There is a claim out there (way out there) that the weed killer glyphosate is present in food at unsafe levels. This claim appears in a work promoted by the likes of Food Democracy Now and Food Babe, not in peer reviewed journals. Still, in this forum, we place a premium on what is said, not who said it, so let’s examine the assertions.
The publication endorsed by the aforementioned pair alleges that that studies have uncovered dangerous amounts of the herbicide glyphosate in our cabbage and Oreos, among many other edibles. The cover of this work shows a foreboding figure in a hazmat suit saturating future food with what is implied to be toxic levels of chemicals. Accompanying that image is a munching baby next to a spray bottle of Roundup, a Monsanto product which contains glyphosate.
If shouts of alarm ever accompany a scientific study, they should come from those hearing the results, not those giving them. When the latter happens, it is almost always a sign that the “research” was meant only to confirm a desired outcome and that the Scientific Method was skirted. Still, let’s look at what the report said, not its cover or who produced it, in order to make a critical analysis of it.
Michelle Miller of Ag Daily notes that the methods used in the studies make it impossible to distinguish glyphosate from similar chemical structures and may not even be able to differentiate it from water. She wrote, “To detect glyphosate…costs hundreds of thousands of dollars and is a very difficult, scientifically complex task.” The methods cited in these studies fail to meet those standards, though not as spectacularly as Zen Honeycutt’s $125 device meant to detect glyphosate levels.
Another crucial point is how little glyphosate is spread over large farming areas. It’s just 22 ounces per acre, which would be equal to about two sodas sprinkled on a baseball diamond. Moreover, Miller reports that she sprays just two days a year and that’s done early in the growing season, before the edible part of the plant has emerged. Pointing out that the dose makes the poison, Miller adds that glyphosate is less toxic than baking soda.
Besides, the weed killer impacts enzymes found in plants and does not affect mammals, including humans. The only harm done to animals is when lab rats, mice, and fish are force fed outrageous amounts of it.
I’m all for studies as long as they follow established protocols, employ the Scientific Method, are replicable, and are peer reviewed. Along those lines, the Government Accountability Office once called on the FDA to monitor food for glyphosate residue. But the effort was halted due to a lack of agreement on testing protocols, equipment shortcomings, and the varying analysis methods at the different FDA laboratories.
Sensing a connection between the shuttered testing program and the experiments on overdosed rodents, Food Babe pounced: “Could it be that Monsanto didn’t like the results they started getting, especially since the FDA found glyphosate in foods that should be especially safe like BABY FOOD?”
Shouting something doesn’t make it more relevant and all caps won’t make it more accurate. Instead of providing evidence for the conspiracy she suggested, Food Babe let her followers assume it was true. She provided no examples of test results that Monsanto wouldn’t like, offered no audio recordings about keeping the findings hush-hush, and presented no independent lab experiments that revealed dangerous amounts of herbicide on our plates.
Another vacuous Food Babe claim is that multiple studies show that while probable harm to humans from glyphosate begins at one part per 10 billion, foods in the studies were found to have 1,000 times that. In truth, only one of the studies she listed provided support for that claim, and that one involved testing on mice. And even among vermin, the danger was considered potential instead of probable. Glyphosate, if it’s detectable on any food at all, is in nowhere close to a dangerous amount.
There are legitimate dietary concerns out there, but glyphosate residue is not among them. Alarmist, untrue charges, on the other hand, are much harder to stomach.
