عنوان انگلیسی Microbial Quality of Ready-to-Eat Street Vended Food Groups Sold in the Johannesburg Metropolis, South Africa
چکیده انگلیسی مقاله Background: In many developing countries, the risk of contracting a food-borne disease is high after consuming contaminated ready-to-eat Street-Vended Foods (SVFs). The main objective of this research was to assess the microbiological quality of SVF groups sold in the Johannesburg Metropolis, South Africa. Methods: A stratified random sampling procedure was used for collecting the ready-to-eat SVF samples. Methods prescribed by the International Organization for Standardization (ISO) were used for analyses for aerobic colony count, Enterobacteriaceae count, presence of Escherichia coli O15:H7, detection of Salmonella, Staphylococcus aureus, and Listeria monocytogenes. The bacterial isolates were identified by 16S rRNA gene sequencing. Data analysis was done using IBM SPSS Statistics V25.0. Results: Of the 205 ready-to-eat SVF samples, 85.37% had aerobic growth. The vast majority (78.18%) of the 110 ready-to-eat SVF samples had Enterobacteriaceae growth. From the 110 SVF samples, the prevalence rates of L. monocytogenes, S. aureus, Salmonella spp., and E. coli O15:H7 were 46.36, 31.8, 21.8, and 1.8%, respectively. There was no statistical significant difference (p>0.05) in the prevalence rates of L. monocytogenes, S. aureus, Salmonella spp., and E. coli O15:H7 in the various SVF groups. Conclusion: Based on the findings of this study, the microbial quality and safety of ready-to-eat SVFs sold in the Johannesburg Metropolis remain a serious public health concern. Hence, it is necessary to educate street food vendors and enforce food safety legislation in the street food sector in the country. DOI: 10.18502/jfqhc.7.1.2448
