bt potatoes causing intestinal damage when ingested by mice, the use of potatoes in the experiment has me
wondering if it was not the result of another toxin? (www.biotech-info.net...
) If this is the study shown in the source, I do not
see any significant harm caused by the diet. Given that the control group in this study is about as bad off as the GM variety, I wonder if there is
any relevance to the studies which show that glycoalkaloids, which are present in potatoes, cause intestinal inflammation and permeability?
It makes me wonder why they would choose to test potatoes in a study of Cry pro-toxin in GM foods when
other sources of GM foods with Bt exist that are not inherently full of toxic compounds naturally and variable in their inherent toxicity. Potatoes,
of different varieties, sources, and ages each containing variable levels of inherent toxins which cause inflammation and other intestinal maladies
does not sound like a very controlled study of the effects of Cry pro-toxin or GM food safety at all!
I can also speculate that, if any of the information regarding Cry toxin dangers to humans were true, that we should be quite afraid of organic
produce given the extent to which they are sprayed with the original bacterium source itself and the wide variety of Cry toxins produced by the
original bacterium. Such fears are not widespread and it is still one of the most widely used and available organic pesticide. I bought some from the
local garden store, unfortunately a bit too late to save last year's tomatoes.
If it is of any interest, this link explains the mode of action of Cry toxin with picture aids, in case anyone likes pictures. I know I do :-)
The Cry toxin protein found in GM crops is a protoxin. It only becomes toxic when degraded by specific enzymes which are specific to a small range of
insects. That is precisely why organic farmers spray their fields with the bacterium, because the toxin harms only the targeted pests without harming
the beneficial insects they seek to cultivate on their fields or the people eating their crops. That is precisely the reason specific forms of the Cry
toxin have been engineered into foods that, after undergoing safety testing and shown to be safe, have been allowed into the food supply.
