FDA finds detectable PFAS in 8 of 91 seafood samples in 2024 Total Diet Study
The Food and Drug Administration's latest Total Diet Study analyzed 91 samples across the U.S. food supply for 28 PFAS compounds. Detectable levels appeared in clams, chicken breast, cod, shrimp, salmon, catfish, tilapia, and ground beef — consistent with prior surveys showing fish and shellfish as primary dietary exposure routes.
Browse by chemical class
Four classes of synthetic chemicals dominate food-contamination research. Each links to a full encyclopedia and every food where it has been detected.
A class of approximately 15,000 synthetic chemicals, valued for stain, water, and grease resistance. Persistent in the environment and the human body.
Plastic fragments smaller than 5 mm, formed as larger plastics break down or shed during use. Detected across the food supply.
Plasticizers used to soften PVC and other plastics. Some are endocrine disruptors. Detected in 86% of U.S. food samples in 2024.
Used to manufacture polycarbonate plastics and epoxy resin can linings. Endocrine-disrupting activity well established for BPA.

How this database works
What we aggregate
FDA Total Diet Study, EPA UCMR 5, peer-reviewed academic research, Consumer Reports investigations, and independent lab testing — normalized into one searchable structure.
What we don't do
We do not invent or interpret results. Every value displayed traces to its source study with full citation. We never compare values across measurement methods that aren't directly comparable.
Updated continually
New FDA datasets, EPA testing rounds, and high-profile studies are ingested within 30 days of publication. Last update: May 14, 2026.
