Per- And Polyfluoroalkyl Substances in Seafood
The U.S. Food and Drug Administration (FDA) is launching a new investigation into the contamination of seafood by per- and polyfluoroalkyl substances (PFAS), a class of chemicals that have earned the moniker “forever chemicals†due to their remarkable persistence in both the human body and the environment. The aim is to evaluate the levels of PFAS in seafood and understand how they contribute to public health risks, particularly through dietary exposure.
As part of this investigation, the FDA has issued a formal request for scientific data regarding the concentrations of PFAS in seafood, as well as in the surrounding environment, including processing water. The agency is also seeking information on effective mitigation strategies to reduce exposure to these chemicals within the food supply chain. This step comes in response to mounting concerns over PFAS, which have been linked to various serious health conditions, including thyroid disease, kidney cancer, and testicular cancer.
PFAS are a vast class of thousands of compounds, commonly found in a wide range of products, from nonstick cookware and water-repellent fabrics to fire-fighting foams and food packaging. Unfortunately, many of these chemicals have entered drinking water systems and food supplies through waste streams, contaminating the environment and posing a potential health hazard. According to the FDA, seafood may be particularly vulnerable to contamination compared to other food types, based on internal testing and data gathered from the agency’s Total Diet Study as well as additional surveys targeting the nation’s most consumed seafood.
Addressing the potential effects of PFAS exposure has become a national priority. The FDA’s investigation is part of a coordinated effort across multiple federal agencies to identify the routes of PFAS exposure, assess the associated health risks, and ultimately reduce public dietary exposure to these chemicals. The agency emphasized that it will continue collaborating with a wide range of stakeholders, including seafood industry professionals, academic researchers, and state and federal health authorities, to advance scientific understanding and reduce PFAS contamination in seafood.
The FDA’s move to engage with experts from various sectors underscores the complexity of addressing PFAS contamination. Seafood is a critical source of nutrition for many Americans, and any findings linking these chemicals to public health risks could have significant implications for both the seafood industry and consumer behavior. The FDA has also stated that it will focus on understanding the variations in PFAS levels across different types of seafood and work towards strategies to mitigate exposure.
In its statement, the FDA highlighted its commitment to applying the latest science in order to understand the levels of PFAS in seafood and the potential risks these contaminants pose to public health. The agency’s findings will likely inform future regulatory actions and consumer guidelines concerning seafood safety.

The FDA’s investigation into PFAS contamination in seafood underscores a critical, yet often overlooked, public health issue. These “forever chemicals” are indeed a major environmental and health challenge, especially as their pervasive presence in the food supply system becomes more widely acknowledged. The FDA’s focus on seafood is particularly notable, as it reflects an emerging concern about the broader implications of PFAS exposure through diet.
PFAS, with their ability to accumulate in the body and resist environmental breakdown, are a serious risk factor for a range of chronic diseases, including cancers and hormonal disruptions. Their persistence in the ecosystem, especially in water sources, highlights the difficulty of eradicating these substances once they have entered the food chain. Seafood, often seen as a healthy dietary choice, is now emerging as a potential source of PFAS exposure, raising concerns among both consumers and industry stakeholders.
One of the more intriguing aspects of this investigation is the FDA’s reliance on collaboration with a broad spectrum of stakeholders, including academia and state and federal agencies. This approach reflects the multi-disciplinary nature of tackling PFAS contamination, which involves not just understanding the levels of chemicals in seafood, but also the environmental pathways through which they enter the food supply. By gathering input from diverse sectors, the FDA is positioning itself to develop a more comprehensive strategy for reducing PFAS exposure.
However, there are challenges ahead. The vast diversity of PFAS compounds means that any mitigation strategy will need to be highly nuanced. The variations in PFAS concentrations across different types of seafood, as noted in the FDA’s request for information, suggest that a one-size-fits-all solution is unlikely. Moreover, while mitigation strategies can be developed to limit exposure in processing and farming, addressing PFAS contamination at the environmental level will be a much larger and more complex issue.
The FDA’s commitment to applying the latest science is commendable, but the path forward will require not just scientific research but also robust public engagement. Consumers need clear, actionable information about the risks of PFAS in seafood, and the industry needs guidance on best practices to prevent contamination. Additionally, further regulatory action will likely be necessary, especially if widespread contamination is confirmed.
Ultimately, the FDA’s inquiry is a much-needed step toward addressing a persistent environmental toxin that has remained under the radar for too long. As this investigation unfolds, it will be crucial for the agency to work swiftly and transparently to protect public health while also ensuring that the safety and sustainability of the seafood supply are not compromised. The results of this investigation could not only reshape the future of seafood consumption but also set important precedents for handling chemical contamination in other sectors of the food industry.
