Title: Bacillus cereus spores in Repackaged Milk Powder at Khartoum State, Sudan - 2016
Author: Magzoub, Taiseer Bala Ahmed
Abstract: Background: Spore forming bacteria that contaminate foods are a real problem to food hygiene and safety, because the spores are resistant to heat, freezing, chemicals and adverse environmental conditions. One of these bacteria Bacillus cereus which can cause food spoilage or some species causes food-borne illnesses. This study was designed to detect contamination of repackaged milk powder with bacillus cereus spores, and to study awareness of handlers about repackaged milk powder contamination. Methodology: This is a descriptive cross sectional laboratory base study conducted during November, 2016 in Khartoum State. Twenty two samples were taken from every one of the three selected processing plants in Khartoum, Um-dorman and Bahry Localities. The total number of samples of the three processing plants was 66 samples. For every sample taken from a processing plant another sample was taken from groceries of the same plant logo for comparative reasons. The total number of samples investigated then equal 132. Those samples were hygienically collected and microbiologically tested at the Faculty of Public and Environmental Health in Food Hygiene and Safety laboratory for prevalence bacillus cereus spore and using conventional microbiological biochemical test to confirm results. One hundred questionnaires were filled by randomly chosen participants to know the public health awareness about milk powder contamination. Data from questionnaire was analyzed using Statistical Program for Social Studies (SPSS-16). Results: The study showed that the 132 (100%) samples were contaminated with different bacterial species. Spores of bacillus cereus were found in high level in repackaged milk powder 8(6.06%). The contamination with bacillus cereus spore in opened sacks at groceries was 9.09% (n=6) higher than in the closed ones in the same processing plants, was 3.03% (n=2). The contamination of samples was attributed to poor storage and poor handling in groceries. The processing plants were not applying food safety guideline during repackaging milk powder. Only 12% of participants only had knowledge about contamination milk powder. Conclusion: Repackaged milk powder was found contaminated with Spore of bacillus cereus. The study recommends that all processing plants should apply Good Manufacturing Practice (GMP) and Good Personal Hygiene (GPH). Public awareness should be enhanced about food hygiene.
