Abstract

Objective: To determination of contamination levels of some microbial agents in dairy products for pregnant women in some provinces/cities, 2020-2021. Subjects and methods: cross-sectional descriptive study, sampling and testing 4 common microbiological criteria of 1,500 samples of dairy products circulating in 6 major cities/provinces. The results were compared with Decision No. 46/2007/QD-BYT, 19/12/2007 of the Minister of Health. Results: Dairy products for pregnant women circulating in 6 provinces/cities with the highest risk of contamination are cheese, milk fat and fermented milk. The most commonly infected bacteria is Listeria monocytogenes. In which, 6.00% of cheese samples, 5.0% of cream samples were contaminated with E.coli. There were 2.22% of Cream powder samples contaminated with Staphylococus aureus; 5.56% of milk powder samples, 3.0% of cheese samples contaminated with Salmonella; There were 3.33% of butter and milk fat samples, 10.00% of fermented milk samples contaminated with Listeria monocytogenes. Conclusion: Contamination of E.coli, Staphylococus aureus, Salmonella and Listeria monocytogenes still occurs in some milk and dairy products intended for pregnant women, posing a risk of food poisoning for pregnant women.
