This study was conducted to assess PFAS use and unintentional contamination in paper, cardboard, and plant- based food packaging and tableware from 17 countries across Asia, Africa, Europe, Latin America and the Caribbean, and to contribute to the achievement of the universal ban of all PFAS internationally. Setting legislative thresholds for a few small groups of PFAS is not sufficient to control these harmful substances in food packaging. Only a universal ban, including polymeric PFAS, can stop human exposure and release from food packaging. Therefore, the most efficient control measure for reducing the release of PFAS into the environment and for avoiding hazardous (so-called “regrettable”) PFAS substitutes is to have a complete global ban by the Stockholm Convention and national governments.
