The objective of the study was to achieve the best food chain coverage with a restricted number of samples (n = 496). The geographic distribution, different market chains and labels, and consumption frequencies were taken into account in the construction of the sampling plan. Weighting factors such as contamination levels, consumption frequency and the diversity of food items were applied to set up the model. The very low detection capabilities (CC(beta)) of the analytical methods used (sub-ppb) allowed reporting of 78.2% of the overall dataset above CC(beta) and, in particular, 96.7% for the baby food category. The highest furan levels were found in powdered roasted bean coffee (1912 microg kg(-1)) with a mean of 756 microg kg(-1) for this category. Prepared meat, pasta and rice, breakfast cereals, soups, and baby food also showed high mean furan contents ranging from 16 to 43 microg kg(-1). Comparisons with contamination surveys carried out in other countries pointed out differences for the same food group and therefore contamination levels are related to the geographical origin of food items.
