Do Bob's Red Mill oats have glyphosate? A complete guide to understanding contamination risks

6 min read

In 2018, tests conducted by the Environmental Working Group (EWG) found detectable traces of the herbicide glyphosate in various oat products, including some from Bob's Red Mill. This revelation sparked widespread consumer questions about the purity and safety of their favorite oats. The answer to whether Bob's Red Mill oats contain glyphosate is complex, depending on whether you choose organic or conventional varieties, and understanding the potential for cross-contamination is key.

Quick Summary

Bob's Red Mill's organic oats are not treated with glyphosate, but trace amounts are possible due to environmental drift from other farms. Conventional oats, while not intentionally sprayed by BRM's direct farmers, carry a higher contamination risk through broader supply chains.

Key Points

  • Organic vs. Conventional: Bob's Red Mill's organic oats are grown without glyphosate, but trace amounts are possible due to environmental cross-contamination, whereas conventional varieties have a higher risk.

  • Past Contamination Evidence: The Environmental Working Group's (EWG) 2018 tests found varying levels of glyphosate in some Bob's Red Mill oat samples, both organic and conventional.

  • Third-Party Certification: The USDA Organic label prohibits intentional glyphosate use, but third-party 'Glyphosate Residue Free' certification offers a stricter guarantee with testing to ensure very low to non-detectable levels.

  • Company Testing: Bob's Red Mill relies on its suppliers to perform chemical testing and does not conduct random sampling for glyphosate itself, unlike its strict Purity Protocol for gluten testing.

  • Mitigating Exposure: To minimize exposure, consumers should choose certified organic oats and consider brands with specific glyphosate-free certifications if possible.

Understanding the Glyphosate Concern in Oat Products

Glyphosate is the active ingredient in the weedkiller Roundup and is widely used on conventional crops. While oats are not a genetically engineered crop, glyphosate is often used as a pre-harvest desiccant. This practice, common in conventional agriculture, helps dry out crops to speed up harvesting. This widespread use means glyphosate can turn up in food products, raising health concerns among some consumers, though federal agencies like the EPA have established tolerance limits.

For conscientious consumers, the presence of any amount of glyphosate is a concern, and this has led many to seek out brands that prioritize purity. Bob's Red Mill, a brand often associated with natural and wholesome products, has faced scrutiny following reports that its oats contained trace amounts of the herbicide.

Bob's Red Mill's Official Stance and Sourcing Practices

Bob's Red Mill addresses the issue of glyphosate directly on its website, providing transparency into its sourcing practices. The company states that it has agreements in place with its oat suppliers, covering both its organic and conventional products, specifying that oats should not be treated with glyphosate.

  • Organic Oats: For products bearing the USDA Organic seal, the National Organic Program (NOP) prohibits the use of synthetic herbicides like glyphosate at any point during cultivation. The company sources from farmers committed to these standards. However, Bob's Red Mill acknowledges that trace amounts can be present in organic crops due to environmental factors, such as wind drift from nearby conventional fields.
  • Conventional Oats: The company has historically stated that most of its conventional oats come from regions with longer growing seasons where desiccation is less common. While it requires suppliers to avoid glyphosate, the larger, multi-source nature of the conventional supply chain makes it difficult for them to guarantee no use by all farmers.

Bob's Red Mill's Testing Protocols

It is important to note that Bob's Red Mill relies on its suppliers to perform chemical testing and does not conduct random sampling itself, though its products must meet all USDA and FDA maximum tolerance levels. The company's in-house testing protocols, particularly its strict "Purity Protocol" for gluten-free products, focus primarily on preventing cross-contamination with gluten-containing grains, not on testing for pesticides like glyphosate.

Evidence from Independent Testing

Despite Bob's Red Mill's stated policies, independent tests have revealed inconsistencies. The 2018 EWG report, which tested various oat-based foods, found that samples of Bob's Red Mill Steel Cut Oats contained 300 ppb (parts per billion) of glyphosate, while Bob's Red Mill Organic Old Fashioned Rolled Oats showed lower levels, with some organic samples having non-detectable levels and others at 10 or 20 ppb.

The lawsuits that followed the EWG report, though not based on a violation of federal safety limits, argued that marketing products as natural was misleading when they contained any level of a synthetic chemical. This highlights a key divide between what is legally permissible and what consumers perceive as pure and natural.

