In March 2015, the International Agency for Research on Cancer (IARC) reported that glyphosate, the main herbicide in Roundup, was “probably carcinogenic to humans.” Later, on July 7, 2017, the California state Office of Environmental Health Hazard Assessment (OEHHA) named glyphosate as a chemical that can cause cancer and added it to the state’s list of dangerous substances. This requires Roundup manufacturer Monsanto to add new warnings to the product label for sales in the state of California, but they have taken the issue to court, claiming that the change is unwarranted.

Meanwhile, hundreds of people have filed Roundup lawsuits against the company, claiming that after long-term exposure to the herbicide, they developed cancer and other serious injuries. Now, documents uncovered in discovery suggest that Monsanto may have manipulated evidence concerning glyphosate and its risks to human health.
