European inter-comparison studies as a tool for perfecting irradiated food detection methods

Abstract In this paper, we present the results of inter-comparison studies on identification irradiated food carried out by leading European laboratories from 1991 to 2018. 1990s, Federal Institute for Health Protection Consumers and Veterinary Medicine in Germany played role organization inter-laboratory tests subject. At beginning century, Spanish Agency Food Safety Nutrition National Centre took over role. total, 47 international were which nearly 500 samples alimentary products analysed 37 14 countries. The aimed at proving reliability analytical methods – thermoluminescence (TL), photostimulated luminescence (PSL), electron paramagnetic resonance (EPR) spectroscopy specific control skills experience participating laboratories. made possible a discussion why some are more difficult identification. general, showed that TL measurements such as herbs, nuts, peppers, raisins, EPR fish chicken bones, fresh strawberries, dried fruits could be used reliable methods. challenge facing now, is related complex diet supplements or biopharmaceuticals, only additives irradiated.
