Bangladesh Journal of Microbiology , 2017, DOI: https://doi.org/10.3329/bjm.v34i1.39603

Abstract: Foodborne pathogens are affecting public health globally. Street foods being an important part in daily life of urban people are considered as a major source of foodborne pathogens. The major sources of street food contamination are water and the unhygienic condition of the vendors and food preparing places. This study was carried out to assess the load of antibiotic resistant enteric bacteria in the hands of street food vendors. A total of 20 street food vendors were selected from various locations in the Dhaka University campus and their hands were rinsed with 500 mL normal saline. Most of the samples contained high total viable counts, total coliforms count and total fecal coliforms count. A total of 25 selective colonies were identified as enteric bacteria including E. coli, Klebsiella spp. and Acinetobacter spp. by biochemical tests and 16S rDNA sequencing. All these isolates showed high antibacterial resistance against Amoxacilin (64%) and most of them showed sensitivity against Ciprofloxacin (76%) and Azithromycin (72%). This study revealed that the hand hygiene of street vendors is very poor and may have serious implications for public health due to possible contamination of food. This study, therefore, suggests proper training and education of street food vendors in order to improve their knowledge of personal hygiene and sanitation.

Street Food around the World: A Review of the Literature [PDF]
Kouamé Guy Marcel Bouafou, Gnakon Flora Carenne Beugré, Yao Célestin Amani
Journal of Service Science and Management (JSSM) , 2021, DOI: 10.4236/jssm.2021.146035

Abstract: This review aims to analyze the various studies dealing with street food. It is also called “street catering”, “the informal food sector”, “eating out”, “popular catering” or “food outside the home”… The persistence of street food is explained by rapid urbanization and the multiple constraints associated with it: distance between workplaces and home, poverty, lack of transport and canteens in the workplace. This sector provides jobs and allows the poor to eat more cheaply. Consumers of street foods are children, pupils, students, the unemployed, workers, men and women. Street food is sold by women and men, sometimes by children. Street food offers a wide range of foods, with different names, depending on the country. There are breakfast foods based on bread or sandwiches, cereal porridge, donuts, cookies, pastries, dairy products… Then there are the main dishes for lunch or dinner, which are often the traditional foods of family menus, grilled meats and industrial foods. Fruits and vegetables are also sold on the street. In the streets, traditional drinks are more popular than industrial drinks. Street foods are high in fat, carbohydrates and therefore very energetic. The street food sector accounts for 2% - 10% of jobs in the agricultural economy. Street meals are cheaper (US $0.1 - US $3) and sometimes account for more than 30% of household food expenditure. The evaluation of good handling practices and the microbial quality of street foods reveals that these foods present risks to the health of consumers and constitute a public health problem. In addition, the use of non-biodegradable plastic packaging for the sale of street food has negative health and environmental consequences. Globally, the street food sector is not regulated. This requires the establishment of control structures to clean up this sector and curb potential health and environmental hazards.

Demba Dembele, Mamadou Wele, Bawa Boya, Haziz Sina, Basile Boni Saka Konmy, Adolphe Adjanohoun, Lamine Baba-Moussa
Food and Nutrition Sciences (FNS) , 2024, DOI: 10.4236/fns.2024.153012

Abstract: The World Health Organization states that foodborne diseases are a worldwide public health issue. Although street foods can provide nutritious and affordable ready-to-eat meals for city dwellers, their health risks can outweigh the benefits. A cross-sectional study was conducted in the Bamako district, focusing on street food vendors near schools, universities, extensive markets, administrative centers, and major roads. We aimed to sample fifty (50) sellers per municipality, making 300 sellers for the Bamako district. We developed a survey sheet to collect data, and six teams rotated between the municipalities each month. Before starting the collection, the teams were provided administrative papers approved by the municipal authority. The survey revealed three types of sales sites: fixed (65%), semi-fixed (30%), and mobile (4.40%). The proportion of sellers was 26.8%, 23.2%, 19.7%, and 4.2% in municipalities III, IV, and I. In municipalities I, II, III, IV, and VI, respectively, 92%, 95.70%, 93%, 87.2%, and 100% of the sellers were female. The age distribution of sellers was 65.63%, 46.81%, 40.82%, 38.30%, 36.17%, 36%, and 32% in the 25-34 and 35 - 44 age groups. Illiteracy rates were 59.20%, 61.70%, 55.30%, 75%, and 56% in municipalities I, II, III, IV, and VI, respectively. The study identified two categories of sellers: 48.3% in type 1 and 51.7% in type 2. The first category comprised 154 sellers, and the second 165 sellers. The survey found that 66.00%, 56.00%, 48.90%, 44.90%, 38.30%, and 34.40% of municipal V, VI, III, I, II, and IV sales sites were open-air. In municipality I, 63.30% of the sites were under hangars, while in municipalities II and IV, the corresponding percentages were 51.10% and 59.40%, respectively. Moreover, 46.00%, 31.90%, 31.30%, 30.60%, and 27.70% of the sites in municipalities VI, II, IV, I, and III were located next to gutters. In conclusion, this study identified several factors that could compromise the quality of street foods sold in the six municipalities of Bamako.

