Abstract

Introduction: Milk is an important part of human nutrition in different ages. Thus, hygiene and control of the milk during processing, transportation, saving and marketing is of uital significance.Methods & Methods: This cross-sectional study was performed to consider any to microbial contaminations in RAW MILK during 1999-2003. Totally, 780 samples were selected from the farms and market using a multi- stage categorical sampling. For primary isolation of E.coli and S.aureus, EMB agar and Chapman medium were used respectively. The data was saved in SPSS software and analyzed by t.test. Findings: 63 samples (19.7%), of all the 320 samples taken during milking, were contaminated with both E.coli and S.aureus, 62 samples (19.3%) and 30 samples (9.3%) were contaminated with only E.coli, and S.aureus, respectively. Also, 165 samples (51.6%) were not contaminated by the two mentioned organisms. During transportation, 200 samples were collected of which 98 samples (49%) were infected with both E.coli and S.aureus were isolated, also in 15 samples (7.5%) and 30 samples (% 15), E.coli and S.aureus seen, respectively. In transportation phase, 57 samples (28.5%) were not contaminated with these organisms. In marketing center, 260 samples were taken of which 152 samples (58.4%) were contaminated with both E.coli and S.aureus, and 28 samples (10.8%) and 72 samples (27%) were contaminated with only E.coli and S.aureus respectively. So, in this phase in 8 samples (3.1%) no contamination with the organisms was proved. Conclusion: According to the results in each stage, microbial contaminations were significantly different (P<0.05). The contamination rate by E.coli and S.aureus increased significantly during the time between the milking stage and market distributions.
