Kellogg’s Kashi Cereal Tests Positive for Probable Human Carcinogen and GMO

PLEASE NOTE: The box of Kashi GoLean Original we tested was NOT verified by the Non-GMO Project. While this product has been subsequently verified by the Non-GMO Project, there are still boxes which have not been verified on store shelves. In addition, we release the results of these tests because there are still other unverified products in the Kashi line that likely contain similar ingredients.

According to the Kashi website: “Progressive nutrition is our approach to food. It means we value whole food and put the inherent nutrition of food first when considering every ingredient. It means we make our food with a plants-first mindset. It means we value not just the foods we make, but how we make them by being mindful of sustainable and ethical farming practices.”

We sent a box of of Kashi GoLean Original cereal that was NOT verified by the Non-GMO Project to independent labs for testing to find out if Kashi is true to their word.


Glyphosate is the active chemical ingredient in Roundup herbicide as well as many other name brand glyphosate-based herbicides. These herbicides are the most widely used in the world and their use has increased exponentially with the introduction of GM crops. In response to agrichemical industry requests, the EPA has incrementally increased the allowable tolerance levels of glyphosate residues in crops since their introduction into our food supply.

A glyphosate residue test was conducted by an accredited lab using the Specific LC/MS/MS testing method with a minimum detectable level of 0.02 ppm. The test documented the presence of glyphosate in the box of Kashi GoLean Original which was not verified by the Non-GMO Project, at a level of 0.68 ppm, or 0.68 mg/kg. This level is nearly 6 times higher than the levels detected in the independent testing we commissioned on Froot Loops. The test also documented the presence of AMPA (aminomethylphosphonic acid), a metabolite of glyphosate, at an even higher level of 0.81ppm or 0.81mg/kg. This is the first time the lab has documented the presence of AMPA in the products we’ve had tested. The test results give significant reason for concern. There is a growing body of scientific evidence (4) that links glyphosate to health and environmental harm.

Dr. Jeff Ritterman states:

Monsanto’s Roundup, the trade name for the herbicide glyphosate, causes birth defects and cancer and probably triggers a host of chronic diseases. Allowing glyphosate to be present in our food should be a criminal offense. It is basically mass poisoning of the population including our children.

(Note: “Roundup” is Monsanto’s trademarked name for their glyphosate-based herbicide formulation. There are many other brands produced and sold by other companies around the world.)


Glyphosate, the carcinogen

In March, 2015, The International Agency for Research on Cancer (IARC), the specialized cancer agency of the World Health Organization (WHO), concluded that there is sufficient evidence of glyphosate’s carcinogenicity in experimental animals and classified glyphosate as probably carcinogenic to humans (1).

Glyphosate, the endocrine disruptor

An in-vitro study observed that glyphosate, at minute real-world environmental levels of exposure, was able to effectively substitute for estrogen in stimulating growth of hormone-dependent human breast cancer cells at concentrations starting at 10-12M (169 parts per quadrillion) and peaking at 10-9M (169 parts per trillion) (3). The growth stimulating effect of glyphosate (and the estrogen control) on the breast cancer cells decreased at concentrations higher than 169 ppt, demonstrating a “non-linear” or “non-monotonic” response, which is typical of chemicals that possess an endocrine (hormone) disruptive capability where minute levels can actually cause their own distinct problems.  

Studies suggest glyphosate based herbicides at realistic doses may be an endocrine disruptor (5) which may reduce testosterone levels (6,7), impair sperm quality (7), or could cause disturbances in the reproductive development of rats when the exposure was performed during puberty (8).

Glyphosate poses a risk to children prior to conception, throughout pregnancy and in early life

According to The President’s Cancer Panel:

It is vitally important to recognize that children are far more susceptible to damage from environmental carcinogens and endocrine-disrupting compounds than adults. To the extent possible, parents and child care providers should choose foods, house and garden products, play spaces, toys, medicines, and medical tests that will minimize children’s exposure to toxics. Ideally, both mothers and fathers should avoid exposure to endocrine-disrupting chemicals and known or suspected carcinogens prior to a child’s conception and throughout pregnancy and early life, when risk of damage is greatest (2).

Glyphosate linked to organ damage

Glyphosate based herbicides may also potentially damage the liver (7,9,10) and cause disturbances of intestine smooth muscle activity (11).

AMPA (aminomethyl-phosphonic acid) more toxic than glyphosate?

In an vitro study, AMPA was observed to be more toxic than glyphosate on human embryonic kidney and placental cells and the combination of glyphosate and AMPA was more toxic than glyphosate or AMPA alone (16).

Glyphosate and AMPA have been detected in air, rain, and water (12,13). AMPA is more persistent than glyphosate in the environment (14). Both glyphosate and AMPA have been detected in food (15) and glyphosate residues may remain on foods several months after spraying (14).


