European food safety authority cuts acceptable dose of forever chemical in water
The European Food Safety Authority (EFSA) has significantly reduced the acceptable daily intake (ADI) for trifluoroacetic acid (TFA), a persistent pollutant found in water. TFA is the smallest and most persistent compound within the broader PFAS family of chemicals, often referred to as "forever chemicals" due to their extreme longevity in the environment. A 2025 study by the French Agency for Food, Environmental and Occupational Health & Safety (Anses) revealed that TFA was present in a substantial 92% of water samples analyzed across France. This new directive from the EFSA aims to address growing concerns about the widespread presence and potential health impacts of such persistent chemicals in drinking water supplies.
The EFSA's decision to lower the acceptable intake of TFA reflects a growing global awareness of the pervasive nature and potential health risks associated with PFAS compounds. This regulatory adjustment signals a shift towards more precautionary public health measures in response to scientific findings on environmental contaminants. The challenge for regulatory bodies moving forward will be to balance the need for stringent environmental and health standards with the practicalities of water treatment and industrial compliance, particularly given the persistence of these chemicals. This move may also spur further research into more effective remediation technologies and alternative substances across various industries that utilize PFAS.
