Emerging Toxins in Food and Feed

Despite huge research investments on mycotoxins and other toxic secondary metabolites of fungi and plants, prevention, control and proper exposure assessment remain difficult and agricultural and food industry continue to be vulnerable to problems of contamination. In the last few years, “mycotoxin analysis” has continuously developed from the targeted analysis of individual mycotoxins to metabolite profiling and metabolomics of (ideally) all secondary metabolites that are present in food crops and which are involved in plant-fungus interactions. High performance liquid chromatography- tandem mass spectrometric LC (HR)MS(/MS) methods have led to unexpected occurrence data on the presence of so-called emerging mycotoxins including novel and conjugated (masked) mycotoxins, as e.g. the glutathione-mediated detoxification products of the Fusarium toxin deoxynivalenol.
