ASSESSMENT OF PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) IN CONSUMER FOOD PACKAGING
Stroski, K. and Y. Sapozhnikova. | Chemosphere 395:144824(2026)

A new method was developed and validated to analyze 73 PFAS from 15 different classes in paper and plastic food contact materials (FCMs) based on methanolic extraction and liquid chromatography-mass spectrometry (LC-MS/MS) analysis. The method was validated at three spiking levels with five replicates per level. Acceptable recoveries and repeatability were achieved for 96-100% of analytes between various spiking levels and food packaging materials. The validated method was used to test 66 paper and plastic food packaging materials in direct contact with the previously tested food samples of chicken, pork, beef, and catfish purchased from grocery stores in the U.S. Nine PFAS were detected in the samples: 8:2 FTSA, 6:2 diPAP, 8:2 diPAP, diSAmPAP, PFBA, PFHxA, PFOA, PFBS, and PFOS with ∑PFAS concentrations ranging from 0.11 to 16.3 ng/g. At least one PFAS was detected in 64% of the samples. The most frequently detected PFAS was 6:2 diPAP found in 61% of samples, across all material types in concentrations of 0.09-10.3 ng/g. Results suggest no evidence of PFAS transfer from FCMs tested in this study to packaged food tested in a previous study.