Microbial Quality of “Tchachanga”, a Barbecued Mutton Sold in Benin [PDF]
Kadoéito Cyrille Boko, Martial Gangnito, Soumanou S. Toleba, Philippe Sessou, Ulbad Polycarpe Tougan, Oscar Nestor Aguidissou, Marc T. Kpodekon, Soua？bou Farougou
Advances in Microbiology (AiM) , 2017, DOI: 10.4236/aim.2017.78049

Abstract: The microbial quality of Tchachanga, a barbecued mutton sold at Bohicon and Hilla-Condji bus stations in Benin was assessed in accordance with French standards (DGAL, 2000). The analyses revealed that the average total viable counts (TVC) recorded in Bohicon (3.96 × 10⁸ cfu/g) and Hilla-Condji (5.51 × 10⁸ cfu/g) exceeded standard safety limits (3 × 10⁵ cfu/g). Similar observations were made for other parameters such as fecal coliforms count, Escherichia coli count, sulphite-reducing anaerobes, Staphylococcus aureus, yeasts and molds. Salmonella sp were absent in all samples. There was no significant difference (P > 0.05) between the microbial loads obtained in Bohicon and Hilla-Condji. This study shows that barbecued mutton sold in these two stations is unsafe for human consumption. It is therefore important for food safety authorities in Benin to take appropriate measures and sensitize sellers on strict observance of hygiene rules in order to preserve public health.

Joyce Afua Sarpong Haleegoah, Kofi Osei Akuoko, Peter Dwumah, Kofi Amoako Marfo, John Boulard Forkuor, Benedicta Nsiah Frimpong, Lydia Brobbey
Advances in Applied Sociology (AASoci) , 2020, DOI: 10.4236/aasoci.2020.1011025

Abstract: Street foods play an important role in the lives of urban residents in developing countries. Consequently, there has been a lot of research into the nutritional quality of street vended foods, and the safety and hygiene of these foods. Researchers in Ghana have focused not only on the safety and hygiene of street foods but also on the effectiveness of regulations of these foods. While these provide important knowledge base for policy and action, very little has been done on challenges to improve the quality of local street vended foods. This study presents qualitative data from key stakeholders (vendors, consumers, regulators), on the challenges and opportunities to improve the quality of street vended local foods. Results show several challenges that relate to the safety and hygienic conditions at preparation and sale environments, and issues with the local regulatory authorities, inadequate capital with its related challenges and insecure space for street food vendors. This research recommends that efficient and effective collaboration between all actors and relevant institutions could offer the vendors an opportunity and capacity to provide healthy, affordable and preferred local dishes of cultural value to consumers.

Financial Innovation for Survival among Micro-Enterprises with Declining Profit Margins [PDF]
Paddy Mugambe
Open Journal of Business and Management (OJBM) , 2024, DOI: 10.4236/ojbm.2024.125159

Abstract: Micro enterprises are faced with the daunting task of having to survive after being established by individuals who may know little or nothing about planning in a formal way. These firms face challenges due to the limited planning knowledge and the pressure for quick profitability by those who establish them. This paper explores how financial innovation affects survival of micro-enterprises within an intensively competitive environment and declining profit margins. A case study approach was initially used focusing on five micro-enterprises within Kampala City selected from the five divisions of the City. However, after analyzing the collected data, a cross-sectional design was found appropriate and accordingly adopted. Key findings reveal that micro-enterprises succeed through product variation, efficient supply chain management, competitive pricing for standard products, and premium pricing for nonstandard products. These strategies enable them to stay relevant and profitable amidst intense competition and declining profit margins. The findings from the study indicate that there is a significant relationship between product innovation, cost saving innovation and survival of micro enterprises. However, it is only product innovation that has a significant effect on micro enterprise survival. Qualitative results of the study also indicate that micro enterprises operate within a largely unregulated environment. The results of the study have significant value to practitioners especially the policy makers who should take an interest in generating policies that support the survival of micro enterprises, given the critical contribution they make to the economy.

Electrolytic Cobalt Removal in Wastewater [PDF]
Isabela O. Santos, Isaque C. A. Santos, Leandro V. Pontual, Luciane P. C. Monteiro, Fernando B. Mainier
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.75065

Abstract:

Industrial effluents containing cobalt ions have become a serious problem for the environment, unless properly treated, due to their toxic potential. Currently there has been an intensification of the use of cobalt in several industrial sectors as super alloys, catalysts, batteries and pigments in ceramic materials, and a consequent intensification also of environmental contamination. This paper aims to show a simple and effective treatment for the removal of cobalt ions from simulated industrial wastewater, based on cathodic eletrolytic removal using a carbon steel screen. As a result, a 73% removal of cobalt ions from solutions was achieved with a concentration of 400 mg Co²⁺/L, a current of 0.30 A and a voltage of 30 V. In the same conditions, 84% and 88% was removed from 200 mg Co²⁺/L and 100 mg Co²⁺/L, respectively. Thus, this method presents itself as a cheap and efficient alternative for the treatment of industrial effluents containing cobalt ions.
