Abstract
Small and medium enterprises are important for economic growth not only in Tanzania but
all over the world. Most of them are informal, without official registration. However, they provide
tremendous contribution to food security, nutrition, income generation and poverty reduction in
the country. Therefore, upgrading and modernization of Small and Medium Enterprises (SMEs)
to ensure food security, safety and quality of food has becomes one of the priorities of Tanzania
development visions of 2025, which is the blueprint of structural economic transformation of the
country. To help achieve this, the present study was conducted to assess the safety of cultured
milk. A total of 33 cultured milk samples were collected from 11 SMEs which were analyzed in
triplicate to make 99. Two microorganisms, Escherichia coli and Staphylococcus aureus were
analysed in cultured milk. Results were compared against the existing Tanzania standards. The
isolates had an overall mean of 2.02 × 102 ± 1.73 × 102CFU/g, 1.91×102 ± 1.85 ×102CFU/g
respectively for E. coli and S. aureusc count. The results obtained were higher than the limits set by
the Tanzanian Standard (TZS1625:2013). It may thus be concluded that sampled cultured milk was
of poor microbial quality and hence not safe for consumption. Poor hygienic practices during milk
handling pose a high risk to cultured milk and render it unsafe for human consumption.
