Massive damage awards in previous cases are triggering a new onslaught against the chemical company.

Dozens of lawsuits potentially worth tens of millions of dollars in damages are in the works in Hawaii targeting Monsanto Co. and its weed-killer Roundup, lawyers who have filed two of the lawsuits said.

Michael Green, who filed a federal products liability suit earlier this month against Monsanto, said he expects to file at least six or seven more suits in the next several weeks alleging Roundup caused his clients to develop a form of cancer called non-Hodgkins lymphoma.

Meanwhile, Brian Mackintosh, a former associate of Green’s who has filed a similar suit in state court, said he has an additional 35 clients lined up.

The Hawaii lawsuits come as Monsanto, which is now owned by the German chemical firm Bayer AG, faces thousands of similar actions across the U.S.
