Back-tracing Poultry Meat Chain Exposure to Rapidly Metabolized Pollutants Using Volatile Compound Metabolic Signatures in Liver Tissues
It is well established that food-producing animals are exposed to toxic micropollutants via environment and feeds, and that micropollutants entering the animals are transferred to edible tissues, thus representing a chemical human health hazard.

Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
FDA Talks to LCGC About Chromatographic Techniques for PFAS Detection in Food Supply
December 5th 2023A new study details the US Food and Drug Administration (FDA)’s recent expansion to 30 analytes, from a previous 16, in the method for determining per- and polyfluoroalkyl substances (PFAS) in the US food supply, which, in turn, may mean that additional analytes may still yet be identified (1).
