Eating PFAS-Contaminated Meat Spiked Blood Levels to 48 ng/mL

People in Denmark ate veal from cattle that grazed near a firefighting training site. Their median PFOS blood level hit 48.8 ng/mL. For reference, the general population average is around 4 to 5 ng/mL.
How It Happened
A 2026 study in Environ Int investigated people in Korsør, Denmark, who ate meat from cattle raised near a contaminated site. The cows grazed on land polluted with PFAS from firefighting foam. The meat was distributed to members of a local grazing association.
Blood tests from 200 participants showed median PFOS levels of 48.8 ng/mL and PFHxS levels of 3.14 ng/mL. Some people had PFOS levels as high as 164.7 ng/mL. The more meat someone ate, the higher their blood levels. A clear dose-response relationship.
PFAS in the Food Chain
PFAS from firefighting foam soaked into the soil. Grass absorbed it. Cattle ate the grass. People ate the cattle. Every step concentrated the chemicals further. This is how PFAS moves through the food chain, and it happens anywhere contaminated land is used for agriculture.
This isn't just a Denmark problem. Military bases and airports around the world have used PFAS-containing foam for decades. Farmland near these sites is at risk.
What You Can Do
Know where your meat comes from. Support farms that test for contaminants. Filter your drinking water. Avoid meat from areas near military bases, airports, or industrial sites with known PFAS contamination. Choose non-toxic kitchen alternatives to reduce PFAS exposure at every meal.
