"Personal injury law firms around the United States are lining up plaintiffs for what they say could be "mass tort" actions against agrichemical giant Monsanto Co that claim the company's Roundup herbicide has caused cancer in farm workers and others exposed to the chemical.

The latest lawsuit was filed Wednesday in Delaware Superior Court by three law firms representing three plaintiffs.

The lawsuit is similar to others filed last month in New York and California accusing Monsanto of long knowing that the main ingredient in Roundup, glyphosate, was hazardous to human health. Monsanto "led a prolonged campaign of misinformation to convince government agencies, farmers and the general population that Roundup was safe," the lawsuit states."
