In 2016, the UN's Food and Agricultural Organization and the World Health Organization found that the chemical was "unlikely" to pose a risk to humans through food.
Glyphosate was even found in a few organic products, though most had non-detectable levels.
I don't think I need to detail the problems with Monsanto's weed-killing Roundup here.
However, Naidenko, who was not an author of the report, believes that there are "conflicts of interest standing behind some" of the positive opinions of glyphosate and that Monsanto has tried to influence the EPA so that it will continue to allow use of the chemical in the United States.
Johnson's case is the first of a long list of about 4,000 people looking to sue the weedkiller maker for similar allegations.
Cheerios, Lucky Charms and Quaker Oats were among the products found to have glyphosate levels above the EWG's health benchmark of 160 parts per billion - meaning it's higher than what the group deems safe for children. More than two-thirds of the samples returned levels of glyphosate above what EWG considers safe for children.
Familiar breakfast foods and snacks contain potentially unsafe amounts of a weed-killing chemical, according to a new study.
"We don't know a lot about the effects of glyphosate on children", said Lowry, "And essentially we're just kind of throwing it at them". "No one wants to eat a weed killer for breakfast, and no one should have to do so".
General Mills also responded to the findings in a statement sent to Fast Company.
The World Health Organization says glyphosate is a "probable carcinogen". "The government must take steps to protect our most vulnerable populations".
General Mills and Quaker Oats are relying on outdated safety standards used by a government agency that is notorious for neglecting new science on chemicals.
Organic products had lower levels of glyphosate; and nearly two-thirds of the samples made with organically grown oats didn't have any detectable glyphosate at all. "And depending on weather patterns it could drift into their farms and get onto their foods", she said.
And herbicides may increase a child's risk for cancer.
In response to EWG's report, a Monsanto spokesperson said, "Even at the highest level reported by the EWG (1,300 ppb), an adult would have to eat 118 pounds of the food item every day for the rest of their life to reach the EPA's limit".
There was some evidence suggesting that people who used glyphosate in their jobs might have a higher rate of acute myeloid leukemia, but the numbers were too low to say for sure and the team said more study of that particular question would be needed. Monsanto, the company that makes RoundUp, said it would appeal the verdict, insisting that its product is safe.
"Of course, nobody eats close to that much food!" As Cook points out, "It's up to consumers to call on companies to rid their products of glyphosate".
"If you look at the study some of the organic cereals also had elevated levels of glyphosates present and it's not because the organic farmers have sprayed the glyphosate".
