Bayer says more Americans are alleging Monsanto weedkillers cause cancer

Bayer said the number of American plaintiffs alleging its recently acquired weedkillers cause cancer has risen sharply, adding to concerns about potentially lengthy and costly litigation stemming from its acquisition of Monsanto. The German chemicals company on Wednesday also lowered its full-year earnings outlook because of delays in closing its $63 billion purchase of Monsanto, which included a portfolio of herbicides that contain glyphosate, notably flagship product Roundup.Bayer said it faced some 8,700 plaintiffs across the U.S. as of late August—mainly cancer patients who claim to have fallen ill after being exposed to the glyphosate-containing Monsanto herbicides. As of late July, the number of plaintiffs stood at about 8,000, up from 5,200 a few months earlier.
