Abstract
Background Food-borne infections continue to be a major public health problem at the international level. The issue becomes more serious in developing countries like Ethiopia. Objective This study aimed to examine the prevalence of Salmonella and Shigella species and intestinal parasites, as well as antimicrobial resistance patterns and associated factors among food handlers at the University of Gondar cafeteria in northwest Ethiopia. Methods An institutional-based cross-sectional study was conducted from February to June 2021 in the University of Gondar cafeterias. Data related to the socio-demographic characteristics and hygienic practices of study participants were collected using structured questionnaires. A total of 290 stool samples were collected from food handlers. Culture and conventional biochemical tests were used to isolate the Salmonella and the Shigella species. Wet mount, Formol-ether concentration, and Kato Katz techniques were applied to identify intestinal parasites. Additionally, drug susceptibility tests were performed using the disk diffusion method. Statistical analysis was done using SPSS version 26. Results Of 290 food handlers' stool samples analyzed, Twenty-seven 27 (9.3%) were positive for both Salmonella and Shigella species. The prevalence of Salmonella and Shigella species was 16 (5.5%) and 11 (3.8%), respectively. Most of the isolated pathogens were resistant to tetracycline 19 (70.4%), and trimethoprim/sulphamethoxazole 19 (70.4%). The overall rate of multi-drug resistant Shigella and Salmonella isolate was 59.3%. Besides, Fifty-seven 57 (19.7%) of the participants were positive for one or more intestinal parasites. The most prevalent intestinal Parasitosis was E. histolytica/dispar 22 (7.6%), followed by G. lamblia 13 (4.5%), and Ascaris lumbricoides 11 (3.8) not washing hands after using the toilet (AOR: 4.42, 95% CI: 1.57, 10.56), and consuming unpasteurized milk (AOR: 3.14, 95% CI: 1.65, 3.96), were factors significantly associated with the prevalence of Salmonella, and Shigella infection. Similarly, not washing hands after using the toilet (AOR: 2.19, 95% CI: 1.0, 1.4), and consuming unpasteurized milk (AOR: 10.4, 95% CI: 3.8, 28.8), were factors significantly associated with the prevalence of intestinal parasites infection. Conclusion The prevalence of intestinal parasites, Salmonella, and Shigella species was high. Therefore, it is imperative to implement a public health policy that includes ongoing microbiological surveillance.

Ango TS, Gelaw NB, Zegene GM, Teshome T, Getahun T. Prevalence and antimicrobial susceptibility profile of bacteria isolated from the hands of housemaids in Jimma City, Ethiopia. Front Public Health 2024; 11:1301685. [PMID: 38348381 PMCID: PMC10859430 DOI: 10.3389/fpubh.2023.1301685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 12/27/2023] [Indexed: 02/15/2024] Open
Abstract
Introduction Bacterial pathogens continue to be a major cause of foodborne gastroenteritis in humans and remain a public health problem. Housemaids operating inside a kitchen could be the source of infection and may transmit disease-inflicting pathogens through contaminated hands. Objective This study aimed to assess the prevalence and antimicrobial susceptibility profile of bacteria isolated from the hands of housemaids in Jimma City, Ethiopia. Methods A laboratory-based cross-sectional study was employed among 234 housemaids. Hand swab samples from the dominant hand of the study participants were collected under sterile conditions following standard operating procedures. Then, in the laboratory, the swabs were inoculated aseptically using streak-plating methods on the growth media, such as mannitol salt agar [Staphylococcus aureus and coagulase-negative staphylococci], MacConkey agar [Klebsiella species and Proteus species], salmonella-shigella agar [Salmonella species and Shigella species], and eosin methylene blue agar [Escherichia coli (E. coli)]. In addition, a set of biochemical tests was applied to examine bacterial species. Data were double-entered into EpiData version 3.1 and then exported to the Statistical Package for Social Science (SPSS) version 26 for further analysis. Descriptive analyses were summarized using frequency and percentage. Results The proportion of housemaids' hands containing one or more positive bacterial isolates was 72% (95% CI: 66.2, 77.8). The dominant bacterial isolates were Staphylococcus aureus (31.6%), Escherichia coli (21.3%), Salmonella species (1.3%), Shigella species (6.7%), Klebsiella species (23.1%) and Proteus species (14.7%). Fingernail status (AOR =15.31, 95% CI: 10.372, 22.595) and the removal of a watch, ring, and bracelet during hand washing (AOR = 20.844, 95% CI: 2.190, 9.842) were significantly associated with the prevalence of bacterial isolation. Most Staphylococcus aureus isolates were susceptible to chloramphenicol (98.6%). Escherichia coli isolates were susceptible to tetracycline (75%), ceftriaxone (79.2%), chloramphenicol (87.5%), and ceftazidime (77.1%). Eighty percent of isolated Shigella species were susceptible to chloramphenicol and gentamicin respectively. In addition, Klebsiella and Proteus species exhibited high susceptibility to chloramphenicol. However, their isolates showed resistance against a number of the tested antimicrobials. Staphylococcus aureus isolates (28.2%) were resistance to tetracycline. Moreover, One-quarter of Escherichia coli isolates were resistance to tetracycline, ceftriaxone, chloramphenicol, and ceftazidime. Whereas 46.7% and 48.5% of isolated Shigella species and Proteus species were resistance to tetracycline and ceftriaxone. Conclusion The hands of housemaids are important potential sources of pathogenic bacteria that would result in the potential risk of foodborne diseases. Most bacteria isolates were resistant to tetracycline, ceftriaxone, and ceftazidime. Therefore, practicing good hand hygiene helps to prevent and control the spread of antimicrobial-resistant microbes.

