PFAS on our plate: The critical need for stronger food regulation and testing

Potentially unsafe levels of per- and polyfluorinated substances (PFAS) in food and drink have become a major global concern. LGC Standards examines the scale and severity of PFAS contamination in food in light of recent toxicology data, evaluates global regulatory progress, and considers expert opinions on the necessary steps to enhance clarity for the food industry and better safeguard public health. The impact of advancements in sample processing and analytical techniques such as liquid chromatography (LC), gas chromatography (GC), mass spectrometry (MS), high resolution mass spectrometry (HRMS), and nuclear magnetic resonance (NMR) for detecting and quantifying trace levels of PFAS across various food and packaging matrices is also reviewed.
