EU food safety agency lowers safe daily intake of 'forever chemical' TFA

EFSA stated that the revision was based on new scientific evidence indicating that TFA can alter levels of thyroxine, a hormone produced by the thyroid gland that plays a vital role in regulating bodily functions. TFA is a type of perfluoroalkyl and polyfluoroalkyl substance (PFAS), which are known for their longevity in the environment. These chemicals are used in various products, including kitchenware, medical devices, and defense equipment, but their widespread use raises concerns about potential risks to human health and the environment.

According to EFSA, TFA can form as a breakdown product of other PFAS substances, including certain active ingredients in pesticides. This process can lead to TFA entering groundwater, soil, and agricultural crops. EU member states are mandated to monitor PFAS levels in drinking water, with additional monitoring programs in place for food. EFSA, in collaboration with the European Chemicals Agency, is continuing its investigation into the breakdown pathways of PFAS into TFA and its environmental behavior, with findings expected by next summer.