The Difference Between Organic and Conventional Oats

For consumers concerned about glyphosate, the choice between organic and conventional is critical. The following table summarizes the key differences in how Bob's Red Mill's organic and conventional oat products are affected by glyphosate.

Feature Bob's Red Mill Organic Oats Bob's Red Mill Conventional Oats
Glyphosate Use Policy Prohibited from intentional use during growing and processing, per USDA Organic standards. Suppliers agree not to use glyphosate as a desiccant, but large supply chains make a full guarantee difficult.
Risk of Contamination Low, but possible for trace amounts due to environmental drift from nearby conventional fields. Higher risk of contamination due to conventional farming practices within the broader supply chain.
Independent Test Results (EWG 2018) Found lower, trace amounts (0–20 ppb) in some samples. Found higher levels (300 ppb) in some samples.
Testing Practice Relies on supplier testing to meet federal limits; not randomly sampled for glyphosate by BRM. Relies on supplier testing to meet federal limits; not randomly sampled for glyphosate by BRM.

How to Minimize Your Exposure to Glyphosate

For those wanting to reduce or eliminate glyphosate exposure, several steps can be taken when choosing and preparing your oats:

  • Prioritize Certified Organic: As organic farming prohibits the use of glyphosate, certified organic oats are the most reliable option for reducing exposure. While drift contamination is a slight possibility, organic products consistently show significantly lower levels compared to conventional alternatives.
  • Look for 'Glyphosate Residue Free' Certification: For the highest assurance, seek products that carry a third-party certification specifically for glyphosate residue. Brands with this certification, such as Back Roads or Almond Cow, test their finished products to ensure residues are below a strict threshold.
  • Choose Carefully at the Store: While Bob's Red Mill organic oats are a good option, if you have concerns about residual levels, researching brands with more stringent testing or sourcing protocols is recommended. Consider brands that explicitly state they are certified glyphosate residue free.
  • Wash Grains (with caution): According to some sources, rinsing grains with a baking soda solution may help remove some surface pesticide residue, but this will not remove chemicals that have been absorbed into the plant.

Conclusion

In summary, while Bob's Red Mill prohibits the intentional use of glyphosate on its oats, the answer to whether their products are completely free of the chemical is not a simple yes or no. The presence of trace amounts has been independently verified in past tests, even in organic versions, due to cross-contamination from the environment. Conventional oats from broader supply chains face a higher risk. For consumers, choosing certified organic oats is the most effective way to minimize potential exposure. However, for those seeking the highest assurance of purity, opting for brands with an independent 'Glyphosate Residue Free' certification is the recommended approach. For more information, see Bob's Red Mill's article on glyphosate. Ultimately, consumer preference for purity beyond legal tolerance levels drives the demand for greater transparency from all food manufacturers.

Frequently Asked Questions

No. While Bob's Red Mill states it works with suppliers to avoid glyphosate use, past independent testing has found trace amounts in both conventional and organic products, largely attributed to environmental cross-contamination.

The presence of glyphosate in organic products, which are not intentionally sprayed, is most likely due to herbicide drift. Chemicals can be carried by the wind from nearby conventional farms and contaminate organic crops.

Trace levels of glyphosate found in oat products typically fall below the EPA's federal tolerance limits, which are considered safe for consumption. However, consumer comfort with these levels varies, and some prefer a zero-tolerance approach.

The USDA Organic standard prohibits the intentional use of glyphosate during farming, but it doesn't test for it in finished products. A 'Glyphosate Residue Free' certification, often from a third party like the Detox Project, requires final product testing to ensure chemical residue is below a strict limit.

For the highest certainty, look for oat products certified 'Glyphosate Residue Free' by an independent third party, such as the Detox Project. Some brands like Back Roads and Almond Cow have this certification.

The 'Non-GMO' label does not guarantee a product is free of glyphosate. All oats are considered non-GMO, but conventional oats can still be sprayed with glyphosate as a desiccant before harvest.

Yes, in 2018, class-action lawsuits were filed against Bob's Red Mill alleging that advertising their products as wholesome was misleading, given the presence of glyphosate. The suits claimed the marketing failed to disclose this information to consumers.
