  •  Do you have a working link to the actual data? (10+ / 0-)

    The link in the body gives me " Not a .pdf or corrupt" error.
    I did find

    The peer-reviewed study, conducted by a team of researchers at the University of Caen, found that rats fed on a diet containing NK603 Roundup resistant GM maize, or given water containing Roundup at levels permitted in drinking water, over a two-year period, died significantly earlier than rats fed on a standard diet.

    Up to half the male rats and 70% of females died prematurely, compared with only 30% and 20% in the control group. Across both sexes the researchers found that rats fed Roundup in their water or NK603 developed two to three times more large tumours than the control group. By the beginning of the 24th month, 50-80% of females in all treated groups had developed large tumours, with up to three per animal.

    So Rats that are fed Round-up develop tumors? Not surprising.
    So far, I can't find anything that says that the group which was fed Round-up resistant corn, seperated from the rats that were fed plain old roundup, developed more tumors.

    Umm, sure, Glycophosphate causes tumors in rats.

    But the actual corn doesn't contain glycophosphate.

    I'm hoping the press got this wrong- because a study that lumps the two groups ( +GMO and +Glycophosphate) as the same sample set isn't just badly designed, it's dishonest.

    •  I should look this up, but IIRC (7+ / 0-)

      Round-uP contains glycophosphate AND an "inert" ingrediate.

      Somewhat strangely, previous studies have shown that it was the "inert" ingredient that is what is deleterious to the health of mammals . .. .

    •  The rats were fed levels of Roundup (6+ / 0-)

      permitted in drinking water. The text you quote does not mix the corn-fed and Roundup-fed results, it states that both led to increased tumor numbers.

      You're right - that link is wrong. I just contacted the person that sent me the link and urged her to find out was happening and to correct it.

      But the actual corn doesn't contain glycophosphate.
      Why not?

      According to Wikipedia, glyphosate competitively inhibits the enzyme 5-enolpyruvyl-shikimate-3-phosphate synthetase. The GMO corn presumably overcomes the inhibition by, as you mentioned, expressing more of the enzyme (or a resistant mutant). The enzyme does not degrade the glyphosate, as far as I know, it just makes the plant tolerant of it. So glyphosate that enters the plant is presumably there when the plant is harvested, depending on its persistence from the time of application.

      Is this correct?

      •  or the bacterial enzyme is Roundup resistant. (4+ / 0-)

        Doesn't matter, why would Roundup not be present in the GMO plants? It has to enter plants to be effective (it inhibits aromatic amino acid synthesis), so if it didn't enter the plants, one wouldn't need to give the plants the bacterial gene.

        It appears that feeding the rats GMO, Roundup-treated maize may be a way of dosing them with glyphosate.

        •  If that's true (1+ / 0-)

          Then it would imply that we're probably also dosing ourselves with glyphosphate.

      •  I've been trying to hammer on this for years (0+ / 0-)

        Of course the harvested plant sprayed with Roundup would contain some level of glyphosate and the highly toxic surfactant POEA incorporated into its structure. Let's think about it.  All the plants sprayed with RoundUp absorb the RoundUp or the "weeds" wouldn't die.  The RoundUp Ready plant absorbs the RoundUp too; it just doesn't die.  How much glyphosate and POEA persists in a single harvested seed?  Who knows?  I can't find a single study that's attempted to measure it, but then, I don't have access to a University Institutional subscription.  However, it doesn't take a PhD to hypothecate that, because of the nature of POEA, at least some small trace amount of highly toxic stuff makes its way into the seeds.

        If you're eating only a small number of the RoundUp infused seeds from, say, a few ears of corn over the course of a summer or a few soy nuts every now and then, then no big deal. But you're not.  Ninety-five percent of all the corn, soy, and canola grown in the US is RoundUP ready and has been sprayed at least one time in its life cycle with Roundup. You're getting small doses of the stuff in just about all the processed food you eat. Just go check your cupboard, pantry, fridge and freezer. Unless you eat a gluten-free, soy-free diet there's probably nothing in there that doesn't have corn products, soy products, or "mixed vegetable oils" in it.

        High fructose corn syrup, corn starch, modified food starch, corn oil, corn gluten, xanthan gum (a thickening agent and stabilizer found in a host of products as common as yogurt and salad dressing) and zein (used as a coating on confections) are all made from the 95% of harvested corn that has been sprayed with the stuff. Soybean oil and hydrolyzed or "texturized" soy protein are made from the 95% of harvested soy that has been sprayed with Roundup, as has all the tofu, miso, tempeh, soy sauce, bean curd, bean paste, soy milk, soy cheese, soy flour, soy nuts and edamame produced in the US that isn't labeled organic.  Same goes for your canola oil.  If it's not organic, it was sprayed with RoundUp.

        A trace amount of POEA may not do a lot of damage to your system, but think about what a steady diet of the stuff would do over the course of a lifespan, especially if you are consuming large amounts of high fructose corn syrup and vegetable oil.  Now add in the POEA that's made its way into the ground and surface water and will soon be coming out of your tap...if it isn't already.  Gives one pause, doesn't it?  Do you really want to eat that shit?  Do you really want to feed it to your kids?
