Animal products contain highest levels

The study analyzed 76 different PFAS compounds found in various food categories sold locally. Researchers determined that concentrations were often high enough to match or exceed daily intake from drinking water. Average levels measured approximately 1.9 nanograms per gram in fish and 1.3 nanograms per gram in seafood.

Meat and dairy also tested

Meat samples showed an average concentration of 1.2 nanograms per gram during the analysis. The team noted that these animal-based products generally held higher amounts than plant-based alternatives. These results highlight another significant path for human exposure to persistent chemicals.
