The ruling in the case Monsanto v. Durnell shields pesticide manufacturers like Bayer–Monsanto, the maker of glyphosate-based Roundup, in failure-to-warn lawsuits. A legal expert explained to Food Safety Magazine how this decision potentially weakens state right-to-know chemical health warning laws like California's Proposition 65.
The Paraquat Prevention Act would cancel all EPA-registered uses of the herbicide and permanently prohibit its reregistration. More than 70 countries, including the EU and China, have banned the domestic use of paraquat, although China still manufactures and exports the chemical to the U.S.
With two proposed rules issued on May 18, the Trump EPA followed through on its stated intent to rescind or extend the compliance date for Biden-era drinking water limits for several “forever chemicals” of concern.
Arguing that states’ authority to require pesticide health warnings is critical to filling gaps in EPA oversight and risk communication, a coalition has filed an amicus brief in the U.S. Supreme Court case Monsanto v. Durnell, in which Monsanto (now Bayer), the maker of glyphosate-based Roundup, seeks to strike down that authority.
EPA has announced its sixth Contaminant Candidate List, which includes PFAS, microplastics, pharmaceuticals, disinfection byproducts, and other chemicals and microbes. Concurrently, HHS unveiled its Systematic Targeting Of MicroPlastics (STOMP)
initiative to address and understand microplastics in the human body.
EPA repealed Biden-era amendments that had tightened emissions regulations under the Mercury and Air Toxics Standards (MATS) rule. Critics warn that this decision could lead to greater bioaccumulation of the neurotoxin methylmercury in fish, increasing human dietary exposure.
A paper from the year 2000 suggesting the safety of glyphosate (the active ingredient in herbicide Roundup), which has been cited for decades in regulatory decisions and pesticide approvals, has been retracted after litigation revealed undisclosed conflicts of interest undermining the study’s integrity.
EVOCA, a new biofungicide from Biotalys, has received regulatory approval from EPA, and has also been exempted from maximum residue limits based on its safety profile.
In May 2025, EPA rolled back Biden-era drinking water limits for per- and polyfluoroalkyl substances (PFAS) of concern. A new map visualizing EPA testing data shows that more than 30 million Americans are served by drinking water systems containing one of four PFAS for which the limits have been revoked.
In this episode of Food Safety Matters, we speak to industry attorney Alfredo Fernández about what the new Toxic Substances Control Act and emerging state legislation mean for food manufacturers, importers, and businesses regarding compliance with U.S. requirements for per- and polyfluoroalkyl substances (PFAS) in food contact materials and packaging.
