Food hygiene and safety practices of food vendors at a University of Technology in Durban

Khuluse, Dawn Sihle January 2016 (has links)
Submitted in fulfilment of the requirements of the Masters Degree of Applied Science in Food and Nutrition, Durban University of Technology, Durban, South Africa, 2016. / Introduction: Food vending is becoming a very important and a useful service. Moreover, socioeconomic factors and lifestyle changes forces customers to buy food from street vendors. Since the food industry is growing worldwide, good hygiene practices coupled with food safety standards is of vital importance. Currently there is inadequate information or scientific data on the microbiological quality and safety of vended foods in South Africa more especially in Durban. To date limited research has been conducted on the food handlers (FH’s) operating as food vendors in different areas of Durban, and a lack of documented evidence about the knowledge that food vendors have on food safety and food hygiene has resulted in the interest in this research. Aim: The aim of this study was to ascertain food hygiene practices and knowledge, food safety practices and the nutritional value of the food served by various food vendors at DUT in Durban. Method: A total number of 15 food vending stalls (comprising of 15 managers and 39 food handlers) situated within the Durban University of Technology (DUT) Durban campuses participated in the study. The study was conducted on all food vendors who prepared and served food items on site. Data collected was of a quantitative nature with two sets of questionnaires (Managers questionnaires and (FH’s) questionnaires), observation sheets to observe FH’s during food preparation and cleanliness, and weighing and recording of menu items prepared and served in order to determine portion sizes and the nutritional content. All the administration of data was completed by the researcher on a Microsoft Excel spread sheet and analysed on the SPSS software version 20. Recording and weighing of menu items was done using an electronic food portion scale. A statistician was consulted to assist in the interpretation of the data. Results: The majority (66.67%) of vendors were females with the educational level that was fairly high, (73.33%) had secondary education. Most of the respondents (80.00%) had been in the food vending business for more than 3 years. The availability of proper infrastructure was poor, 40.00% of the vendors obtained running water from the kitchen taps within the stalls and 60.00% obtained water from a communal sink tap outside the food stalls. Most vending stalls 66.67% had no proper storage facilities; perishable stock was stored on refrigerators, while non-perishable food items were stored on built-in shelves, on top of fridges, on the floor, in storage containers, and on tables due to shortage of space. Thirty three percent of the vendors had designated storerooms for non – perishable items. Food preparation and cooking space was very minimal as a result the researcher observed that in some stalls white and red meat was grilled in the same griller and that increases the chances of cross-contamination. The researcher also observed that the area where most of the vending stalls were situated had no shelter and paving, as a result during food preparation and service, food was exposed to dust, air pollution and flying insects. Most managers 73.33% and FH’s 56.41% attended hygiene and food safety training but observational findings indicated that important hygiene practises such as washing of hands before serving food were not practised. Another concerning observation regarding personal hygiene was that students did not wash hands prior to eating food despite the availability of tap water within the dining area. The majority of managers had contracts with suppliers, and grocery items were mainly purchased from wholesale stores, meat items from formal retailers. A large number of managers 73.33% bought and delivered perishable products themselves using own cars, while 13.33% used refrigerated trucks from the suppliers for the delivery of perishable goods. In that way delivery temperature of food items was not monitored and maintained. The nutritional value of food served by vendors was imbalanced with the majority of the meals exceeding the recommended energy contribution from fat of 15–30%, the carbohydrates (CHO) contribution was lesser than the stipulated percentage of 55-75%, and the mean energy contribution of protein was within the recommended percentage of 10-15%. The mean energy contribution made by fat in all meals was higher than the recommended percentage 15-30%, with the highest contribution of 63.59% and the lowest of 34.12%. High fat meals were of great concern as prospects of cholesterol, high blood pressure and heart diseases were high. The CHO content of meals was below the stipulated percentage of 55- 75% with the maximum percentage of 49.86% and the minimum of 31.04%. The mean energy contribution of protein was 15.36% which was generally within the recommended percentage of 10- 15%. Furthermore, the study revealed that out of the 12 881 kJ recommended for men and 10 093 kJ for females; male students on an average were consuming approximately 14% more kJ than recommended, and female students were consuming approximately 27% more kJ than recommended from the meals. Frequent consumption of such high energy meals can lead to overweight and obesity among young adults. Conclusion: The results of the study revealed the urgent need for basic infrastructure such as a decent food kiosk with adequate working space, proper washing and storage facilities to improve food safety and hygienic practices. Even though food vendors claimed to have received hygiene training, knowledge attained was not effectively practiced or demonstrated; and that placed students at risk of foodborne illnesses. Furthermore, the nutritional value of food served by vendors was imbalanced with the majority of the meals exceeding the recommended energy contribution from fat of 15–30% and the CHO contribution being lesser than the stipulated percentage of 55-75%. Recommendations: Extensive training programme and regular supervision should be put in place by management of the Institution to ensure that proper hygiene practices are in place and also to ensure the quality of food served to students is of acceptable standard. All vending stalls to be provided with basic infrastructure. Food court yard to be well sheltered to avoid food being contaminated by air pollution, dust and pests. DUT management, together with the Department of Health, should organise nutrition awareness programmes to enlighten students about the dangers of unhealthy eating habits. / M

