Shocking Test Results of Glyphosate in Breakfast Cereals
Moms Across America tested popular conventional and organic breakfast cereals for glyphosate — and the results shocked even our own researchers.
Key Findings
Laboratory analysis revealed glyphosate contamination across both conventional and organic cereal brands.
Conventional Cereals Positive for Glyphosate
9 out of 10 popular conventional breakfast cereals tested positive for glyphosate herbicide residue.
Organic Cereals Also Positive
6 out of 7 organic cereals tested positive for glyphosate — raising serious questions about the integrity of organic certification.
Kashi — Highest Level Detected
Kashi (which markets itself as healthy and natural) had the highest glyphosate reading of any cereal tested, at 23.53 parts per billion.
Results at a Glance
Conventional Cereal Results
| Brand | Glyphosate Level |
|---|---|
| Kashi | 23.53 ppb |
| Raisin Bran (Kellogg's) | 18.74 ppb |
| Frosted Flakes (Kellogg's) | 7.68 ppb |
| Cheerios (General Mills) | 1.67 ppb |
| Corn Flakes (Kellogg's) | 1.47 ppb |

| Trix (General Mills) | 0.19 ppb |
| Honey Smacks (Kellogg's) | Not detected |
Organic Cereal Results
Even cereals labeled “organic” were not immune to glyphosate contamination. 6 out of 7 organic cereals tested positive. This points to widespread environmental contamination and potential cross-contamination in supply chains.
| Brand | Glyphosate Level |
|---|---|
| Kashi Organic (soft baked cereal bar) | 23.53 ppb |
| Cascadian Farm Organic | 0.76 ppb |
| Nature's Path Organic | 0.65 ppb |
| Barbara's Organic | 0.41 ppb |
| Whole Foods 365 Organic | 0.37 ppb |
| Annie's Organic | 0.14 ppb |
| Earthbound Farm Organic | Not detected |
Why This Matters
Breakfast cereals are one of the most commonly consumed foods among American children. Glyphosate, the active ingredient in Roundup, is classified as a “probable carcinogen” by the International Agency for Research on Cancer (IARC).
Glyphosate is routinely sprayed on oat crops as a pre-harvest desiccant — meaning it is applied directly to grain shortly before harvest to speed drying. This practice results in high residue levels in the final product.
The finding that organic cereals also contain glyphosate residues is deeply concerning. Parents who pay a premium for organic products to protect their children deserve honest labeling and robust enforcement of organic standards.
Take Action
Demand transparency from cereal manufacturers and support stronger food safety regulations.
