The Environmental Working Group’s latest analysis flags a notable presence of PFAS pesticide residues in non-organic produce across California. That includes crops many Marin County shoppers rely on.
Based on 930 samples covering 78 types of fruits and vegetables, the study finds PFAS residues in about 37% of conventional produce. Stone fruits and berries show especially high exposure.

For folks in San Rafael, Mill Valley, Sausalito, and beyond, these findings raise practical questions. People want to know how to source, wash, and choose produce from the North Bay and the wider Bay Area.
What the California PFAS findings mean for Marin households
Roughly 37% of non-organic produce sampled contained at least one PFAS pesticide residue. Researchers tested 930 samples from 78 conventional crops, and PFAS turned up in 348 samples across about half of the crop groups.
For Marin families shopping at the San Anselmo farmers market or the Marin City co-op, these numbers make mindful sourcing and careful handling of produce feel pretty important.
Stone fruits got hit hard: fludioxonil showed up on more than 90% of nectarines, plums, and peaches. Lemons also showed high levels.
Berries didn’t fare much better. Cherries, strawberries, and grapes carried PFAS in about 80% of samples, often with several PFAS compounds present. If you’re shopping at the Larkspur markets or West Marin stalls near Point Reyes Station, that’s worth knowing.
What the study revealed about PFAS variety and where they show up
Let’s break down the report’s main points, using data from the California Department of Pesticide Regulation and EWG’s analysis. Researchers say this trend isn’t getting better.
- Four or more PFAS chemicals turned up on celery, collards, and bell peppers.
- Some strawberries had as many as 10 different PFAS compounds.
- In total, 53 PFAS pesticides were found on California crops, with 23 already banned in the European Union. EFSA is thinking about restricting fludioxonil further.
- California doesn’t have a statewide PFAS pesticide rule yet. Maine and Minnesota have bans, but in California, counties like Fresno, Kern, and San Joaquin use more PFAS in certain areas.
For Marin residents, it’s worth keeping an eye on where your produce comes from and how it’s grown. Even though this reflects 2023 data, local buyers at markets in Novato or Corte Madera might want to know more about growers’ practices and whether they’re certified organic.
Practical steps for Marin shoppers: buying and washing smart
If you’re wandering the farmers markets in Fairfax and San Rafael or filling a grocery bag in Tiburon, you can take steps to cut your exposure and still support local agriculture.
Shopping smarter near San Rafael and San Anselmo
- Buy organic when possible: Organic standards don’t allow PFAS pesticides. That’s a straightforward way to lower exposure for Marin and North Bay households.
- Wash produce thoroughly: Washing won’t get rid of all residues, but better washing routines can reduce surface PFAS on non-organic items, like those from Corte Madera markets.
- Peel or limit high-risk items: For stone fruits and leafy greens, peeling or going organic might help lower contact with PFAS residues.
- Ask questions at your market: In San Rafael and elsewhere, talk with farmers about pest-management practices. See if they use integrated pest management or follow organic standards, which are pretty common around the Bay Area.
Policy landscape and the road ahead for Marin and California
California doesn’t have a statewide PFAS pesticide regulation right now, even though several other states have banned them. The EWG analysis points out that 2023 DPR data show some concerning trends in PFAS use.
Certain counties in California are using these chemicals more heavily. Marin, with its water feeding into the San Francisco Bay, faces pressure from both policymakers and residents to push for tighter oversight and safer farming practices.
People here want to protect drinking water and coastal ecosystems near places like Sausalito and Tomales Bay. It’s not just about policy—there’s a real sense of responsibility to keep these areas clean and safe.
Experts say there’s no need to panic. Marin’s best move might be to lean into organic options when possible and wash produce carefully at home.
Folks should keep advocating for strong standards that protect coastlines, waterways, and families from San Geronimo to Ross. And honestly, making informed choices at the farmers markets in San Anselmo, Mill Valley, and Tiburon? That’s how local farms and Marin’s unique way of life keep thriving.
