Bayer has suffered a defeat in the US litigation surrounding the chemical PCB, which has been banned for decades.
A jury jury awarded three teachers a total of 185 million dollars in damages on Wednesday night in Seattle, Washington, who hold the environmental toxin PCB responsible for brain damage.
As with other legal cases, the competent judge could still reduce the amount.
Should it become necessary, the company, which does not share the jury's assessment, will consider appealing.
Like the billions in legal disputes over alleged cancer risks of the weed killer glyphosate, the PCB processes are an expensive legacy of the US seed company Monsanto, which Bayer took over in 2018.
Another major construction site
In addition to the glyphosate lawsuits, PCB is another major legal construction site of the Leverkusen-based company.
Bayer is currently working on an agreement with plaintiffs in the federal district court in Los Angeles.
Only in May, the judge again rejected an agreement reached in June of last year on the grounds of allegedly contaminated waters with the chemical PCB.
The judge complained, among other things, of the deadline for filing claims, but also said that a solution was being approached.
In the PCB proceedings, Monsanto is accused of hiding the devastating consequences of the toxic pollutants for nature and living beings for decades. The company was the only manufacturer of polychlorinated biphenyls (PCB) in the USA from 1935 to 1977. In 1979 the chemical was banned there. In Germany, PCBs have not been allowed to be used since the late 1980s.
