Microbial Load of Pasteurized Milk Produced In Khartoum State

This study was to investigate the range of contamination of pasteurized milk samples which were marketed in Khartoum State shops, and identification of different types of bacteria present in collected milk from various factories. Sixty packaged pasteurized milk samples were collected. The samples were examined microscopically and cultured to determine if there were bacteria, and types of bacteria involved in milk samples were determined. Twenty one (21) 35% of milk samples were found to be positive for presence of bacteria where as (39) sample were negative for bacteria. The isolated bacteria from pasteurized milk were enterobacter 42.8%, proteus mirbilis 9.5%, pseudomonas aroginosa 14.2%, bacillus creus 23.2%and actinobacillus lignersii 9.5%. The present study concluded that that pasteurized milk which was distributed in Khartoum State was of low quality. Hence it was recommended that quality assurance program should be started to ensure that good quality milk and milk products are produced and consumed in the country.

أجريت هذه الدراسة لمعرفة وجود البكتريا ومعرفة الأنواع الملوثه للألبان المبسترة بأسواق ولاية الخرطوم. جمعت سـتون عينه من اللبن المبسـتر من بقالات بولاية الخرطوم وفحصت مجهرياً بعد أن زرعت لمعرفة أنواع البكتريا الموجودة فيه من جملة تلك العينات. احدي وعشرون عينة من 35% وجد بها نمو بكتيري ، بينما لم تنمو في 39 عينة من اللبن المبستر65% كمـا وجـد خلـو بعض أنـواع اللبن من البكتريـا. ومن أنـواع البكتريا المعزولة. Enterobacter, Proteus, Pseudomonas bacillus, Actinobacillus. خلصت النتائـج إلي تـدني جـودة اللبن المبستر المنتج والـذي يسـوق بولايـة الخرطوم. لـذا توصي الدراسة بوضع برنامج لصحة وجـودة ومراقبة اللبن المنتج للمستهلك. وتوضح بداية الإنتاج والاستهلاك لضمان سلامتها.
