To determine the prevalence of pathogenic bacteria in street vended ready-to-eat meats in Windhoek, Namibia, a total of 96 street vended ready to eat meat samples were evaluated. Prevalences of 42%, 52%, 15%, 6% and 83% were observed for Escherichia coli, Staphylococcus aureus, Listeria monocytogenes, Shigella and Enterobacteriaceae respectively, while the highest aerobic plate counts were 7.74 Log cfu/g, 5.67 Log cfu/g, 5.12 Log cfu/g 4.56 Log cfu/g, 3.3 Log cfu/g, 5.75 Log cfu/g respectively. Unsatisfactory microbial levels were 32% for aerobic plate count, 26% for Enterobacteriaceae, 35% for Escherichia coli, 11% for Listeria monocytogenes, 7% for Staphylococcus aureus and 6% for Shigella. Salmonella was detected in 11% and 40% of samples from two suburbs. The unsatisfactory microbiological quality of some ready-to-eat meats necessitates the provision of training on food safety and hygiene to street vendors for consumer protection.
为了确定纳米比亚温得和克街头出售的即食肉类中病原菌的流行情况，对 96 份街头出售的即食肉类样本进行了评估。分别观察到大肠杆菌、金黄色葡萄球菌、单核细胞增生李斯特菌、志贺氏菌和肠杆菌科的流行率为 42%、52%、15%、6%和 83%，而最高的需氧平板计数分别为 7.74 Log cfu/g、5.67 Log cfu/g、5.12 Log cfu/g、4.56 Log cfu/g、3.3 Log cfu/g 和 5.75 Log cfu/g。需氧平板计数、肠杆菌科、大肠杆菌、单核细胞增生李斯特菌、金黄色葡萄球菌和志贺氏菌的微生物水平不满意率分别为 32%、26%、35%、11%、7%和 6%。从两个郊区的 11%和 40%的样本中检测到了沙门氏菌。一些即食肉类的微生物质量不理想，需要为街头小贩提供食品安全和卫生培训，以保护消费者。
