Suppressed Report Shows Cancer Link to GM Potatoes

Doc Ruby writes "After an 8-year-long court battle, Welsh activists have finally been allowed to released a Russian study showing an increased cancer risk linked to eating genetically modified potatoes. While the victory of the Welsh Greenpeace members in the courtroom would seem to vindicate the work of the Russian scientists that did the original research, there are still serious questions to be answered. The trials involved rats being fed several types of potatoes as feed. The rats who were fed GM potatoes suffered much more extensive damage to their organs than with any other type; just the same, serious questions remain about the validity of the findings. The Welsh group wants to use this information to stop the testing of GM crops in the UK, tests currently slated for the spring of this year."

    There's two sides to the terminator gene, as I understand it, one of which you're overlooking. Suppose you engineer a crop which grows extremely well, much better than in its original form. This crop might spread wildly, and become a form of a weed, overcoming native plants and even other useful crops. The terminator gene is useful here because it prevents the crop from spreading into the wild. In this way it's a safeguard.

    Suppose there is some series of studies confirming that a particular crop is statistically more correlated with the occurrence of some medical problem in humans who eat it. If that crop has already spread in the wild, and perhaps merged with non GM crops, then we'll still be eating it whether we like it or not. We need safeguards like the terminator gene.

    A few juicy points from the book (not in the order as they appear in the book, just the order it came out from my memory), though I knows too little to judge if their validity:
    • In the book it mentioned one similar experiment with potatoes and mice (not sure if this is the same one), however, the experiment is so poorly controlled (e.g. the GM potato contains less vital nutrients compared to the "normal" potatoes) that the mice are more likely damaged through malnutrition than any effect of GM food. Other experiments that accounts for all the intake value of different nutrients showed no harmful effects for GM food.
    • Agriculture in its current form (with pesticides, fertilizers, etc) is already the most destruction thing human does routinely to nature. Any additional "damage" to the environment due to planting GM crops won't make much a difference anyway.
    • Corn farmers already have to buy seed every year from dealers, no terminator gene needed! Why? Because modern corn are usually hybrid breeds that give great yield but do not generate viable seeds. But you don't see NGOs screaming at seed dealers. This shows that farmer don't mind buying seed constantly as long as the yield difference is worth the price.
    • People has been making genetically new variants of plants for centuries already (i.e. through selective breeding). Needless to say, none of these new variants are subjected to as much scrutiny as GM foods has gone through (yet some still think them "unsafe").
    • Before GM, there were already other means (e.g. soaking in chemicals, radiation, etc) to cause genetic mutation in plants, which can also result in new variants of plants. These crops, however, are not called "GM" and can be sold with as much testing as variants obtained through breeding (i.e. no testing at all).
    • In some cases, the use of GM crops can and do reduce the use of pesticides, so it is not all bad.
    • Furthermore, one of the famous GM linked pesticide (Roundup), has the advantage of naturally decaying in matter of weeks. Thus using Roundup linked crop with Roundup do leave less harmful chemicals around in the environment.
