Cesium-137 (137Cs) is an alkali metal radioactive isotope of cesium, which is mainly formed as by-product of uranium nuclear fission, especially in nuclear fission reactors. 137Cs can be usually found in the environment due to anthropogenic contaminations. In Europe, however, it mainly occurs as a result of the Chernobyl accident fallout. Due to ra...
Conference Paper
The need for data on the organoleptic and safety qualities of wild game meat derives from the will to promote this food as a valid nutritional resource. In this perspective, hunting periods could be scheduled not only taking into account the biology and the ecology of the game species, but also the conditions ensuring the best sensory profile of ga...
Chapter
Assuring hygiene and quality of hunted game meat is relevant for public health, and should therefore be undertaken before game meat is marketed. Standardisation of the analytical methods and specific microbiological thresholds should be implemented, also considering the remarkable diversity in hunting traditions, conditions and facilities.