Abstract
Background Foodborne illnesses are the main cause of morbidity and mortality in the twenty-first century, and food handlers are the main source of these illnesses. Objective The study aimed to assess the prevalence of intestinal parasites, enteric bacteria, antimicrobial susceptibility patterns, and associated factors among food handlers working in a food and drinking establishment in Yabelo town, Borena zone, Southern Ethiopia, in 2022. Methods A facility-based cross-sectional study design was employed to assess the food handler's state of health. Data were gathered using semistructured questionnaires and observational checklists, and 396 regular stool samples were collected. Samples were examined with microscopy and bacteriological culture to isolate enteric bacteria. Statistical Package for the Social Sciences, version 26 The factors that had a P-value of <.05 were considered statistically significant. Result Of the 396 stool samples collected, 164 (41.4%) were tested positive for intestinal parasites, while 40 (10.1%) were positive for enteric bacteria (Salmonella and Shigella). Among intestinal parasites, the most predominant parasite was Ascaris lumbricoides 48 (12.1%). All isolates of Salmonella and Shigella showed resistance to ampicillin. In multivariable analysis, not trimming fingernails regularly (AOR = 2.02, 95% CI 1.97-5.37), not washing hands with soap after the toilet (AOR = 3.02, 95% CI 2.37-5.62), and eating raw food (AOR = 2.1, 95% CI 1.79-6.51) have a significant association with the prevalence of bacteria and parasites. Conclusion The majority of food handlers had poor hygiene practices, and the prevalence of parasites and bacteria was high in the study setting. Educational status, eating raw vegetables or fruit, hand washing after the toilet, and fingernail trimming have associations with the health status of food handlers.

Abstract
Objective Hand hygiene is a milestone, cost-effective, and convenient strategy to prevent the transfer of pathogenic micro-organisms. However, housemaids operating inside a kitchen can be the source of infection. In addition, hand hygiene among housemaids working in dwellings was underexplored. This study aimed to assess the hand hygiene status and associated factors among housemaids working in communal living residences in Jimma City, Southwest Ethiopia. Methods A total of 230 housemaids were included in this cross-sectional study. Total samples were proportionally allocated for each residence and a simple random sampling technique was applied to select the study participants. Hand hygiene status and relevant characteristics were collected through face-to-face interviews and observations. Hand swab samples were collected and tested for bacterial contaminants. Then, it was inoculated aseptically using streak-plating methods on mannitol salt agar (MSA), MacConkey agar (MCA), salmonella-shigella agar (SSA), and eosin methylene blue (EMB) agar and then incubated at 37 °C for 24 h. Data was edited, cleaned, and double-entered into Epidata version 3.1 and then exported to the statistical package for social science statistics version 26 for further analysis. Binary logistic regression was used to identify associated factors. Statistically significant was declared at P value < 0.05. Results Two hundred twenty-five housemaids were interviewed with a response rate of 97.8 %. The results showed that the proportion of good hand hygiene status among the housemaids was only 28.0 %. Although the majority of participants reported washing their hands frequently, the prevalence of bacterial contaminants on their hands was high at 72 %. The study identified several factors associated with hand hygiene status, including the occupational status of heads of households (AOR = 0.030, 95 % CI: 0.003, 0.348; P = 0.0050), the effectiveness of the heads of household (AOR = 13.955, 95 % CI: 1.442, 13.500; P = 0.0230), and the removal of accessories during handwashing (AOR = 20.844, 95 % CI: 2.190, 9.842; P = 0.0080). Conclusion Overall, the hand hygiene status of housemaids was found to be poor and influenced by demographics and other relevant characteristics. The study emphasizes the need for a multimodal strategy involving household heads, local and national authorities, and other stakeholders to raise awareness and advocate for hand hygiene to prevent communicable diseases in the wider community, particularly in the study area.

Abstract
Background In Ethiopia, salmonellosis is one of the most common zoonotic and foodborne illnesses. Ethiopia continues to be at risk for its fast-expanding medication resistance. For the development of preventative and control methods, summarized knowledge regarding salmonellosis is necessary. Determining a thorough evaluation of the prevalence, serotypes, and antibiotic resistance of Salmonella in humans and animals from January 1, 2010, to December 30, 2022, in Ethiopia was our goal. Methods To find Salmonella related articles that published in English, we used the Google Scholar and PubMed search engines. Three researchers conducted the eligible studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, making sure to include the necessary keywords. If studies were duplicates, incomplete publications, or reported without an antimicrobial test were excluded. Excel 2013 was used to calculate frequencies and tabulate data. Results There were a total of 43 investigations from food handlers, diarrhoeic patients, and animals. The prevalence rates ranged from 1% to 10% and 1% to 13% among food handlers and diarrhoea patients, respectively. The highest prevalence was among pigs (41.6%). S. Anatum in animals and S. Typhimurium in people were the predominant serotypes. Amoxicillin and ampicillin were claimed to be 100% resistant in human studies. The highest recorded resistances for ceftriaxone and ciprofloxacin were 16.7% and 100%, respectively. Animal studies revealed that Salmonella resistances to ampicillin, streptomycin and tetracycline were 100%, 90%, 86.4%, respectively. S. Kentucky showed complete resistance to tetracycline, ampicillin, gentamicin, ciprofloxacin, and streptomycin. Conclusion The prevalence of Salmonella among asymptomatic food handlers, diarrheal patients and animals were high in Ethiopia. S. Typhimurium that have the zoonotic importance was presented predominantly in human study. High levels of resistances were showed to tetracycline, ampicillin and streptomycin in animal studies. Salmonellosis prevention and control techniques should be strengthened.

