Second Wyoming man files lawsuit against Monsanto, alleges Roundup gave him cancer

A second Wyoming man has filed a federal lawsuit against agribusiness giant Monsanto, alleging its popular weedkiller brand Roundup caused him to develop non-Hodgkin’s lymphoma.


Gerald Kubena, of Casper, alleges in the lawsuit filed last week that he used Roundup from 2009 through 2018 on his property. He was diagnosed with the lymphoma in December, which he alleges “was proximately and actually caused by exposure to (Monsanto’s) Roundup products.”


The lawsuit seeks $1 million in damages.

Monsanto has previously denied the allegations, telling the Star-Tribune in February that the herbicide has “been used safely and successfully for decades” and that Bayer, Monsanto’s parent company, “stands behind these products and will vigorously defend them.”
