California, the nation's top agricultural producer, is set to begin monitoring the presence of PFAS—commonly known as 'forever chemicals'—in pesticides used on its farms. Governor Gavin Newsom (D) signed Assembly Bill 1603 into law on Sunday, directing the California Department of Pesticide Regulation to identify and list pesticides containing per- and polyfluoroalkyl substances in the state's public pesticide database.
The legislation marks a notable shift in how the state approaches the intersection of farming and chemical safety. California grows nearly half of the country's vegetables and over three-quarters of its domestic fruits and nuts, making the new tracking system a potential tool for regulators and public health officials to better understand the extent of PFAS exposure through food.
Assemblyman Nick Schultz (D), the bill's author, emphasized the importance of transparency for consumers. "As a father, I don't want my kids eating strawberries contaminated with chemicals that will stay in their bodies for decades," Schultz said in a statement. "I'm thankful Governor Newsom agrees that families deserve to know what's being sprayed on their food."
PFAS are a broad class of synthetic chemicals that resist degradation in the environment and in human tissue, earning them the 'forever' moniker. They are found in everyday items like non-stick cookware, rain gear, and fast-food wrappers, and have been linked to various health concerns, including certain cancers, elevated cholesterol, and immune system disruption.
Initially, the bill included a stricter provision that would have prohibited California regulators from approving any new pesticides containing PFAS. That measure drew strong opposition from agricultural industry groups, who argued it would limit pest control options without sufficient scientific backing.
In a compromise, lawmakers stripped the ban and instead mandated a comprehensive tracking and disclosure system. This approach, Schultz noted, is a "vital step toward ensuring California's agricultural legacy is defined by health and innovation. Tracking and monitoring is the crucial first step." He added, "You can't fix what you can't see."
The new law aligns California with broader efforts to address PFAS contamination, which has become a growing concern for state and federal regulators. The move also comes amid ongoing political battles over state authority and environmental oversight, as California continues to push forward on its own regulatory agenda.
Environmental advocates have praised the law as a necessary first step, though some argue that more aggressive action, such as an outright ban, is needed to fully protect public health. Meanwhile, agricultural groups have signaled they will monitor how the state implements the tracking requirements, hoping to avoid undue burdens on farmers.
The law takes effect immediately, with the Department of Pesticide Regulation expected to begin compiling the PFAS pesticide list in the coming months. This data will be made available to the public, offering a clearer picture of what chemicals are being applied to crops that feed the nation.