Abstract
Background Shigellosis is the most common cause of epidemic dysentery found worldwide, particularly in developing countries, where it causes infant diarrhea and mortality. The prevalence of Shigella species resistant to commonly used antimicrobial drugs has steadily increased. The purpose of this review is to describe the prevalence and antimicrobial resistance (AMR) characteristics of Shigella species in East Africa between 2015 and 2022. Methods Studies were identified using a computerized search of Medline/PubMed, Google Scholar, and Web of Science databases, with a detailed search strategy and cross-checking of reference lists for studies published between 2015 and 2022. Articles presenting data on prevalence and AMR, accessibility of the full-length article, and publication dates between 2015 and 2022 were the eligibility criteria for inclusion in the review. Original research reports written in English were considered. The heterogeneities of the studies were examined, and a meta-analysis was performed to estimate the pooled prevalence and AMR using a random effects model. Results The pooled prevalence of Shigella species in East Africa was 6.2% (95% CI -0.20-12.60), according to an analysis of 22 studies. Shigella species prevalence was 4.0% in Ethiopia, 14.6% in Kenya, 0.7% in Sudan, 5.2% in South Sudan, and 20.6% in Somalia. The association of Shigella infection significantly varied among the countries (p = 0.01). Among the antibiotics tested, most Shigella isolates were susceptible to ciprofloxacin, norfloxacin, nalidixic acid, and ceftriaxone. Despite the fact that the reports varied in study sites and time, Shigella species were resistant to tetracycline, ampicillin, amoxicillin, chloramphenicol, and co-trimoxazole. Conclusion The pooled estimate indicates high burden of Shigella infection in East Africa, as well as a high proportion of drug resistance pattern to tetracycline, ampicillin, chloramphenicol, and amoxicillin. Therefore, initiating and scale-up of performing drug susceptibility test for each shigellosis case need to be considered and strengthened.

Abstract
Background Shigella and parasitic infections are common public health problems throughout the world. Shigellosis is an acute gastroenteritis infection and one of Ethiopia's most common causes of morbidity and mortality, especially in children under five. High resistance rates to commonly used antibiotic agents have been documented in different locations in Ethiopia. Objective This study aimed to characterize the antimicrobial features of the Shigella species isolated from children under five years of age with acute diarrhea in Addis Ababa, Ethiopia. Methods Using a cross-sectional study, freshly passed fecal specimens were collected for intestinal parasite and bacterial isolation. Fecal samples for bacterial identification were placed immediately in Cary-Blair media and transported to the Ethiopian Public Health Institution (EPHI) laboratory. Antimicrobial susceptibility testing (AMST) was conducted using the disk diffusion method. Data were described using descriptive statistical tools. The association of independent and dependent variables was evaluated with logistic regression. A P value ≤0.05 was considered statistically significant. Results The prevalence of intestinal parasites was 8.2% with seven different species. Among the 534 stool-cultured specimens, 47 (8.8%) were positive for Shigella species. Antimicrobial susceptibility testing (AMST) showed that 100%, 93.6%, 80.9%, 72.3%, and 57.5% were susceptible to norfloxacin, nalidixic acid, ciprofloxacin, gentamicin, and cefoxitin, respectively. However, 100% of the isolates were resistant to amoxicillin and erythromycin. More than 50% of the isolates were resistant to three and above antibiotics, while none of them were susceptible to all the antibiotics tested. All risk factors assessed did not show a statistically significant association with Shigella infection. Conclusion The high levels of antibiotic resistance observed among the commonly prescribed antibiotics are alarming. The emerging resistance to ciprofloxacin and nalidixic acid signals a severe public health threat in the management of shigellosis. Raising awareness about resistance and educating health professionals, policymakers, and the public can help improve the quality of patient care and rational antibiotic use.

Abstract
BackgroundFoodborne disease (FBD) affects millions of people each year, posing a health burden similar to malaria, tuberculosis or HIV. A recent World Bank study estimated the productivity losses alone attributed to unsafe food within Africa at $20 billion in 2016, and the cost of treating these illnesses at an additional $3.5 billion. Ethiopia faces multiple food safety challenges due to lack of infrastructure and basic pre-requisites for food safety such as clean water and environment, washing facilities, compounded by limited implementation of food safety regulations, and a lack of incentives for producers to improve food safety. A consolidation of our understanding and evidence of the source, nature and scale of FBD in Ethiopia is needed to inform policy and future research. We performed a Systematic Literature Review (SLR) of publications on FBD occurrence in Ethiopia including hazard presence and impact.MethodThe SLR followed Cochrane and PRISMA guidelines. We searched PubMed and CAB-Direct for relevant publications between 1990 and 2019 (inclusive). Observational studies and reviews were included. Two reviewers screened titles and abstracts, and retained publications were reviewed in full for quality and data extraction.ResultIn total 128 articles met the inclusion criteria. Most articles focused on the identification of biological hazards in food. High levels of microbial contamination in different food value chains were often found in the small, ad hoc, observational studies that dominated the literature. Raw milk (22/128, 17.0%) and raw beef (21/128, 16.4%) were the most studied food products. Foodborne (FB) parasites were often found at higher rates in food than bacterial and viral pathogens, possibly due to differences in ease of identification. High levels of bacterial contamination on the hands of food handlers were widely reported. There were no reports on the incidence of human FBDs or resulting health and economic impacts.ConclusionOur findings reflect existing concerns around food safety in Ethiopia. A lack of substantial, coordinated studies with robust methodologies means fundamental gaps remain in our knowledge of FBD in Ethiopia, particularly regarding FBD burden and impact. Greater investment in food safety is needed, with enhanced and coordinated research and interventions.

