Imported Seafood May Raise PFAS Exposure Risks For American Diets

Most seafood on American plates travels thousands of miles before it is eaten. That journey matters more than many people realize. A new global study suggests imported fish can expose U.S. consumers to higher levels of toxic forever chemicals called PFAS.

According to Amudalat Ajasa, researchers publishing in Science modeled how PFAS build up in marine fish and then move through global trade to dinner tables. The study tracked two common PFAS chemicals across 212 fish species and 44 countries over more than a decade. You can read the full study here.

The results are troubling. Fish caught in parts of Asia and the Pacific carried the highest concentrations of PFAS. Yet people in North America still consumed the most overall because seafood intake is higher. These chemicals persist in the environment and do not break down easily. Once they enter oceans, they accumulate in fish and other animals over time.

PFAS exposure has been linked to cancer, immune system damage, and other serious health concerns. Larger predatory fish tend to carry higher levels, while widely eaten species like cod and herring drive most exposure simply due to volume. Because about 85 percent of seafood eaten in the United States is imported, tracing contamination becomes difficult.

The findings raise broader questions about how global trade shifts Pollution risks around the planet. Even if environmental rules improve in one region, contaminated fish can still move freely across borders. That reality affects not only people but also marine ecosystems and coastal wildlife.

Experts stress this is not a reason to panic or stop eating fish. It is a reminder to ask where food comes from and how often it is consumed. Many advocates also point out that a more plant based or vegan diet can reduce exposure while easing pressure on the Earth.
