Abstract:

The aim of this study was to detect the safety of two foods (Shawerma and ice cream ) usually sold in streets of Khartoum State. They were collected from different sources (Albait Alssory-Khartoum North, College of Agricultural Studies - Sudan University of Science and Technology, Omdurman maket, Almazallt, Freeway Factory and household). Total Bacterial Count (TBC) (cfu/g) in Shawerma was found to be 5.3103, 8.4103 and 5.3104 in Albait Alssory, Collage and Omdurman market, respectively. Coliforms count (cfu/g) was found to be nil, 1.710 and 2.610 in Albait Alssory, College and Omdurman market, respectively. The samples of College were found to be highly contaminated by TBC and moulds and yeasts compared to other two sources. On the other hand Omdurman samples were found to be highly contaminated with coliforms.With regard to pathogenic bacteria they were highly contaminating Shawerma of Omdurman Market, while Shawerma of Albait Alssory was of the least contamination by the pathogenic bacteria. TBC of ice cream was 5.9104, 3.6103 and 5.9104 in factory, Almazallat and household, respectively. Moulds and yeasts were not detected in Almazallat and household ice cream, while they were 4.3102 in the factory. However, Almazallat and Factory ice cream were free of E. coli, Salmonella<.em> and Staph.aureus. Household was free of E. coli but with Salmonela and Staph. aureus .The Pb l (ppb) in Shawerma of Albait Alssory was 24.84 and 2.90 in College and not detected in Omdurman market. The Pb in ice cream was 5.10, 8.32 and.0.26 in Almazallat , factory and household, respectively. The Al (ppm) in Shawerma of Albait Alssory, College, and Omdurman market was 1.37, <0.30 and 1.75, respectively. The Al was 3.5, <0.30 and <0.30 in Almazallat, factory and household, respectively. The peroxide value (%) in Shawerma was not detected in Albait Alssory and College but10.0 in Omdorman market samples, while it was 4.0 in ice cream samples. Interactions between authorities and consumers are needed to avoid harms possibility from street foods.