Abstract
Background Under five children are at risk of diarrhea-associated morbidity and mortality. Salmonella and Shigella are major causes of diarrhea in under-five children, especially in developing countries. This study aimed to assess the prevalence, antimicrobial resistance pattern, and associated factors of Salmonella and Shigella among under-five diarrheic children in Debre Markos town public health facilities. Methods A cross-sectional study was conducted at public health facilities in Debre Markos town using a consecutive convenient sampling technique. Data on socio-demographic and associated factors were collected using a structured questionnaire. Salmonella serovars and Shigella species were identified using MacConkey, Xylose Lysine Deoxycholate, Salmonella Shigella agar, and biochemical tests. The antimicrobial resistance pattern was determined by using the modified Kirby-Bauer disk diffusion technique. Results The overall prevalence of Salmonella and Shigella was 11.7% (26/222; 95% CI = 7.2-17.5%). Isolated Salmonella serovars showed a higher rate of resistance (85.7%, 6/7) for both Ampicillin and Amoxicillin/Clavulanic acid while Shigella isolates showed a higher resistance rate to Amoxicillin/Clavulanic acid (78.9%, 15/19) and Ampicillin (73.7%, 14/19). The overall multidrug resistance (MDR) rate of Salmonella and Shigella isolates was 88.5% (23/26). Parent/guardian educational status ≤ elementary school (AOR = 3.783; 95% CI = 1.28-11.19; P = 0.016), presence of two or more under-five children in the family (AOR = 8.999; 95% CI = 2.93-27.69; P < 0.001), unimproved source of drinking water (AOR = 5.010; 95% CI = 1.56-16.10; P = 0.007), the habit of storing cooked foods for later use (AOR = 3.199; 95% CI = 1.07-9.54; P = 0.037), attendance of the child at social gatherings (AOR = 5.387; 95% CI = 1.78-16.35; P = 0.003), and infrequent child fingernail trimming (every ≥ 2 weeks; AOR = 4.693; 95% CI = 1.47-14.94; P = 0.009) showed statistically significant association with the prevalence of culture-confirmed Salmonella and Shigella isolates. Conclusion The prevalence of culture-confirmed Salmonella and Shigella isolates was significantly high in the study area. Salmonella and Shigella isolates exhibited a high rate of MDR pattern. Parent/guardian education level below the elementary school, the presence of two or more under-five children in the family, using unimproved water source, a habit of storing cooked food, and infrequent fingernail trimming were independent predictors of culture-confirmed Salmonella and Shigella. Therefore, besides public health measures, regular surveillance of the prevalence and antimicrobial resistance pattern of Salmonella and Shigella should be routinely practiced in the study setting.

Carriage of Antibiotic Resistant Bacteria and Associated Factors Among Food Handlers in Tamale Metropolis, Ghana: Implications for Food Safety. Microbiol Insights 2023; 16:11786361221150695. [PMID: 36726578 PMCID: PMC9885032 DOI: 10.1177/11786361221150695] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 12/26/2022] [Indexed: 01/30/2023] Open
Abstract
Background Bacteria pathogens constitute a significant proportion of diarrhoea-causing food contaminants. Transmission of antibiotic resistant foodborne pathogens to humans is a major threat to food safety, especially in developing countries where quality hygiene and sanitation facilities are lacking. Factors related to antibiotic use, sanitation and hand hygiene have been associated with the spread of infectious diseases as well as antibiotic resistant bacteria. Proper food handling ensures that food is not contaminated with potential pathogenic bacteria. This study assessed the carriage of antibiotic resistant bacteria and associated factors. Methods A cross-sectional study was conducted among food handlers who sell ready to eat food in the Tamale metropolis of the Northern Region of Ghana. Food vending stations with huge customer base were randomly selected and the food handlers recruited using written informed consent. Structured questionnaires were used to collect participants sociodemographic details and information on sanitation, hand hygiene practice and antibiotic use. Sterile cotton swabs soaked in phosphate buffered saline was used to swab the palms of participating food handlers for bacteria isolation. All identified bacteria were tested for susceptibility to 12 antibiotics. Results In all, 406 food handlers participated in this study, the mean (SD) age was 26.5 (2.64) years. Bacteria isolated were predominantly Staphylococci 60 (14.8%) and Escherichia coli 54 (13.3%). All the isolates were resistant to at least one antibiotic tested. The isolates showed high resistance to broad-spectrum antibiotics such as ampicillin (40.0%-75.0%), tetracycline (40.0%-80.0%), amoxiclav (20.0%-80.0%) and chloramphenicol (7.7%-50.0%). Logistic regression model revealed that the carriage of antibiotic resistant bacteria by food handlers was significantly associated with age, educational level, years on the job, training in food preparation, hygiene practice, water source, type of toilet facility used and antibiotic use. Conclusion Street food handlers could be potential sources of food-borne transmission of antibiotic resistant bacteria.

Abstract
Handwashing plays a major role in preventing the spread of infection and, if poorly implemented, leads to different illnesses. However, the quality of water meant for handwashing and handwashing practice and hand hygiene conditions of food establishment customers are overlooked issues, unlike drinking water and hygienic conditions and practice of food handlers. This study aimed to assess the microbial quality of water used for handwashing and hygienic practice and the status of customers of food establishments and associated factors in Ginjo Kebele, Jimma town, Southwest, Ethiopia. A cross-sectional study design was employed in July 2022. Forty water and 40 hand swab samples were taken and analyzed for total coliform and E. coli using the spread plate method. Handwashing facility conditions and the handwashing practices of customers were assessed using a checklist and questionnaire. The data were analyzed by SPSS version 23 software. The median handwashing water total coliform count was 390.0 CFU/ml. The median hand swab samples' total coliform and E. coli load were 21.6 and 4.8 CFU/cm2, respectively after handwashing practice. There was an uphill correlation between the handwashing water and hand swab sample total coliform load (r = .34, P = .032). The mean handwashing efficacy for the removal of total coliform was 25.8%. The microbial load was varied with the type of water container used, method of taking water from the container, handwashing practice, and hand drying. The microbial quality of handwashing water and hand swab samples didn't comply with the acceptable limit. Thus, governmental bodies should work to improve the handwashing practice of communities. Food establishment owners should treat water for handwashing, clean the water containers, handle the water properly, and avail soap and poster demonstrators to the handwashing facilities. The customers should also comply with proper hand washing practices and reduce hand contamination.

