Monsanto currently faces lawsuits from an American farm worker and horticultural assistant who claim that Roundup caused their cancers. Just six months ago, the World Health Organization (WHO) classified the weed-killing ingredient in Roundup, glyphosate, as “probably carcinogenic to humans.”

Attorneys expect hundreds of lawsuits to be filed against the corporation as Roundup is the most popular herbicide on the planet. WHO recognition of the danger of glyphosate gives support to the claims these plaintiffs are bringing against Monsanto.

“I believe there will be hundreds of lawsuits brought over time,” said attorney Robin Greenwald to Reuters.

Monsanto disputes the WHO’s designation and claims that the lawsuits are without merit.

“Decades of experience within agriculture and regulatory reviews using the most extensive worldwide human health databases ever compiled on an agricultural product contradict the claims in the suit which will be vigorously defended,” said Charla Lord, spokeswoman for Monsanto.
