Abstract

Nowadays, the food safety and the related health risks for humans are a major issue. It has become a priority to ensure the health and well-being of the population through the better scientific understanding of the food intake influence. A frequently found harmful feature of human diet is the simultaneous presence in food stuff of both essential and toxic elements. A significant example of this situation is represented by horse meat. The aim of this survey is to evaluate the elemental content of muscular, hepatic and renal tissues of horses bred in different countries of the East of Europe and slaughtered in Italy. The studied population consisted of about 100 individuals; the sampling period, coinciding with the highest market request, was extended from November to March. Freeze dried tissues were pelletized and carbon coated prior to analysis. The samples were analyzed using Particle Induced X-ray Emission (PIXE) technique at the AN2000 van de Graaff accelerator of the INFN-National Laboratories of Legnaro. The accuracy of the results was verified using certified standard reference materials prepared and measured in the same experimental conditions.
