Microbiological Quality of Milk Powder Packed in Sudan and Their Antibiotic Susceptibility |Biomedgrid

In this study the microbiological quality of milk powders packed in Sudan has evaluated by method of enumeration of total viable bacteria, coli form, Escherichia coli and Staphylococcus aureus. Then the antibiotic susceptibility of pattern bacterial isolates has been assessed. Eight samples of different brands packed in Sudan have collected. The highest total bacterial count (5.3×103cfu/ml) was found in sample no-8, and the lowest one 3.4×102cfu/ml in sample no-4, but they were found free from all other microbes which were tested. Some pathogenic bacteria were isolated from the samples. Bacillus spp, was the most prevalent isolate (46.2%) followed by Streptococcus spp. (30.8%), Micrococcus spp. (15.4%) and Staphylococcus aureus (7.7%). All bacterial isolates were found susceptible to Cefuroxime and Ceftriaxone, but they were resistant to Nalidixic acid, Cotrimoxazole and ampicillin. The practice of packing milk powders should discourage as the final products contaminated with consequent public health risk.
