A federal court hearing in San Francisco will turn a public spotlight on to the science surrounding the safety of one of the world’s most widely used pesticides, a weedkilling chemical called glyphosate that has been linked to cancer and is commonly found in our food and water, even in our own bodily fluids. Given the broad health and environmental implications tied to the use of this pesticide, we would be well served to pay attention.
As the active ingredient in Monsanto’s branded Roundup and hundreds of other herbicides, glyphosate represents billions of dollars in annual revenues for Monsanto and other companies, and is prominently used by farmers as an aid in food production. It’s also favored by cities for keeping public parks and playgrounds weed free, and by homeowners who want a tidy lawn. But the chemical was deemed a probable human carcinogen by the World Health Organization’s cancer experts in 2015 in a finding that has since triggered waves of liability lawsuits against Monsanto.
Monsanto has tried to persuade US judge Vince Chhabria to throw out the litigation, and sought to keep secret the many internal documents it has been forced to turn over in discovery. But Chhabria has ordered that the hearing be video-recorded and shared publicly over the internet. And he has granted permission for plaintiffs to explore in open court such things as the ghostwriting of science as well as a controversial 1983 study that EPA scientists at the time said showed evidence of glyphosate’s cancer-causing potential.
