Resumo: In this study, the data of foodstuffs samples collected at retail and subjected to analytical determinations, in the period of 2008 to 2010, under the National Sampling Plan (NSP) by ASAE –The Portuguese Authority for Safety Food and Economic, were analyzed. The main objective of the study was to evaluate the microbiological data in the NSP report and to identify the source of the non conformities, checking the development of the foodstuff groups with higher susceptibility to contamination by microbiological hazards. During the mentioned period 5541 samples were collected among various groups of foodstuffs and the data from 1966 samples submitted to microbiological analysis were studied. The total non conformities of NSP increased from 3.4 % to 6.9 % and in 2010 around a third were of microbiological origin. The microbiological non conformities were detected in 3.8 % (2008), 3.6 % (2009) and 5.4 % (2010) of the samples analyzed and mainly observed in meat and meat products, milk and milk-based products. The largest number of non conformities samples in the group of meat and meat products was due to the presence of Salmonella, whereas in the group of milk and milk-based products this was due to the presence of L. monocytogenes
