Glyphosate (Monsanto’s Roundup) is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf weeds and grasses that are known to compete with commercial crops grown around the world. It has several advantages over many herbicides in that it breaks down in the soil into non-toxic organic molecules, reducing or eliminating contamination of groundwater and lower soils.
Monsanto has developed genetically modified (GMO) grains that are resistant to glyphosate, so that agriculture can apply the herbicide to kill the competitive weeds while not harming the crop. This allows farmers to suppress the weeds while allowing better production out of the grain crop.
Whatever the benefits of glyphosate, GMOs and the herbicide are tied together in many minds. And there has been an ongoing effort by many people to claim that glyphosate causes cancer. But let’s look at the science, because maybe we’ll get some information.
What’s this about cancer?
The famous (or is that infamous?) study from Séralini, which claimed that glyphosate and GMO corn caused cancer in rats, is quite popular with the anti-GMO forces. For many reasons, including bad statistics, improper experimental design, and bad conclusions, the article was retracted by the journal.
Because that article was retracted, it doesn’t actually count because it really doesn’t exist (but to be fair, it was eventually, re-published in a very low ranked journal). This story is frighteningly similar to the story of that cunning fraud, Mr. Andy Wakefield, who wrote a fraudulent, and ultimately retracted, article about vaccines and autism. I guess Séralini is the Wakefield of the GMO world.
There are better studies out there–maybe.
