The multinational crop protection corporation responds to organic consumer groups and farm workers who allege the company’s flagship Roundup herbicide causes cancer.

Recently-released internal emails sent between Monsanto employees were “taken out of context,” according to a response from the company’s corporate engagement representative.

Communications between Monsanto employees were released as evidence in a lawsuit filed by California farm workers who allege that glyphosate, the active ingredient in Roundup, causes health problems including cancer.

Some emails alluded to a relationship between Jess Rowland, a now-retired Environmental Protection Agency (EPA) official, and Monsanto regulatory experts. A September 2015 message, quoted in an NPR article, said, “Jess will be retiring from EPA in ~5—6 months and could be useful as we move forward with ongoing glyphosate defense.”

The Organic Consumers Association called on members of Congress to conduct a full investigation into whether or not EPA officials colluded with Monsanto to withhold scientific evidence stating the company’s flagship product potentially could cause cancer.

 “Consumers are told to rely on the EPA to determine the safety of chemicals like glyphosate, and products like Roundup,” said Ronnie Cummins, international director of the Organic Consumers Association in a statement. “When credible sources indicate that EPA officials have deliberately compromised the safety of the public, consumers have a right to know. Monsanto should not be allowed to continue to profit from sales of a product that some EPA scientists, and scientists at World Health Organization, have determined is likely to cause cancer.”