Prevalence and Associated Risk Factors of Intestinal Parasites and Enteric Bacterial Infections among Selected Region Food Handlers of Ethiopia during 2014-2022: A Systematic Review and Meta-Analysis. ScientificWorldJournal 2022; 2022:7786036. [PMID: 36277127 PMCID: PMC9581692 DOI: 10.1155/2022/7786036] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 09/27/2022] [Indexed: 11/06/2022] Open
Abstract
Food-borne disease due to intestinal parasites (IPs) and enteric bacterial infections (EBIs) remain a major public health problem. Food handlers, individuals involved in preparing and serving food, working with poor personal hygiene could pose a potential threat of spreading IPs and EBIs to the public. The aim of this study was to examine the overall prevalence and risk factors of IPs and EBIs among food handlers in four selected regions of Ethiopia. Scientific articles written in English were recovered from PubMed, ScienceDirect, Web of Science, Google Scholar, Cochrane Library, and other sources from Google Engine and University Library Databases. “Prevalence,” “Intestinal Parasites,” “Enteric Bacterial Infections,” “Associated Factors,” “Food Handlers,” and “Ethiopia” were the search terms used for this study. For critical appraisal, PRISMA 2009 was applied. Stata software version 16 was used to perform the meta-analysis. Heterogeneity and publication bias were evaluated using Cochran's Q, inverse variance (I2), and funnel plot asymmetry tests. A random-effects model was used to calculate the pooled burden of IPs and EBIs and its associated factors among food handlers, along with the parallel odds ratio (OR) and 95% confidence interval (CI). For this meta-analysis, a total of 5844 food handlers were included in the 20 eligible studies. The overall pooled prevalence of IPs and EBIs among food handlers in four selected regions of Ethiopia was 29.16% (95% CI: 22.61, 35.71), with covering (25.77%) and (3.39%) by IPs and EBIs, respectively. Ascaris lumbricoides, Entamoeba histolytica/dispar, Giardia lamblia, and hookworm were the most prevalent IPs among food handlers with a pooled prevalence of 7.58%, 6.78%, 3.67%, and 2.70%, respectively. Salmonella and Shigella spp. were the most prevalent EBIs among food handlers with a pooled prevalence of 2.78% and 0.61%, respectively. A high prevalence of IPs and EBIs among food handlers was observed in Oromia (38.56%; 95% CI: 29.98, 47.14), while a low prevalence was observed in the Tigray region (19.45%; 95% CI: 6.08, 32.82). Food handlers who had not taken food hygiene training (OR: 0.68, 95% CI: −0.34, 1.69), untrimmed finger nail (OR: 2.23, 95% CI: 1.47, 2.99), lack of periodic medical checkup (OR: 1.52, 95% CI: 0.41, 2.64), lack of handwashing habits (OR: 1.97, 95% CI: 0.53, 3.41), and eating raw vegetables and meat (OR: 2.63, 95% CI: 0.92, 4.34) were factors significantly associated with the prevalence of IPs and EBIs. The prevalence of IPs and EBIs was high in the selected Ethiopian region (Amhara, Oromia, SNNPR, and Tigray) food handlers along an increasing prevalence trend from 2014 to 2022. Therefore, this study recommends the provision of proper health education and training regarding personal hygiene, hand washing, food handling, medical checks, as well as raw vegetable and meat safety.

Abstract
This study aimed to determine antimicrobial- resistance (AMR) enteric bacterial load and associated factors among Food Handlers (FHs) ofMass Catering Center (MCC), Ethiopia. From January to June 2020, a laboratory-based cross-sectional study was conducted using the standard Swab microbiological analysis method and the Kirby-Bauer disc diffusion method on 160 randomly selected FHs and food serving areas and analyzed with RStudio- 1.2.5033 for contamination, resistance level, and source determination. The contamination of AMR Escherichia coli was33.3% (95% CI, 31.5%, 36.4%), Salmonella 30% (95% CI, 29.8%, 36.0%) and Shigella 20% (95% CI, 19.2%, 26.9%) among the hand of FHs serving in MCC. The contamination was more likely associated with low work experience [AOR, 1.42 (95% CI: 1.22-1.87)], a low educational level [AOR, 1.62 (95% CI: 1.52-189)], irrational drug use characteristics [AOR, 1.75(95% CI: 1.64-2.00)], lack of sufficient food safety knowledge [AOR, 1.52 (95% CI: 1.32-1, 67)] of the FHs and the sanitary condition of the food serving area [AOR:1.98 (95% CI, 1.45, 2.53)]. The contamination of the hand of FHs serving in the MCC with AMR enteric FBB at the University cafeteria could indicate the likelihood of the occurrence of foodborne outbreaks.

Abstract
Background Food-borne infections are common public health problems worldwide. A street food handler with poor personal hygiene contributes to the transmission of intestinal parasites and enteric bacteria to the public via contaminated foods. In Ethiopia, health risks associated with street food are common. Previous studies in this area are scanty. Hence, the aim of this study was to determine the prevalence of intestinal parasites, enteric bacterial infections, and antimicrobial susceptibility among street food handlers in Jimma town. Methods A cross-sectional study was conducted from October to December 2020 among 260 street food handlers in Jimma town. A semi-structured questionnaire was used to collect data through face-to-face interviews. About 3 grams of the fecal specimen were collected from each food handler for bacterial culture and concentration techniques. The data were entered into Epi-Data 3.1 and analyzed by SPSS version 20. Associated factors were identified by using binary logistic regression analysis. A statistically significant association was determined at a p-value less than 0.05. Results The overall prevalence of intestinal parasites and enteric bacterial pathogens was 39.2% (33.3%–45.2%) and 8.85% (5.4%–12.3%), respectively. Ascaris lumbricoides (18.5%) and Salmonella (8.1%) were the most predominant parasite and enteric bacterial isolates, respectively. Not trimming fingernails (AOR = 2.884; 95% CI: 1.682–4.945) and not washing hands with soap after toilet (AOR = 3.342; 95% CI: 1.939–5.761) were factors associated with increased risk of infection by intestinal parasites or enteric bacterial pathogens. All Salmonella and Shigella isolates were 100% resistant to ampicillin. Conclusion The infection with intestinal parasites and enteric bacterial pathogens detected in this study indicated that street food handlers may serve as sources of pathogens/parasites for transmission and experience morbidities due to the infections. Therefore, periodic medical checkups and creating awareness of personal hygiene are mandatory to reduce the risk of infections.