The quantitative PCR test documented, by DNA analysis, that approximately 55% of the soy in the box of Kashi Go Lean Original contained DNA sequences known to be present in Roundup Ready GMO soy. Approximately 7% of the corn was also GMO, containing DNA sequences known to be present in insecticide-producing Bt corn. Peer reviewed studies show cause for concern.

GMO soy and organ damage

Studies suggest animals fed Roundup Ready soy had potentially adverse cellular abnormalities or other disturbances in organs such as the pancreas (18,19,20), liver (21,22,23,24), kidneys (25) and adrenal glands (26). Some of these abnormalities were reversed when the animals were switched to non-GMO soy (27,28).

GMO soy linked to reproductive problems, including reduced fertility, lower birthweight and increased mortality

Animals fed Roundup Ready soy had disturbances in reproductive organs such as the ovaries (29,30) and testes (24,31). Studies have also observed reproductive issues in adult rodents fed Roundup Ready soy (32,33), lower birthweight and increased mortality of their offspring (34,35).  

GMO soy linked to other health risks

It has also been suggested that Roundup Ready soy consumption may reduce immune and endocrine function (36) and increase the risk of intestinal infections (37). A recent study observed that GM soy is not substantially equivalent to Non-GMO soy. Using 35 different nutritional and elemental variables to characterise each soy sample, the authors were able to discriminate GM, conventional and organic soybeans without exception, demonstrating “substantial non-equivalence” in compositional characteristics for ‘ready-to-market’ soybeans. GM soy also contained high residues of glyphosate and AMPA, whereas samples of conventional and organic soy tested contained none of these residues (15). Non-GMO soy has also been observed to have increased, potentially beneficial polyphenolic content and a higher number of sterols, and may be more anticarcinogenic against a colon cancer cell line compared to GM soy (17).

Corn that is a plant incorporated pesticide

The Bt corn in Kashi GoLean Original produces insecticides from inside every cell of the plant that can’t be washed off, and is regulated by the EPA. The FDA, EPA, and USDA allowed the insecticidal GMO corn discovered in Kashi GoLean Original to be commercialized without ever conducting human safety tests.

The scientific evidence that suggests Bt crops may have deleterious effects on health and the environment continues to increase (38)

An in-vitro study found that the insecticides in this corn may be toxic to human cells (39). Feeding studies conducted on mammals found adverse effects, including immune system disturbances (40), blood biochemistry disturbances (41), male reproductive organ damage (42), disturbances in the functioning of the digestive system (42), hyperlipidaemia and higher blood glucose levels (43) and signs of organ toxicity (44)(45)(42)(46). Industry claims that these insecticidal proteins are broken down in the digestive tract, yet a study found the proteins circulating in the blood of pregnant and non-pregnant women and the blood supply to fetuses (47). The research team conducting this study concluded, “Given the potential toxicity of these environmental pollutants and the fragility of the foetus, more studies are needed.” To date there has been no follow up study.


Profits from the Kashi brand go into Kellogg’s fight against our movement for food transparency and food justice. Kellogg’s has spent over $3.6 million to lobby against mandatory GMO labeling in 2013 and 2014. The corporation contributed $2 million to fund deceptive advertising to defeat citizens’ ballot initiatives for mandatory GMO labeling in CA, WA, OR and CO. Kellogg’s is also a member of the Grocery Manufacturers Association (GMA), an industry front group that is pushing for the passage of the DARK Act – a federal bill that would outlaw mandatory GMO labeling at the state and federal level. The DARK Act doesn’t stop there. It would overturn GMO crop cultivation bans passed at the county level such as those in Jackson and Josephine Counties, Oregon, and in many counties in Northern California. It would allow GMOs to be labeled “natural” and allow some GMOs to be labeled as non-GMO. And to further deceive the American People, it would likely do away with the independent nonprofit Non-GMO Project Verified label in favor of a corrupted USDA non-GMO label.

Kellogg’s markets their Kashi brand to health conscious consumers who are misled to believe that Kellogg’s sources healthier ingredients for all products in the Kashi line. Based on the results of the above tests, this is not the case. Additionally, the fact that both unverified and Non-GMO Project Verified boxes are being mixed together on store shelves points to an attempt to further deceive consumers.

While Kellogg’s has a number of products in the Kashi product line that are Non-GMO Project Verified (some of which are also organic), the company has made no attempt to make any changes to the products which it directly markets to growing, vulnerable children. This is not acceptable.


1. BOYCOTT all of Kellogg’s products and brands, including Kashi.

2. REPORT any unverified boxes of Kashi GoLean Original mixed with Non-GMO Project Verified boxes to your grocery store manager. Tell them that this is a deceptive practice and to immediately remove the unverified boxes.

3. DONATE to our food testing program, Operation: Label GMOs. We will continue testing processed foods to bring consumers the information they need to make informed food choices and provide the transparency they so deserve.
