Bayer’s new Roundup products appear more toxic than prior formulations, new report asserts
By Carey Gillam
New types of Roundup weed killing products marketed to US consumers contain chemicals that pose greater health risks to people than prior formulations suspected of causing cancer, according to an analysis by an environmental health advocacy group.
Friends of the Earth (FOE) reported Tuesday it found four chemicals have recently been added to Roundup products that have been scientifically shown to cause a variety of health problems, including reproductive defects, kidney and liver damage, cancer, and neurotoxicity.
The analysis comes after the agrochemical company Bayer pledged that it would remove glyphosate from its popular Roundup herbicide products sold for residential lawn and garden use starting in 2023.
Bayer, which bought Monsanto in 2018, made the change to try to curtail the filing of future litigation as it battles thousands of lawsuits filed against Monsanto by cancer patients who claim they developed non-Hodgkin lymphoma from using Monsanto’s Roundup and other glyphosate-based herbicides.
But FOE said it found the chemicals used in the new Roundup formulations are, on average, 45 times more toxic to humans experiencing chronic exposure than glyphosate-based Roundup. The chemicals were roughly four times more acutely toxic, the group said.
Notably, all four of the added chemicals pose greater risk of long-term and/or reproductive health problems than does glyphosate, based on the Environmental Protection Agency’s (EPA) evaluation of safety studies, FOE said.
Of the four chemicals found in the products – diquat dibromide, fluazifop-P-butyl, triclopyr, and imazapic – the “worst offender”, according to FOE, is diquat dibromide. It is 200 times more toxic than glyphosate when exposure occurs over a long period of time, the group said, and is banned in the European Union. It is 27 times more toxic in acute exposures, the group said.
Kendra Klein, FOE deputy director for science and an author of the report, said the Environmental Protection Agency (EPA) should be providing stronger oversight.
“People need to realize that the EPA has long put the profits of companies like Bayer ahead of their health when it comes to pesticides,” Klein said. “And now, they’ve allowed Bayer to quietly swap out the chemicals in Roundup, making it far more toxic to people’s health, without changing the packaging or warning consumers of the increased risks.”
