During 2004 120 milk samples have been analyzed, which were taken from two different factories in Tirana (Albania). Out of these, 60 samples are unpasteurized milk, the other 60 samples are taken from the same milk, after the process of pasteurization. These samples have been analyzed for the presence of Escherichia coli as a bacterial contamination indicator, which can be dangerous for the consumers' health. The presence of Escherichia coli was identified in 4 cases out of which 3 were unpasteurized milk samples (5% of unpasteurized milk samples or 2.5% of all samples). While 1 sample was part of pasteurized milk which represents 1.6% of pasterized milk samples or 0.8% of the total. The above results are real indicators for the presence of the bacterial contamination in unpasterized and pasteurized milk. It is evident that this study is a proof that indicates every deviation from pasteurization technology (represents a real risk for milk consumers when the binomial temperature time is not respected).
