Roundup's label still doesn't warn buyers that the weed killer's main ingredient is a probable human carcinogen. We need to tell the EPA that Monsanto should come clean about the dangers of its products.

ACT NOW

Anonymous,

Wouldn't you want to know the risks of the world's most commonly used agricultural chemical before you used it?

The label on Monsanto's weed killer, Roundup, claimed that its main active ingredient, glyphosate, only affects an enzyme found in plants.1 In a lawsuit settlement in March, Monsanto agreed to remove that language from Roundup's label after consumers alleged that the chemical attacks an enzyme in humans, too.2

But even with that language removed, Roundup's label still fails to warn consumers about glyphosate's health risks -- including the fact that the World Health Organization has determined it's a "probable human carcinogen."3

Monsanto should warn consumers about the risks of Roundup. Tell the Environmental Protection Agency to order Monsanto to include Roundup's link to cancer on its label.

A federal jury in San Francisco found last year that Roundup was a "substantial factor" in causing a man's cancer.4 That decision came less than a year after a different California jury awarded about $78 million to a former school groundskeeper who got terminal non-Hodgkin's lymphoma after using Roundup.5 In fact, as of late 2019, Monsanto was facing lawsuits from over 40,000 plaintiffs.6

Monsanto shouldn't be allowed to exclude the dangers of Roundup from the product's label, especially when juries and the World Health Organization alike have consistently seen a strong link between glyphosate and cancer.

It's time for Monsanto to come clean about Roundup's cancer risks. Add your name today.

In the United States, public parks, playgrounds, schools, and gardens are sprayed with 26 million pounds of Roundup every year.7 And in fact, the amount of glyphosate used in America's public spaces each year has been steadily increasing since 1974.8 If a product that we interact with so ubiquitously poses a threat to our health, we should know about it.

Numerous U.S. cities and counties -- including Boulder, Colorado; Charlottesville, Virginia and Portland, Oregon -- have issued outright bans or significant restrictions on Roundup and other glyphosate-based herbicides.9 Entire countries have even begun to restrict, outlaw or phase out glyphosate use, including Germany, France, Austria, Italy and more.10 Still, Roundup's label fails to warn buyers that glyphosate is a probable human carcinogen.

Tell the EPA: Monsanto needs to stop endangering public health and put Roundup's link to cancer on its warning label.

Thank you,