Abstract
Monitoring of pathogenic bacteria plays a vital role in precluding foodborne disease outbreaks. In this research work, a genosensor based on innovative label-free DNA was developed for the detection of Salmonella. typhimurium (S. typhimurium) in the milk samples. To realize this objective, bimetallic Fe/Mn MOF is synthesized and mixed with methyl-β-cyclodextrin (MβCD) and AuNPs which are then stabilized on multi-walled carbon nanotubes (MWCNTs), and the obtained nanocomposite is immobilized on the Au electrode surface. Different characterization methods such as FE-SEM, TEM, EDS, FTIR, and XRD were used for investigating the particle size and morphological features. Electrochemical and impedimetric techniques were used for exploring the applicability of the fabricated genosensor. Under optimal circumstances, LOD and LOQ have acquired at 0.07 pM and 0.21 pM. Moreover, an extensive linear range of 1 pM-1 μM was resulted for ss-tDNA (single-stranded target DNA), R2 obtained 0.9991. The recoveries were obtained 95.6-104%. Great selectivity against one, two, and three-base mismatched sequences was also shown for fabricated biosensing assay. Furthermore, negative genosensing assay control for investigating selectivity was provided by the ss-tDNAs of Haemophilusinfluenzae and Shigella dysenteriae bacteria. Well-fabricated genosensing bio-assay represents better performance, great specificity, high sensitivity, increased active sites, and finally results in an increase in the electron transfer rate. It is to be noted that the organized genosensing bio-assay is capable of being re-used and re-generated in a straightforward manner to estimate the hybridization process.

Abstract
Bacterial Foodborne Pathogens (FBP) are the commonest cause of foodborne illness or foodborne diseases (FBD) worldwide. They contaminate food at any stages in the entire food chain, from farm to dining-table. Among these, the Diarrheagenic Escherichia coli (DEC), Non typhoidal Salmonella (NTS), Shigella spp. and Campylobacter spp. are responsible for a large proportion of illnesses, deaths; and, particularly, as causes of acute diarrheal diseases. Though existing studies indicate the problem may be severe in developing countries like Ethiopia, the evidence is commonly based on fragmented data from individual studies. A review of published and unpublished manuscripts was conducted to obtain information on major FBP and identify the gaps in tracking their source attributions at the human, animal and environmental interface. A total of 1753 articles were initially retrieved after restricting the study period to between January 2000 and July 2020. After the second screening, only 51 articles on the humans and 43 on the environmental sample based studies were included in this review. In the absence of subgroups, overall as well as human stool and environmental sample based pooled prevalence estimate of FBP were analyzed. Since, substantial heterogeneity is expected, we also performed a subgroup analyses for principal study variables to estimate pooled prevalence of FBP at different epidemiological settings in both sample sources. The overall random pooled prevalence estimate of FBP (Salmonella, pathogenic Escherichia coli (E. coli), Shigella and Campylobacter spp.) was 8%; 95% CI: 6.5-8.7, with statistically higher (P < 0.01) estimates in environmental samples (11%) than in human stool (6%). The subgroup analysis depicted that Salmonella and pathogenic E. coli contributed to 5.7% (95% CI: 4.7-6.8) and 11.6% (95% CI: 8.8-15.1) respectively, of the overall pooled prevalence estimates of FBD in Ethiopia. The result of meta-regression showed, administrative regional state, geographic area of the study, source of sample and categorized sample size all significantly contributed to the heterogeneity of Salmonella and pathogenic E. coli estimates. Besides, the multivariate meta- regression indicated the actual study year between 2011 and 2015 was significantly associated with the environmental sample-based prevalence estimates of these FBP. This systematic review and meta-analysis depicted FBP are important in Ethiopia though majority of the studies were conducted separately either in human, animal or environmental samples employing routine culture based diagnostic method. Thus, further FBD study at the human, animal and environmental interface employing advanced diagnostic methods is needed to investigate source attributions of FBD in one health approach.

Abstract
OBJECTIVES Carbapenem-resistant Enterobacteriaceae (CRE) have become one of the most challenging problems in infectious diseases worldwide. Unrecognised personnel such as food handlers (FHs) colonised with CRE serve as a reservoir for transmission. This study assessed the prevalence and susceptibility patterns of CRE isolates from FHs working in commercial eateries in the community (CFHs) and healthcare settings (HCFHs) in Kuwait over the period 2016-2018. METHODS Representative colonies from faecal samples were identified by API 20E and a VITEK®2 ID System. Susceptibility testing against 21 antibiotics was performed by Etest and agar dilution. RESULTS A total of 681 isolates of the family Enterobacteriaceae were isolated from 405 FHs, of which 425 (62.4%) were Escherichia coli and 126 (18.5%) were Klebsiella pneumoniae. The prevalence of CRE among FHs was 7.7% (31/405), comprising 32% CFHs (10/31) and 68% HCFHs (21/31). Ampicillin, tetracycline and cefalotin showed very poor activities against most isolates with resistance rates of 63.3%, 41.7% and 40.8%, respectively. The prevalence of multidrug-resistant (MDR) isolates was 30.5%, including 130 E. coli (30.6%) and 22 K. pneumoniae (17.5%). An alarming level of colistin resistance (11.3%) was noted. A significant proportion of FH isolates (13.2%) exhibited extended-spectrum β-lactamases (ESBL) phenotypes, including 80 E. coli (18.8%) and 5 K. pneumoniae (4.0%). CONCLUSION This study revealed that asymptomatic intestinal carriage of CRE, including MDR and ESBL isolates, was relatively common in our community. It is conceivable that FHs may pose a significant risk to consumers for the acquisition and spread of resistant strains.

