Understanding the Presence of Glyphosate in Milk
Glyphosate is one of the most widely used herbicides in global agriculture, applied to conventional crops to control weeds. For milk, the potential for glyphosate residue depends on the food source for the dairy animal or the crop used for plant-based alternatives.
For dairy milk, conventional cattle are often fed genetically engineered grains, such as corn and soy, which are designed to withstand direct glyphosate application. While trace amounts can end up in feed, multiple studies have shown only negligible levels of glyphosate excreted in cow's milk, which is often below the limit of detection in product tests. However, organically raised dairy cattle are fed certified organic feed, which prohibits the use of synthetic herbicides like glyphosate. This significantly lowers, but does not completely eliminate, the risk of contamination, as drift from nearby conventional farms is always a possibility.
For plant-based milks, the risk of glyphosate presence is tied directly to the crop used. Oat milk, for example, has garnered attention due to the common practice of applying glyphosate as a desiccant, which dries crops before harvest. Independent testing has confirmed detectable levels of glyphosate in some conventional oat products, although a 2023 report found many oat milk brands had non-detectable levels. Almond milk, sourced from almonds that are often heavily treated with pesticides, is also a concern. However, the edible almond kernel is largely protected by the hull and shell, potentially reducing the risk of contamination. Nonetheless, choosing certified organic almonds is the safest option. Soy milk also presents a risk, as most conventional soy is genetically modified to be glyphosate-resistant.
Your Checklist for Finding Glyphosate-Free Milk
To confidently choose a milk free of glyphosate residue, follow these steps:
- Prioritize Third-Party Certification: Look for a 'Glyphosate Residue Free' certification from an independent organization like The Detox Project. This label confirms that the final product has been tested by a third-party lab and contains no detectable residue. Many brands display this on their packaging or website.
- Choose Certified Organic: This is the next best option. While not a guarantee against all contamination, the USDA Organic seal means the ingredients were grown without synthetic pesticides like glyphosate. Organic milks have a far lower risk of containing residues than conventional products.
- Check the Ingredients: For plant-based milks like oat, almond, or soy, make sure the ingredients list explicitly states "organic." This is especially important for oat milk, where non-organic oats are known to carry a higher risk of containing glyphosate.
- Consider Homemade: The most effective way to ensure your milk is glyphosate-free is to make it yourself. By purchasing certified organic oats or almonds, you can control the entire process from start to finish. Some brands like Almond Cow sell bulk ingredients certified glyphosate-free specifically for this purpose.
Comparison of Milk Types and Glyphosate Risk
| Milk Type | Likelihood of Glyphosate Presence | Key Factor | Recommended Action |
|---|---|---|---|
| Conventional Dairy | Low, but possible | Glyphosate is mostly excreted by cattle, so residues are typically negligible or not detected. | Look for the "USDA Organic" seal or third-party certification for certainty. |
| Organic Dairy | Very Low | Fed organic feed, which prohibits glyphosate. Minimal risk from environmental drift. | A safe choice for most consumers. |
| Conventional Oat Milk | Highest risk among plant-based options | Glyphosate is used as a drying agent on conventional oats before harvest. | Avoid unless certified organic or "Glyphosate Residue Free." |
| Organic Oat Milk | Low risk, but possible | Uses organic oats, minimizing direct exposure. Still susceptible to environmental drift. | Look for The Detox Project certification for extra assurance. |
| Conventional Almond Milk | Moderate risk | Almond crops are heavily treated with pesticides, including glyphosate, although the kernel is somewhat protected. | Choose certified organic to minimize risk. |
| Organic Almond Milk | Low risk | Uses organic almonds, grown without synthetic pesticides. | A safe choice for almond milk consumers. |
| Organic Coconut Milk | Low risk | Coconuts are less susceptible to residue from soil-based contaminants. | A low-risk option. |
Certified Glyphosate-Free Brands
Several brands have taken the extra step to obtain third-party verification to ensure their products are free of glyphosate residues. The Detox Project's certified products list is a great resource. Brands that have appeared on lists of tested products with non-detectable levels or are specifically certified include:
- Oatly: The low-fat version has been certified Glyphosate Residue Free by The Detox Project.
- Califia Farms: Their Organic Original Oat Milk is certified Glyphosate Residue Free.
- Kirkland Signature: Their Organic Oat Non-Dairy Beverage is certified Glyphosate Residue Free.
- Willa's: Their oat milks use organic oats and are certified Glyphosate Residue Free.
- Minor Figures: Their Organic Oat Milk is certified Glyphosate-Free by The Detox Project.
- MALK Organics: Certifies their products as glyphosate-free, and testing found their oat milk with no detectable glyphosate in a 2023 report, contrary to some initial confusion.
- Three Trees: Mentioned in several tests as being free of detectable glyphosate.
- Planet Oat: Also listed in studies as having no detectable glyphosate.
Conclusion: Making Your Safest Choice
For consumers, the most assured way to find milk free of glyphosate is to look for products certified by an independent, third-party organization like The Detox Project. The next safest bet is opting for USDA Certified Organic dairy or plant-based milks, although the possibility of environmental drift means the residue risk is not zero, but still significantly lower than conventional options. For those with the time and interest, making homemade milk from certified organic and glyphosate-free ingredients is the ultimate way to control your intake. Ultimately, being a proactive shopper who understands labeling and certifications is the key to making informed, healthier choices for your family.

Can organic milk still contain glyphosate?
Yes, but it is extremely unlikely. Organic farming prohibits the use of glyphosate, but environmental factors like drift from nearby conventional farms can cause cross-contamination. Independent certification provides greater assurance.
How does glyphosate get into milk?
For dairy milk, cows are fed crops like corn and soy that may have been treated with glyphosate. For plant-based milk, the crop used (e.g., oats, almonds) can retain residue from herbicide applications.
Is the level of glyphosate in milk dangerous?
Official health authorities often state that detected levels are within legal limits and pose no immediate food safety concern. However, some groups express concern over long-term exposure and potential health effects, leading to consumer interest in avoidance.
Is all oat milk at risk for glyphosate contamination?
No. Only conventional oat milk carries a higher risk due to pre-harvest spraying practices. Many organic and certified brands have non-detectable levels.
Are any other plant-based milks affected?
Soy milk from non-organic soybeans is at risk, as most are genetically modified to tolerate glyphosate. Conventional almond milk may also have residue, but the edible nut is somewhat protected during growth.
What is The Detox Project certification?
It is an independent third-party certification that tests food products for glyphosate and heavy metal residues. Products certified as 'Glyphosate Residue Free' have no detectable residue based on the lab's testing limits.
How can I make my own glyphosate-free milk?
Buy certified organic and Glyphosate Residue Free ingredients, such as oats or almonds, and use a home milk maker or blender to create your own fresh milk.
