Abstract EN
Milk in Tanzania has been reported to be contaminated with large number of bacteria.
This is because (1) milk is obtained from animals with unknown health status, (2) good milking and handling practices are to a large extent not observed, and (3) marketing and distribution are done in informal channels.
These factors are potential causes of milk-borne diseases and milk quality loss.
The aim of this study was to assess nutritional risks in milk as reported in literature over a period of 20 years and through analyses of samples collected during the present study.
The issues highlighted in literature were high bacteria and coliform counts exceeding standard levels in East Africa, prevalence of bacteria and drug residues in milk, and adulteration.
Based on performed analyses, total bacterial count 1.0×107 colony forming units per millilitre (cfu/ml) and total coliform count 1.1×107 cfu/ml, also greater than recommended levels, were found.
Ten bacteria types were isolated from milk samples (five, Pseudomonas aeruginosa, Listeria monocytogenes, Listeria innocua, Listeria ivanovii, and Klebsiella spp.
are reported in Tanzanian for the first time).
Two drugs tetracycline and sulphur were detected.
Therefore, it is worth noting that integrated research is needed to evaluate the situation and address these challenges.