Compliance level of street food vendors regarding food hygiene and safety in Thulamela Local Municipality

Mukwevho, Michael Nngodiseni 18 May 2018 (has links)
MPH / Department of Public Health / Introduction: Street food vending is a source of income for billions of people around the world. In most developing countries, including South Africa street food is popular. However, most street food has been linked to outbreaks of foodborne illness. The assessment was based on the general hygiene requirement stipulated in R962 of November 2012 framed under Foodstuff cosmetics and Disinfectant Act of 1972 Purpose: The purpose of this study was to assess compliance of street food vendors with food and safety regulations in Thulamela Municipality. Method: The study used a quantitative, cross- sectional survey, descriptive design. A convenience sampling was used to sample 155 street food vendors. Data was collected using two instruments; namely, a self-administered questionnaire and an observation checklist. The data was analyzed using the Statistical Package for Social Science (SPSS) version 23.Validity and Reliability will be ensured and measures to ensure ethical considerations were adhered to. Results: A total of 155 street food vendors participated in the study. Most of the street food vendors were in the age group 25- 30 years. There were more females than males. Furthermore, the majority of street food vendors had experience of 5-10 years. The majority (n=61; 39.4%) of street food vendors were operating in Thohoyandou, while some (n=25.8%)operated in Sibasa and forty others (25.8%) operated in Shayandima. Forty-five (29%) of them were illiterate, fifty (32, 3%) did primary education, thirty two (20.6%) had secondary education, four (2.6%) had a matric certification and twenty- four (15.5%) had vocational training. More than half of the In regard to knowledge items on preventing foodborne vendors (n=100; 64.5%) did not attend food hygiene training while (n=55; 35.5%) did. Lastly about a third most (n=48; 31%) of the street food vendors were selling their food in the transport terminals. The survey results indicate that street food vendors exhibited high levels of knowledge regarding items pertaining to hand hygiene. Therefore street food vendors were highly knowledgeable with regard to how much time should be spent when washing hands with soap, the correct way of stopping bleeding while at work, important measures to keep germs away from the food, hand washing and methods of drying hands. However, the street food vendors displayed poor knowledge with regard to reasons why they should dry their hands. Regarding knowledge items on preventing foodborne illnesses, the street food vendors were knowledgeable about the symptoms that make a street food vendors stay away from the workplace, that the best way to destroy any harmful germs is to cook food to the right temperature, that a combination of washing hands, using gloves and keeping food at the right temperature are ways of preventing food borne illnesses. However, street food vendors displayed some knowledge gaps with regard to the correct detergents for washing vessels and why food handlers require some knowledge on food hygiene. A total of 155 vending stalls were observed. The results from the checklist indicated that three quarters (n=116; 75%) of the stalls were protected from the sun, wind and dust. In addition, about (n=136; 87.7%) of the stalls did not have direct access to potable water. Furthermore, about (115; 74.2 %) did not have adequate hand washing facilities and 141(91%) did not have waste disposal facilities. Animals, flies and insects were indeed evident around the stalls in 124(80%) of the 155 stalls. In addition the majority of street food handlers (136; 87.7%) did not wash their hands before preparing food. Regarding hand washing after using toilet, all of the vendors said that they washed their hands each time after visiting the toilet. This was not confirmed as the researcher did not follow the vendors into the toilets. More than three quarters (120; 77%) of the food handlers operated in clean clothes. However, only 39(25%) used an apron when handling food, while 124(80%) did not use gloves to handle food and only 24(15%) used disposable gloves. Although the street food vendors complied with wearing clean clothes, they did not consistently wear aprons and they also used bare hands to touch food. Conclusion: Although the street food vendors were knowledgeable about food hygiene and safety practices, the majority displayed poor hygienic practice and prepared food on unhygienic sites. / NRF

Avaliação da qualidade higiênico-sanitária e nutritiva de bentôs comercializados no bairro da Liberdade, São Paulo / Evaluation of the hygienic-sanitary and nutritional quality of benthos marketed in Liberdade, São Paulo

