Citing new science, groups petition EPA to suspend glyphosate weed killer

By Carey Gillam

Citing new scientific research, a coalition of farmworker, public health and environmental advocates on Wednesday filed a legal petition with US regulators demanding they immediately suspend authorization for the controversial weed killing chemical called glyphosate.

The petition, filed with the US Environmental Protection Agency (EPA), alleges that the chemical does not meet the required safety standard set by federal law and the EPA has “no valid assessment demonstrating otherwise.”

If the EPA fails to address the petition, the groups said they will take the agency back to court, where the groups last year successfully garnered a judicial finding that the EPA’s most recent assessment of glyphosate was deeply flawed.

The legal petition comes less than 10 days after the publication of a new scientific study that lends fuel to critics who say glyphosate herbicide products can cause cancer.

In a paper published Dec. 6, National Institutes of Health cancer scientists said they found markers of genotoxicity in male farmers with high uses of glyphosate. The authors said their work suggested glyphosate ‘could confer genotoxic” effects, and amount to “novel evidence regarding the carcinogenic potential of glyphosate.” The study was published in the journal Environmental Health Perspectives.

The journal also published an accompanying opinion article from environmental and occupational health researchers who called the new study “important new evidence” that should be considered in evaluating glyphosate safety. The study was the largest of its kind and provides “mechanistic support for genotoxicity of glyphosate,” the researchers wrote.

“There is really compelling new science out there,” said Bill Freese, science director with the Center for Food Safety, the group leading the legal petition. “It’s becoming increasingly untenable for the agency to deny the cancer hazard.”

In addition to multiple studies cited as evidence of a cancer connection, “numerous studies” show glyphosate has harmful impacts on the liver, kidney and reproductive system, according to the petition.

California pushes ahead with its new pesticide-reduction plan

By Pam Strayer and Carey Gillam

Amid mounting evidence of the risks some synthetic pesticides pose to human and environmental health, California regulators this week were pushing ahead with a recently announced “roadmap” aimed at transitioning the state to more sustainable options for managing weeds and insects,

The California Department of Pesticide Regulation (DPR), in partnership with the California Department of Food and Agriculture (CDFA), held two public webinars on Thursday seeking to explain the details of the plan – and bolster support for it – as the state nears the March 13 close of the public comment period on the proposal.

State officials announced the plan in January, saying the goal is to eliminate the use of “high-risk pesticides” by 2050 to “better protect the health of our communities and environment, while supporting agriculture, food systems and community well-being.”

That message was underscored in Thursday’s event: “The evolving science about risks and impacts from certain pesticide uses on our health and our environment, which too commonly impacts communities already overburdened by other environmental hazards, point to the importance of accelerating this system-wide shift,” Clare Mendelsohn deputy secretary for public policy at California Environmental Protection Agency, said in the evening webinar.

State officials say the Sustainable Pest Management (SPM) plan is visionary and will significantly overhaul harmful agricultural practices in the state, helping protect farmworkers and others put at risk through exposure to pesticides known to be harmful to human health.

CDFA Secretary Karen Ross has said that once implemented, the recommendations would “ensure an abundant and healthful food supply, protect our natural resources, and create healthy, resilient communities.”

But some say the plan falls short in many respects, and that faster and more aggressive actions are needed to protect and enhance soil health, adapt to climate change, and protect human health.

Citing birds and bees, groups petition EPA to close pesticide loophole

By Carey Gillam

The US should overhaul regulation of a class of insecticides tied to excessive honeybee and bird deaths, according to a citizen petition filed Wednesday with the Environmental Protection Agency (EPA) by a coalition of more than 60 nonprofit groups.

Specifically, the groups are demanding the EPA revoke a nearly 40-year-old waiver that allows pesticide companies to bring their products to market without first providing data that proves the product benefits. The groups say the waiver dates back to a 1984 EPA declaration that stated: “rather than require efficacy data the Agency presumes that benefits exceed risks”.

The petition, which was submitted by Public Employees for Environmental Responsibility (PEER) and the American Bird Conservancy, is aimed at turning back the use of insecticides known as neonicotinoids, or neonics, which many studies have shown to be exceptionally harmful to hundreds of species.

Environmental advocates say numerous studies show neonics are not necessary and are so detrimental to the environment that they should be banned.

“This stuff is causing all sorts of environmental problems and the environmental tragedy is multiplied because in many cases these insecticides provide farmers no benefit but at the same time they’re doing all this damage,” said Peter Jenkins, a lawyer with PEER.

The European Union has banned the outdoor use of certain types of neonics, and the United Nations has said neonics are so hazardous that they should be “severely” restricted. But in the US, the pesticides remain widely used, typically as coatings on corn and soybean seeds planted by farmers to protect crops from insects and disease. Neonicotinoids are used across on an estimated 150m acres of US farmland annually.

When used as seed coatings, neonics are absorbed through the roots of plants as they grow. Residues of the chemicals can persist for years in the environment and are blamed, along with other pesticides, for a so-called “insect apocalypse.”
