On March 20, 2020, the Natural Resources Defense Council challenged the EPA’s ID in the U.S. Court of Appeals for the Ninth Circuit. In May 2021, the EPA requested—and the court granted--a partial voluntary remand without vacatur of the ecological portion. The EPA later withdrew the entire ID, and now glyphosate remains under reconsideration.
As of 2026, the EPA maintains that there is no evidence glyphosate causes cancer in humans, no indication it acts as an endocrine disruptor, that residue on food items are safe for consumption, and that ecological risks are low, with the exception of potential harm to bees.
Despite these conclusions, public skepticism remains high. The widely publicized Monsanto Roundup litigation—through which Monsanto has paid nearly $11 billion to tens of thousands of plaintiffs alleging cancer caused by Roundup—has intensified doubts about the EPA’s position. Additionally, organizations such as the Environmental Sciences Europe and the World Health Organization have criticized the EPA for failing to adequately consider individuals with heightened exposure, such as farmworkers and nearby residents. The Center for Food Safety has also cited emails between an EPA scientist and a Monsanto officer that suggest “coordinated efforts to undermine the legitimacy of IARC’s… determination.”

On February 18, 2026, President Trump signed an executive order titled “Promoting the National Defense by Ensuring an Adequate Supply of Elemental Phosphorus and Glyphosate-Based Herbicides.” A related fact sheet states that the order is intended to “protect domestic production of elemental phosphorus and glyphosate-based herbicides” which is “essential to military readiness and America’s agricultural strength.” The fact sheet emphasizes that there is currently only one domestic producer of elemental phosphorus and glyphosate-based herbicides and the demand in the U.S. far exceeds current output, which “gravely endangers national security and defense” including food-supply security.
A particularly controversial provision of the order grants immunity to domestic producers that comply with federal law.

Environmental groups, such as the Waterkeeper Alliance, have strongly criticized the order arguing that “it puts chemical industry profits above public health and clean water.” Granting immunity for industrial chemical producers that follow federal directives makes it harder to hold them accountable for harm to human and environmental health. As discussed in this prior blog post, critics also point to broader legislative trends—such as provisions in the recent farm bill—that may weaken environmental protections, including removing dozens of pesticides from health and environmental safety reviews, granting the USDA power to block EPA health and environmental safeguards, removing Clean Water Act protections that limit pesticide pollution, etc.
However, there are signs of legislative pushback. On February 20, 2026, Representatives Thomas Massie (KY) and Chellie Pingree (ME) introduced the bipartisan “No Immunity for Glyphosate Act” to Congress in effort to undo the February 18 executive order. Representative Pingree stated “If there was ever any doubt about whose side this Administration is on, this Executive Order makes it crystal clear: Big Chemical comes first, and the health of Americans comes last.” Representative Massie similarly argued that “If the goal is to 'Make America Healthy Again,' the federal government should not be using its authority to promote or protect the production of glyphosate.”

The No Immunity for Glyphosate Act was introduced to Congress shortly before a disruptive report from the Iowa Environmental Council and the Harkin Institute for Public Policy and Citizen Engagement titled “Environmental Risk Factors and Iowa’s Cancer Crisis” was released on March 25, 2026. The report focuses on pesticides, PFAS, Nitrate, Radon, and other industrial contaminants in Iowa. The Executive Director of the Iowa Environmental Council stated that the report “demonstrates clear links between environmental pollution and our health and well-being.”

Iowa’s cancer rate exceeds the national average by more than 10%, with a particularly elevated rates among individuals under 50. The state has the highest number of concentrated animal feeding operations (CAFOs) in the country, a number more than 2.5 times as many CAFOs than the next highest state. With emerging research linking glyphosate and other environmental contaminants to adverse health outcomes, pressure is mounting for legislative action—and soon.