Abstract
Concurrent infection with Schistosoma mansoni and Salmonella species is not uncommon in the endemic area of sub-Saharan Africa, although its prevalence may have regional variations. We discuss such coinfection and associated factors in an Ethiopian context. We assessed the prevalence of S. mansoni and Salmonella coinfections among patients attending two hospitals in southern Ethiopia. A facility-based cross-sectional study was carried out between 1 October and 30 November 2019. In total 271 participants with gastrointestinal complaints were selected through a systematic sampling technique. S. mansoni was detected using direct microscopy and formalin-ether concentration techniques, whereas Salmonella was identified by conventional culture methods and the Widal test. Antibiotic susceptibility test for Salmonella isolates was performed. The prevalence rates of S. mansoni and Salmonella infections were 17.30% and 7.70% respectively. The prevalence of S. mansoni-Salmonella coinfection was 7.7%. Of the factors analysed in connection with coinfection, male sex, age and frequency of exposure to contaminated water bodies were found to be statistically significant. S. mansoni-Salmonella coinfections pose a grave health problem in the study area, especially among children. Our conclusions can be used by the medical community to frame and implement intervention strategies for the management of S. mansoni-Salmonella coinfections.

Abstract
Introduction Food hygiene is an essential matter of public health for protecting or preventing diseases caused by unsafe food due to lack of good quality from production to consumption. Objective The current study aimed at assessing the food hygiene practice and determinant factors among food handlers working at the University of Gondar. Methods Univariate and multivariable binary logistic regression analyses were used to test the association of covariates with the food safety practice. Variables with p-value <0.2 were candidates for multivariable analysis. The adjusted odds ratio with 95% confidence interval and p-values less than 0.05 were used to report associations in the final model. Results A total of 184(46.7%) of the study subjects had good self-reported food hygiene practice. Being male [Adjusted odds ratio (AOR): 2.37, 95% confidence interval (CI) (1.34, 4.19)], educational status (primary [AOR: 2.54, 95% CI (1.16, 5.58)] and secondary [AOR: 2.20, 95% CI (1.11, 4.37)]), workers with greater than 2 years work experience [AOR: 1.86, 95% CI (1.06, 3.25)], monthly income of 2044–4867ETB/month [AOR: 2.05, 95% CI (1.01, 4.16)] were independent predictors of food safety practice of food handlers. Conclusion and Recommendations Below half of the study subjects had good self-reported food hygiene practice. Sex, educational status, and income were factors associated with the food hygiene practice. There should be continuous supportive supervision to raise the skills of food handlers to comply to better food hygiene practice. Food hygiene training should be given especially to female food handlers. Frequent audits are also required to ensure the permanence of effective and continuous training. Regular medical check up and strict hygiene follow-up should be encouraged to prevent foodborne disease outbreaks at universities.

Abstract
Background Unsafe food becomes a global public health and economic threat to humans. The health status, personal hygiene, knowledge, and practice of food handlers have crucial impact on food contamination. Hence, this study is aimed at assessing the knowledge, practice, and prevalence of Salmonella, Shigella, and intestinal parasites among food handlers in Eastern Tigrai prison centers, Northern Ethiopia. Methods An institutional-based cross-sectional study was carried out from April to September 2019 among food handlers in Eastern Tigrai prison centers, Northern Ethiopia. A structured questionnaire was used to collect the demographic characteristics, the knowledge, and the practice of the study participants. Direct wet mount and formol-ether concentration techniques were applied to identify intestinal parasites. Culture and biochemical tests were used to isolate the Salmonella and the Shigella species. Additionally, antimicrobial susceptibility tests to selected antibiotics were performed using Kirby-Baur disk diffusion method. We used SPSS version 23 software for statistical analysis. Results Thirty-seven (62.7%, 37/59) of the participants had harbored one or more intestinal parasites. The protozoan Entamoeba histolytica/dispar was detected among 23.7% (14/59) of the study participants who provided stool specimen. Besides, 6.8% (4/59) of the samples were positive for either Salmonella or Shigella species. The Salmonella isolates (n = 2) were sensitive to Gentamicin, Ciprofloxacin, Ceftriaxone, and Clarithromycin but resistant to Amoxicillin, Ampicillin, and Amoxicillin/clavulanic acid. Similarly, the two Shigella isolates were susceptible to Gentamicin, Ciprofloxacin, and Ceftriaxone but showed resistance to Amoxicillin, Tetracycline, and Chloramphenicol. Further, 60.6% (40/66) of the participants had good level of knowledge, and 51.5% (34/66) had good level of practice on foodborne diseases and on food safety. Conclusions We conclude that foodborne pathogens are significant health problems in the study areas. Regular health education and training programs among the food handlers are demanded to tackle foodborne diseases at the prison centers.

Abstract
2-Isopropylmalic acid (2-IPMA) and 3-isopropylmalic acid (3-IPMA), recently discovered in wines, were simultaneously quantified in forty wines by UHPLC-MS/MS triple quadrupole. Principal component analysis displayed that red wines were more correlated with high amounts of 2-IPMA (average content 31.60 mg/L); white wines were mostly characterized by low levels of both organic acids. No correlation of theirs levels to other wine features (wine ageing or alcoholic content) were found. 2-IPMA and 3-IPMA showed MICs values of 4096 mg/L and MBCs values of 8192 mg/L or higher against several food borne pathogens. In association, an interesting lower MIC and MBC values (2048 mg/L and 4096 mg/L respectively) were observed against Y. enterocolitica. Interestingly, 3-IPMA showed a mild antioxidant activity by DPPH assay (EC50 = 3940 mg/L), higher than that of 2-IPMA (EC50 > 4800 mg/L). No toxicity of these compounds against human colorectal and liver cells (TB assay) was observed.

