Abstract

Background: The street foods provide a source of affordable nutrients to the majority of people, especially in developing countries including Ethiopia. But, since street foods are prepared and sold under unhygienic conditions, they are prone to be contaminated. So, vender’s practices towards food safety under this environment should be strictly studied. Thus, the aim of this study was to determine the level of safety practice and determinant factors of street food vendors.

Methods: A cross sectional study was conducted among 422 street food vendors to assess food safety practices and associated factors in City Administrations of West Gojjam Zone from February to March 2021. Epicollect5 software was used for data collection through smart phones. The data was bringing to MS-Excel and then to SPSS version 23 for analysis. Bivariable and Multivariable logistic regression analysis was done to identify associated factors and to control the effect of confounding variables, respectively. Significance of association was identified by p-value of < 0.05 and its strength was described using odds ratio and 95% CI.

Results: Of 422 street food vendors, 418 (99%) responded to the questions. From 418 street food vendors, 418 (100%), 232 (55.51%), 271 (64.83%), 418 (100%) and 361 (86.36%) were females, aged 20-24 years, single, orthodox, and income of 1500-5000 ETB, respectively. About 215 (51.40%) street food vendors had good food safety practice. Primary educational status (AOR=0.57, 95% CI=0.35-0.99), cannot read and write (AOR=0.17, 95% CI=0.08-0.37), monthly income 5001-8500 ETB (AOR=2.57, 95% CI=1.06-6.22), inspection (AOR=3.64, 95% CI=2.05-6.46), training (AOR=3.73, 95% CI=1.94-7.16), vending experience 4-6 years (AOR=1.89, 95% CI=1.14-3.13), vending experience 7-9 years (AOR=3.67, 95% CI=1.21-11.11) and poor knowledge of food safety (AOR=0.48, 95% CI=0.30-0.78) were factors showed statistical significance.

Conclusion: In this study, half of the study subjects were found in practicing a beter way to keep food safety and healthy. Regular training and improving knowledge level, support in improving economic status and inspection are important activities to be held to improve food safety practices of street food vendors.

Introduction

Street vended foods are defined as Ready-To-Eat (RTE) foods and beverages that are sometimes prepared by vendors in the streets and other public places, and mostly sold to consumers for immediate or later consumption without any further preparation or processing [1-3]. Street-vended foods include foods as diverse as meat, fish, fruits, vegetables, grains and cereals based ready to eat foods, frozen produce and beverages [2]. However, Street foods, as those are generally prepared and sold under unhygienic conditions, with limited access to safe water, sanitary services, or garbage disposal facilities they are exposed to food poisoning, food borne diseases and food safety problems [2,4]. Most of the foods provided by street vendors are not protected against insects, dust etc., which may harbor foodborne pathogens [5]. The rising concern about food-borne illness has questioned the knowledge of the street food vendors to constitute safety practices for food handling [6]. Food safety problems are particularly becoming an increasingly serious threat to public health in developing countries [7]. Food Borne Diseases (FBD) are an important cause of morbidity and mortality worldwide. The burden arising from unsafe food handling and chemical and parasitic contaminants in the food [8]. World Health Organization, Foodborne Disease Burden Epidemiology Reference Group (FERG) estimated that 31 Food Borne Diseases (FBDs) resulted in over 600 million illnesses and 420,000 deaths worldwide in 2010 [9]. Studies from different parts of the world approved that street vended foods have remarkable contribution to the increased burden of foodborne diseases. Bacteriological assessments done on street vended food in the globe indicates about 80 - 93% were contaminated with pathogenic bacteria [10,11]. In Ethiopia, as in other developing countries, it is difficult to evaluate the burden of food borne pathogens because of the limited scope of studies and lack of coordinated epidemiological surveillance systems. Under-reporting of cases and the presence of other diseases considered to be of high priority may have overshadowed the problem of foodborne pathogens [12-14]. Unsafe food-production processes and food safety practices aggravate the burden of food borne diseases. To the best of our awareness, food handlers’ safety practices have a great role in the production of healthy food for consumers; so as to minimize the level of contamination and the burden of food borne diseases. In urban areas like City Administrations in West Gojjam Zone, dining outside home in street vendors observed as a common practice among numerous consumers due to increased urbanization, increased number of labor workers and seeking of low cost foods for low income groups. Therefore, the finding of this study is important for respective health offices to know the gap of Street Food Vendor’s on Food Safety practices so as to formulate intervention mechanisms. This research can add new knowledge in the area about the practice of street vendors. The finding also important for health department to plan successful monitoring and evaluation systems of health offices on methods formulated to improving food safety among street food vendors. For researchers, it serves as source of information concerning vendor’s status of practice and factors associated to conduct other researches in the area for the future.

Methods and Materials

Study design and settings

A cross-sectional study was conducted to assess food safety practice and associated factors among street food vendors in City Administrations in west Gojjam zone. The study was conduct from February to March, 2021. The study was conducted in City Administrations in West Gojjam Zone, Amhara Regional State. West Gojjam Zone has 6 city administrations namely Adet, Merawi, Durbete, Bure, Finoteselam and Dembecha city administrations. They all are found about in northwest of Addis Ababa with different distance and to west and South directions from Bahir Dar. The total population in six City Administrations is 164 292, of which about 81 137 are males while 83 155 are females. The out dining establishments observed in West Gojjam are hotels, restaurants, and street/small scale/ food venders. From those establishments, maximum numbers of customers flow to small scale/street/ food vendors due to their fair costly and easily accessibility of those establishments around working areas. The total numbers of licensed street food vendors in those Cities are 1096/Sources: respective City Administrations Trade and Market development office. Due to dramatic increment of unemployment and expansion of urbanization, both the number of street food vendors and the customers for street foods become increased. Shero, Firfir, Pasta, Mekoreni, Tomato, Egg, Ambasha, Vegetables etc… are the common street food types provided by vendors in the study area.