Agnes Hanashiro 14 March 2002 (has links)
A questão da segurança alimentar vem ganhando atenção global face as milhões de vítimas de doenças transmitidas pelos alimentos. Mudanças demográficas, econômicas e sociais têm provocado transformações nas sociedades que resultam em maiores riscos à saúde pública. A difusão do comércio de alimento de rua, principalmente nos grandes centros urbanos, pode ser considerada um forte reflexo dessas mudanças. Os bentôs constituem um lanche ou refeição pronta para consumo, considerado o primeiro alimento de rua no Japão, há mais de um século. Em vista das características de comercialização e dos alimentos envolvidos questionou-se a qualidade microbiológica e nutritiva de bentôs comercializados no bairro oriental em São Paulo. Foram analisadas 60 amostras coletadas durante a primavera e o verão e classificadas segundo seu risco epidemiológico. A composição variou de preparações à base de pescado cru às refeições completas. Fez-se a determinação de macronutrientes e a pesquisa de microrganismos indicadores, Escherichia coli, Staphylococcus aureus, Bacillus cereus e Salmonella spp. O valor nutritivo oscilou bastante, sendo a proporção média em relação ao valor energético total igual a 16% de proteína, 19% de lipídeos e 65% de carboidratos. O valor energético das porções variou de 136 a 885Cal. 65% das amostras foram observadas em condições higiênicas insatisfatórias. Dentre as bactérias patogênicas, B. cereus apresentou o maior risco percentual, sendo que 40% das amostras estavam fora dos padrões considerados seguros. Não houve diferença estatística na contagem microbiana em relação à época de coleta ou ao tipo de amostra. A constatação de que 73,3% das amostras encontravam-se impróprias para consumo pode se agravar, em vista das características intrínsecas e de conservação observadas. O consumo de bentôs representa um perigo potencial à saúde, sendo necessários maiores investimentos em educação em saúde a todos os envolvidos na cadeia alimentar, incluindo os consumidores, como uma forma efetiva de inibir os riscos à saúde pública. / Food safety has become one of the biggest concerns to public health authorities, in view of the millions of victims of foodborne diseases world spread. Face to the social and economical changes in the societies, the public health risks are arising. As a reflex, the popularity of street food commerce exposes the consumers\' health to other threats. Bento is an ancient Japanese tradition of bringing ready-to-eat meals wherever you are, which surpassed the modem way of life and is still a convenience way to have a fast meal. But face to the trading features and composition its quality is doubtful. Therefore, the aim of this study was to evaluate the nutritional and microbiological qualities of bentos sold at the oriental district, in São Paulo. Sixty samples were purchased during spring and summer seasons from 17 points of sale and they were classified according to their epidemiological risk. The macronutrients were determined and the sanitary conditions were evaluated through the research of coliform organisms, Escherichia coli, Staphylococcus aureus, Bacillus cereus and Salmonella spp. The samples composition ranged from raw fish to :full course meals. The nutritive value presented a large variation and the average proportions of macronutrients in relation to the total energy value was 16% of protein, 19% of lipids and 65% of carbohydrates. The portion energy value ranged from 136 to 885Cal. B. cereus posed the greatest percentage risk of contamination, among the pathogens. The hygienic conditions of the bentos were critical in 65% of the samples. No statistical difference was observed in the microbiological counts related to the sample collection season or its sort. In general, 73.3% of the samples were unsuitable for consumption and considering the time-temperature abuse such proportion can reach higher degrees. The consumption of bentos poses a potential health hazard, showing to be necessary greater investments in health education for every sector of the food chain, including the consumers, as an effective way of inhibiting the risks to public health.

Black Food Trucks Matter: A Qualitative Study Examining The (Mis)Representation, Underestimation, and Contribution of Black Entrepreneurs In The Food Truck Industry

Ariel D Smith (14223191) 11 August 2023 (has links)
<p>Food trucks have become increasingly popular over the last decade following the Great Recession of 2008. Scholars have begun to study the food truck phenomenon, its future projected trajectory, and even positioning it within social justice discourse along cultural lines; however, scholarship has yet to address the participation of Black entrepreneurs in the food truck industry.</p> <p><br></p> <p>The objective of this dissertation is to expand the perception of Black food entrepreneurs within the food truck industry by interrogating how Black food truck owners are misrepresented, under analyzed, and underestimated. Using a series of interdisciplinary qualitative methods including introspective analysis, thematic coding analysis, and case studies, I approach this objective by addressing three questions. First, I analyze movies and television to understand where Black-owned food trucks are represented in popular culture and how they are depicted. In doing so, we come to understand that Black business representation, specifically Black food truck representation consistently falls victim to negative stereotypes. These stereotypes can influence the extent to which Black food truck owners are taken seriously and seen as legitimate business leaders in their community. Second, I interview 16 Black food truck entrepreneurs to understand why the mobile food industry appealed to them and how it has become a platform for them to explore other opportunities. Finally, I review eight cities that have launched Black food truck festivals and parks within the last 6 years to gain an understanding of the collective power wielded by Black food truck owners and its impact Black communities. Moreover, this dissertation challenges the myth that collectivism does not exist among Black entrepreneurs and the Black community broadly.</p>
