FDA investigation of PFAS in processed foods
On August 26, the FDA published the results of tests carried out on processed foods to measure the levels of per-and polyfluoroalkyl (PFAS). Perfluoroalkyl substances (PFAS) are a family of chemical compounds used mainly by industry. In the food sector they are used in the production of paper and cardboard for packaging.
The analysis was carried out on different types of foods highlighting that 164 of the 167 samples did not contain detectable levels of these substances. PFAS have been detected in 3 samples of fish sticks, canned tuna and protein powder. However, these results cannot be used to draw definitive conclusions on human exposure as sample quantities were limited and the degree of contamination varies according to the type of PFAS and how the products are stored.
The FDA investigation of PFAS in processed foods is among the first studies in this area and is a major step forward in testing and analyzing PFAS in processed foods. The results obtained will allow the development of targeted sampling plans for certain food products as is currently being done for fish products.
