What is Glyphosate and Why the Concern?
Glyphosate is a broad-spectrum herbicide and the active ingredient in many weed killers, including Roundup. It is widely used in conventional agriculture to manage weeds and, controversially, as a pre-harvest desiccant on crops like oats, wheat, and legumes to speed up ripening.
Public health concerns about glyphosate have been raised by several organizations. The World Health Organization's International Agency for Research on Cancer (IARC) classified glyphosate as "probably carcinogenic to humans," a classification debated by other regulatory bodies like the U.S. Environmental Protection Agency (EPA). Despite conflicting views on safety levels, research has linked chronic, low-level exposure to potential health issues, including neurological effects and gut microbiome disruption. These concerns motivate many consumers to actively seek out foods free from this chemical.
Identifying Products with Third-Party Certifications
Fortunately, for consumers who want certainty, specialized third-party certifications offer the most direct way to know if a product is glyphosate free. These certifications involve rigorous, independent laboratory testing of finished products to ensure no detectable glyphosate residue.
- The Detox Project's Glyphosate Residue Free Certification: Established in 2018, this program verifies that food products do not contain glyphosate residues down to low limits of detection (LODs). Look for the distinctive green and black circular logo on product packaging. Brands like Chosen Foods, Ithaca Hummus, and many others carry this label.
- BioChecked's Non-Glyphosate Certified: Another independent certification, BioChecked, tests products to ensure they contain less than 0.1% glyphosate. It provides another reliable indicator for consumers focused on avoiding this specific herbicide.
When you see one of these seals on a product, you can be confident it has undergone specific testing for glyphosate residue.
The Limitations of Other Labels
Many people incorrectly assume that certain other labels guarantee a product is glyphosate free. While they are a step in the right direction, it's vital to understand their limitations.
- Certified Organic: A product with the USDA Certified Organic seal is grown without the intentional application of synthetic herbicides like glyphosate. However, this does not guarantee zero glyphosate residues. Contamination can occur through environmental factors such as wind drift from neighboring conventional farms or contaminated water. While residue levels are typically much lower than in conventional food, they are not necessarily non-existent. The Detox Project's certification, for instance, specifically tests the final product, which provides an extra layer of assurance that organic alone does not offer.
- Non-GMO Project Verified: The Non-GMO Project Verified seal ensures a product does not contain genetically modified ingredients. While many crops are genetically engineered to withstand glyphosate spraying, the label doesn't address the use of this chemical on non-GMO crops. In fact, many non-GMO crops like oats and pulses are desiccated with glyphosate just before harvest, making them a significant source of residue. Therefore, this seal is not an indicator of a product's glyphosate status.
A Comparison of Food Labels and Certifications
| Certification/Label | Glyphosate Use Banned? | Final Product Tested? | Protection from Drift Contamination? |
|---|---|---|---|
| Glyphosate Residue Free | Yes (Indirectly) | Yes | Yes (Tested below LOD) |
| Certified Organic | Yes | No (Generally) | No (Vulnerable to drift) |
| Non-GMO Project Verified | No (No guarantee) | No | No |
Practical Steps for a Glyphosate-Free Diet
Making educated choices in the grocery store is the most effective way to avoid glyphosate. Here are some actionable tips:
- Prioritize High-Risk Foods for Certified-Organic or Glyphosate-Free Labels: Some crops are more susceptible to pre-harvest desiccation with glyphosate. Pay special attention to these items when shopping: grains like oats, wheat, and barley; legumes such as beans, lentils, and chickpeas; and seeds like flax and sunflower.
- Choose Whole, Unprocessed Foods: The more a food is processed, the higher the chance of it containing ingredients from various sources, potentially increasing the risk of contamination. Opting for whole foods and preparing meals at home gives you more control.
- Review Lists of Certified Products: Organizations like The Detox Project maintain online databases of certified products and brands. You can browse these lists to find verified products.
- Consider Local Farmers: Getting to know your local farmers is a great way to understand their farming practices and can provide additional assurance about the safety of your food. Many local growers use sustainable methods that avoid synthetic chemicals.
- Filter Your Water: Glyphosate is water-soluble, and studies have detected its presence in tap water, especially in agricultural areas. Using a high-quality water filter, such as a reverse osmosis system, can help remove contaminants.
Conclusion
Understanding how to know if a product is glyphosate free involves more than just relying on generic health claims. While labels like 'organic' and 'non-GMO' are beneficial, they do not provide the same level of assurance as specific certifications like the Glyphosate Residue Free seal from The Detox Project or BioChecked's Non-Glyphosate Certified program. By prioritizing third-party certifications, focusing on high-risk foods, and cooking with whole ingredients, consumers can make confident decisions to minimize their exposure to this common herbicide.
