On July 7, opening statements began in a state court in San Francisco in the first trial that tests whether Monsanto's Roundup herbicide, whose active ingredient is glyphosate, caused an individual to get cancer. In the case, Dewayne "Lee" Johnson, a former groundskeeper diagnosed four years ago with nonHodgkin's leukemia, is claiming that his exposure to glyphosate was the cause of his terminal illness. Monsanto faces about 4,000 cases in all over Roundup. In 2015, the International Agency for Research on Cancer classified glyphosate as a possible carcinogen, but other regulatory agencies have found no connection – indeed, in December 2017, the US EPA concluded that glyphosate is not likely to cause cancer in humans. "More than 800 scientific studies, the U.S. EPA, the National Institutes of Health and regulators around the world have concluded that glyphosate is safe for use and does not cause cancer," said Scott Partridge, vice president of global strategy at Monsanto, in a statement. "We have empathy for anyone suffering from cancer, but the scientific evidence clearly shows that glyphosate was not the cause. We look forward to presenting this evidence to the court."