Source and study population

Street food vendors found in City Administrations of West Gojjam Zone are the source population. Street food vendors found in six Cities, which are on work during the data collection time, are the study population.

Inclusion and exclusion criteria

Street food vendors in Dembecha, Finote selam, Bure, Durbete, Merawi and Adet City Administrations were included in the study. Street food vendors who are licensed but not functional due to different reasons during data collection have been excluded from the study.

Sample size determination and sampling procedures

The sample size was determined by using proportion of practice via using single population proportion formula(n= (za/2)2 *p(1-p)/ d2) with the assumptions of 95% CI, 5% marginal error, 53% of the study units have good practice of food safety and 10% non-response rate. Based on this 383 subjects and when add 10 % none response rate the sample units become 422. But since the target population is below 10000, the sample size was adjusted by correction formula N*n/N+n. Then total street food vendors in the study area are 1096, so adjusted sample size was 305. However, in order to increase accuracy and precision, the first sample size as it is (422) was used. List of street food vendors in all six Cities were taken from Trade and Market Development office, Registration and Licensing unit. Then all street food vendors from six/6/ Cities were merged and numbered together. The study subjects then selected by using simple random sampling technique/online random number generator calculator/.

Data collection tools and techniques

Data was collected through a face-to-face interview using structured questionnaires and observational checklists. The questionnaire and checklist designing processes was guided by relevant information from previous literatures and the guidelines provided by WHO regarding street food vending safety practices. The questionnaire and checklist was prepared in English first and then translated into the local language (Amharic) to have a clear and common understanding of all respondents who have been participated in this study. The data collectors and supervisors were degree holder officers/Environmental Health/Sanitary Officers/ in the Health Sector of those City Administrations. Smart mobile was used as a tool for data collection through Epicollect5 Software. The project template was created on Epicollect5 software by the investigator carefully with all required indicators. The purpose and objectives of the study have been clearly explained to each study participants before beginning of data collection.

Study variables

Dependent/outcome variable: Food safety Practice of street food vendors (Good or Poor) Independent variables/study variables Socio demographic variables: Age, Sex, Marital status, Educational status, Religion, Family size and Income level.

Food safety knowledge of street food vendors;

Access to information and regulation variable: Training, Inspection by supervisors, Vending experience, Feedback from customer and Health certificate.

Conditions of vending environment: Availability of Water, Type of water source, Availability of Waste disposal system (Liquid waste disposal system and Municipal solid waste collection) and Availability of latrine.

Operational definitions

Food safety knowledge: The knowledge on food safety was measured by providing 14 questions for the participants. The answers were registered as one for correct responses and zero for incorrect responses. The scores then changed to percent. Vendors who can give true answer for at least 8 or above questions (>50%) have been classified as having good knowledge whereas vendors who can answer 7 or below questions correctly (<50%) was considered as having poor knowledge.

Food safety practice: The food safety practice was assessed by providing 22 questions for participants. Participants practicing correctly were score 1 while those practicing incorrectly were score 0. The result from 22 questions was again changed to 100 (percent). Vendors who are practicing 12 or more correctly (> 50%) have been considered as having good practice while those vendors who are practicing 11 or bellow (<50%) was considered as having poor practice.

Availability of water: Based on WHO guideline for street food vendors, to say there is access for water, the production and sales unit should have their own supplies of potable water whether it is from a central system or an individual source, such as a hand pump [2].

Availability of waste disposal systems:

Liquid waste disposal: Based on WHO standard for street food vendors, to the liquid waste is disposed in appropriate way; it should be emptied into the nearest sewer or drain. Some form of a trap should be used to ensure that only liquid waste is discharged into the sewer or the drain [2].

Solid waste disposal: Based on the standard provided by WHO, solid waste generated from street food production should be kept in covered containers on site to be removed at least once daily by the public garbage collection system provided by the municipalities [2].

Availability of latrine: In small food establishments, the minimum requirement is one toilet for every 30 women and every 60 men employee and customers.

Data quality assurance

Quality of data was assured by designing the template intensively and pre-testing of the questionnaires/template in 5% of participants on street food vendors selected from Jiga town and completeness of the template was assessed before the actual data collection. The data collectors and supervisors were first take training about data collection to have common understanding and let them to practice on Epicollect5 Software until become perfect to collect the required data by already prepared template. At every moment the collected data was uploaded and the supervisors were checking each sample immediately after collection for its completeness. If anything found that to be corrected, then the supervisors were informing the data collector immediately before the completion of data collection.

Data management and analysis

The data collected through Epicollect5 were exported directly to MS-Excel and then exported to SPSS version 23 for analysis. To describe the study subjects, descriptive statistics, including frequencies, mean, standard deviation, and percentage have been used. Bivariable logistic regression analysis was done to identify factors associated with knowledge and practice of food safety and hygiene. Multivariable logistic regression analysis was used to control the effect of confounding variables. Variables with p-value < 0.05 have considered as statistically significant. The association and its strength also noticed by using odds ratios with 95% confidence interval/CI/. Variables with significant association were identified by the basis of, CI and p-value. Data presentation of the results after analysis has done by using graphs, tables, and narration.

Ethical considerations

Ethical clearance was obtained from Bahir Dar University College of Medicine and Health Sciences Institutional Review Board (IRB). Written permission was also taken from Health and Trade Department in west Gojjam zone, and then oral permission from each City Administration health and trade sector leaders was obtained to get important information and to collect the data. Informed consent was again obtained from each study participant after explaining the objective of the study. All the information about the study participants have been kept in a file without name but a code for each and not be given to anyone except the principal investigator. Participation was voluntary based.
