Food safety is currently one of the most important challenges confronting consumer, producers, and distributors. It is also an issue that is in the centre of interest of scientists and experts because it has great health, economic, and legal consequences. Frequent dramatic food emergencies occurred in Europe focus the attention on food safety in order to manage the risks for human health that could occur in any point of the food chain. Increased environmental pollution, rapid expansion in international trade of food and in tourism sector have resulted in increased risk of higher intake of food chemical contaminants through diet and detrimental health effects. Furthermore, the issue of emerging pollutants has risen to the forefront of the food safety area within the past decade. Emerging contaminants are previously unknown or unrecognized pollutants. Most of them have been present in the environment for a long time, but their significance and presence are only now being elucidated and, therefore, here is a need for reliable data on their occurrence in food in order to perform a valid quantitative risk assessment of human exposure. Food safety is a global challenge, too large to be met by countries acting alone.
