Workshop on the latest advancements of PFASs risk assessment

Per‐ and polyfluoroalkyl substances (PFASs) comprise a large group of chemicals, which are extremely persistent and are likely to remain in the environment for extended periods, raising concerns about their long‐term impact on both human health and the environment. On the 17^th November 2025, EFSA organised an online workshop that brought together EU and international agencies, Member States, universities, public research institutes, industry stakeholders and NGOs active in the risk assessment of PFASs, with the aim to share knowledge and to identify opportunities for future collaboration and synergies amongst stakeholders. Ongoing scientific assessments of PFASs were shared, followed by different perspectives from stakeholders. General discussions outlined the current scientific and methodological gaps, the high number and the complexity of PFASs to be addressed. PFASs pose a complex and long‐standing scientific and regulatory challenge that requires coordinated actions across disciplines, sectors and organisations. Continued dialogue, collaboration, engagement, capacity building and communication are essential to foster a strong community of practice and to translate scientific knowledge into effective protection of human health and the environment.
