A new study, soon to be published in the June issue of Food Technology shows that extremely high levels of glyphosate—the active weed-killing chemical in Roundup is turning up in all kinds of food humans and farm animals eat every day. According to the study, soy laced with Roundup is ending up in thousands of non-organic packaged foods and in animal feed that livestock eat – so if you eat a lot of packaged foods and meat, you’re getting a bigger dose of Roundup per each meal. Part of the reason Roundup is showing up in so much of the food supply is because weeds become resistant to glyphosate, leading farmers to spray heavier glyphosate applications on their crops. During the new study, researchers looked at (genetically engineered) GE soy, conventional (but not GE) soy, and organic soy. ALL the GE soy contained glyphosate residue. The organic soy and conventional, non-GE soy didn’t contain glypshosate residues and also showcased a more beneficial nutritional profile compared to GE soy.
The researchers point out that the utter lack of data on pesticide residues in major crops is a serious knowledge gap that could have some major potential consequences for human health. That in mind, the researchers suggest, “increased effort on sampling and testing crop material from the market; testing for possible dose–response effects of chemical residues in long-term feeding studies; inclusion of pesticide residue measurements and safety testing in the regulatory system for risk-assessment and further research on the indirect ecological effects of herbicides and pesticides.” Although the United States has zero mandatory GMO labeling in place, Rodale points out that we should because, “There’s mounting evidence linking glyphosate to infertility, Parkinson’s disease, certain cancer, and birth defects.” If you’re looking to avoid GE ingredients in your food, eat more whole, organic foods and check out our GMO-free shopping guide.
