Earthworms, Not Chemours, Found to be the Main Source of PFAS inZuid-Holland Eggs
Dordrecht, Netherlands – A new studyconducted by the municipality of Hoeksche Waard has revealed a surprising culprit behind the high levels of PFAS, a group of harmful chemicals, found in eggslaid by hobby chickens in the Zuid-Holland Zuid region. The study, which involved collaboration with the Omgevingsdienst Zuid-Holland Zuid (OZHZ),GGD Zuid-Holland Zuid, Tritium Advies, and Wageningen Food Safety Research (WSFR), has concluded that earthworms, not the industrial giant Chemours, are the primary source of PFAS contamination in these eggs.
The study, published in the journal Environmental Science & Technology, analyzed soil samples, earthworms, and chicken eggs from various locations in the region. The results showed that earthworms, which are a common food source for chickens, contained significantly higher levels ofPFAS than the surrounding soil. This suggests that chickens are ingesting PFAS through their consumption of earthworms, leading to the elevated levels found in their eggs.
Previously, Chemours, a company that manufactures PFAS chemicals, was suspected as the main source of contamination in the region. However, the new studyfound that while PFAS levels in soil near the Chemours facility were higher, they were not significantly higher than those found in other areas of the region. This suggests that the widespread presence of PFAS in the environment, likely from various sources, is contributing to the contamination of earthworms and, ultimately, the eggs.
This study highlights the complex nature of PFAS contamination and the importance of considering multiple sources, said Dr. Jan Willem van der Meer, lead author of the study and researcher at WSFR. While industrial sources like Chemours are a concern, we now know that earthworms play a significant role in the transfer of PFASto chickens and their eggs.
The findings have significant implications for public health and food safety. While the study focused on hobby chickens, the results suggest that commercially raised chickens could also be affected by PFAS contamination through earthworms. This raises concerns about the potential for widespread PFAS contamination in the food chain.
Themunicipality of Hoeksche Waard is now working with local farmers and authorities to develop strategies for mitigating PFAS contamination in the region. These strategies include promoting best practices for chicken farming, such as avoiding areas with high PFAS levels and providing alternative food sources, as well as exploring methods for reducing PFAS levels in thesoil.
This is a complex issue with no easy solutions, said Mayor of Hoeksche Waard, Jan Willem Baas. But we are committed to working with all stakeholders to protect the health of our residents and ensure the safety of our food supply.
