Is it safe to eat foods with multiple PFAS signatures from plant and animal sources combined?

What's actually in it

Food sources of PFAS include fish and seafood (concentrating PFAS from water), leafy vegetables and grains grown in contaminated soil, dairy and meat from animals eating contaminated feed, eggs from hens on contaminated farms, and fruits grown with PFAS-containing pesticides. A typical meal can hit 3-4 of these categories.

Plants absorbing PFAS from soil is relatively newer research territory. Leafy greens and root vegetables are the worst offenders.

What the research says

A 2026 review in J Agric Food Chem examined the potential of food plants to contribute to human intake of PFAS. Plants absorbed PFAS from soil and water at measurable rates, with several crops accumulating at levels concerning for regular consumers. The contribution from plants to total PFAS intake was larger than previously assumed.

Reducing total PFAS intake requires attention across food categories: lower-PFAS fish (sardines, anchovies), organic vegetables from clean-soil farms, grass-fed meat from farms without biosolid fertilizer history, and eggs from certified organic operations. The EPA maps areas with known PFAS contamination, which helps when sourcing local food. For families, reducing meat and dairy frequency alongside organic produce choices cuts PFAS intake meaningfully.
