A Timeline of Monsanto’s Roundup Controversy

Class ActionConsumerPersonal Injury

Monsanto is no stranger to controversy. This is the company that brought us Agent Orange, an herbicide deployed during the Vietnam War that wound up traumatizing both the Vietnamese and our own troops. (Monsanto would later reach a $180 million settlement with Vietnam vets over diseases like leukemia, Hodgkin’s disease, non-Hodgkin’s lymphoma, Parkinson’s disease, and respiratory cancer.)

Hold Monsanto Accountable

In 1974, four years after the U.S. stopped using Agent Orange, Monsanto introduced Roundup (glyphosate)—another powerful herbicide that quickly became a mainstay on most American farms.

But like Agent Orange, Roundup would be linked to cancer. This herbicide, too, could wind up costing the company millions due to lawsuits.



Monsanto patents and releases Roundup-Ready seeds, which are genetically modified to withstand the ubiquitous Roundup herbicide. (These seeds/crops are known as GMCs: genetically modified crops.) This allows farmers to kill weeds (in the short term, at least) without also dooming their own crops.

Over the next 20 years, Roundup-Ready crops will come to dominate their respective markets, eventually reaching a 90% share.

Thanks to the Roundup-Ready patent and relevant legal protections—and Monsanto’s aggressive acquisitions of its competitors—some argue that Monsanto has a monopoly on the biotech industry. (Without question, it is the largest biotech company in the world.)


The Oscar-nominated documentary Food, Inc. is released on June 12. The film shows Monsanto in a harsh light, portraying the company as mobilizing an army of attorneys to bully farmers into using their Roundup-Ready soybeans—and suing those who won’t cooperate.

Importantly, the film emphasizes that the Roundup-Ready seeds are “terminating” seeds. That means farmers can’t replant them; instead, they must go back to Monsanto to buy more seeds whenever they run out.

Food, Inc. inflicts so much damage on Monsanto’s reputation that the company creates several pages on its website just to respond to the charges lobbed in the film.


Entropy—a peer-reviewed scientific journal based in Switzerland—publishes a study that concludes

glyphosate enhances the damaging effects of other food borne chemical residues and environmental toxins. Negative impact on the body is insidious and manifests slowly over time as inflammation damages cellular systems throughout the body.

According to the study, one of the consequences of this negative impact is cancer.

Hold Monsanto Accountable


In March, the International Agency for Research on Cancer, or IARC (part of the World Health Organization, or WHO) assesses the potential cancer-causing (carcinogenic) effects of glyphosate (Roundup). It determines that glyphosate is “probably carcinogenic to humans.”

That fall, plaintiffs file the first of at least 25 lawsuits against Monsanto over Roundup’s allegedly cancer-causing effects. Many plaintiffs, like Yolanda Mendoza, just sprayed Roundup on their yard every week.

Ms. Mendoza, a mother of three, contracted Non-Hodgkin’s Lymphoma in 2013. (After intensive chemotherapy, her cancer is currently in remission.)

“What everyone has in common is that they all used Roundup and they all have non-Hodgkin’s lymphoma.”

Her attorney Robin L. Greenwald tells CBS News, “Some people are landscapers, some people are migrant farm workers, some people are farmers. What everyone has in common is that they all used Roundup and they all have non-Hodgkin’s lymphoma.”

For the year, Monsanto rakes in $4.75 billion in herbicide sales.


In April, the Journal of Occupational and Environmental Medicine (JOME) publishes a study that concludes that herbicides like glyphosate are “associated with a high risk of cutaneous melanoma” (skin cancer), “in particular among those exposed to occupational sun exposure.”

In September, pharmaceutical giant Bayer AG announces it will buy Monsanto for $66 billion, raising serious concerns about rising prices for farmers. (This is the second massive merger of the year after the Dow-DuPont deal.)

Later that month, the U.S. Food and Drug Administration (FDA) finds trace amounts of Roundup in various oatmeals, cereals, and baby foods.

The next month, federal judges consolidate 21 Monsanto Roundup lawsuits into a multi-district litigation (MDL) in the Northern District of California.