Abstract
BACKGROUND Shigella species are a major cause of dysentery and may attribute for death worldwide. Currently antibiotic resistance became the critical challenges for management of infectious disease. The aim was to conduct a systematic review and meta-analysis of Shigella species and its drug resistance pattern in Ethiopia. METHODS A comprehensive literature search was conducted through internet searches using database of MEDLINE, PubMed, Google scholar, EMBASE, HINARI, Cochrane Library and reference lists of previous prevalence studies from January 1999 to November 2018. Results were presented in forest plot, tables and figures with 95% CI. The Cochrane Q test and I2 test statistic were used to test heterogeneity across studies. The Pooled estimate of Shigella species and its drug resistance pattern was computed by a random effects model. RESULTS The pooled prevalence of Shigella species in Ethiopia was 6.6% (95% CI 4.7-8.8). In the subgroup analysis, the highest prevalence was observed among patients in Health facility (8.5%, 95% CI 6.2-11.5) whereas the lowest prevalence was observed in Community based studies (1.6%, 95% CI 0.8-3.4). In addition, Shigella species were highly resistant to ampicillin, amoxicillin, erythromycin and multi-drug resistant (MDR) with the pooled resistance proportions of 83.1% (95% CI 75.7-88.6), 84.1% (95% CI 75.6-90.1), 86.5% (95% CI 70.9-94.4) and 83.2% (95% CI 77.1-87.9), respectively. On the other hand, comparably low resistance pattern was reported for ciprofloxacin 8.9% (95% CI 6.0-12.8), ceftriaxone 9.3% (95% CI 3.9-20.5), and norfloxacin 8.2% (95% CI 3.8-16.6) and gentamycin 17.3% (95% CI 11.2-25.9). Subgroup analyses indicated that study years were associated with a decreasing Shigella prevalence over time (p = 0.002). CONCLUSION The pooled estimate showed high burden of Shigella infection and its high proportion of drug resistance pattern to ampicillin, amoxicillin and erythromycin in Ethiopia. Therefore, initiating and scale up of performing drug susceptibility test for each shigellosis case, educate the community and health care providers on appropriate use of antibiotics need to be considered and strengthened.

Abstract
BACKGROUND Salmonella and Shigella infections are a common public health problem throughout the world. The risk of getting infections is high, where asymptomatic street food vendors are preparing foods and vending. Current knowledge of antimicrobial susceptibility pattern is essential for appropriate treatment and management of these infections. OBJECTIVE This study was aimed to determine the prevalence, antimicrobial susceptibility pattern, and associated factors of Salmonella and Shigella among asymptomatic street food vendors in the Dire Dawa city, Eastern Ethiopia. METHODS A cross-sectional study was conducted among 218 randomly selected asymptomatic street food vendors in the Dire Dawa city, Eastern Ethiopia from May to July 2017. Data on the sociodemographic and associated factors were collected using a pretested structured questionnaire. The stool specimens collected were examined for Salmonella and Shigella using recommended culture methods. The antimicrobial susceptibility test was done using the disk diffusion technique. Data were described using descriptive statistical tools. Logistic regression models were used to identify the factors associated with Salmonella and Shigella infections. A P-value ⩽ .05 was considered statistically significant. RESULTS The overall prevalence of Salmonella and Shigella was 8.7% (95% confidence interval: 5.6, 10.3). The most common isolates were Salmonella (6%). Most of the isolates were resistant to amoxicillin (97.7%), ampicillin (89.5%), and tetracycline (68.4%). Almost half (47.4%) of Salmonella isolates were multidrug resistant. Food vendors who did not wash hands with soap after the use of the toilet (adjusted odds ratio: 3.3, 95% confidence interval: 1.2, 7.9), and who had untrimmed fingernails (adjusted odds ratio: 4.4, 95% confidence interval: 1.5, 9.3) had higher odds of Salmonella and Shigella compared with their counterparts. CONCLUSIONS The carrier rate of Salmonella and Shigella was relatively low. Most isolates have developed resistance to amoxicillin, ampicillin, and tetracycline. The odds of Salmonella and Shigella was high among those who lack a habit of hand washing with soap after the use of the toilet and with untrimmed fingernails. Regular screening and appropriate hygienic control measures are needed in place to reduce the risk of infections.

Abstract
BACKGROUND Food handlers with untrimmed finger nails could contribute or serve as a vehicle for the transmission of food poisoning pathogens. OBJECTIVES This study was conducted to determine the prevalence of bacteria and intestinal parasites among food handlers and antibiotic susceptibility profile of the isolated bacteria in Debre Markos University, Ethiopia. MATERIALS AND METHODS This laboratory-based cross-sectional study involved 220 food handlers working in food service establishments in Debre Markos University between 1st January 2015 to 31th June 2016. Subjects' finger nail specimens of both hands were examined microscopically for intestinal parasites. For bacterial isolation, samples were cultured and bacterial species were identified following standard laboratory procedures. Antimicrobial susceptibility test was performed for all bacterial isolates by using Kirby-Bauer disk diffusion method. RESULTS Of the total 220 subjects examined, 29.5% showed positive culture for different bacterial species from their fingernail contents. Coagulase-negative Staphylococcus was the predominant bacteria species (12.3%) followed by Staphylococcus aureus (5%), E. coli (2.7%), Klebsiella species (2.7%), Enterococcus species (1.8%), Pseudomonas aeruginosa (1.8%), Proteus species (1.4%), Citrobacter species (1.4%), and Serratia species (0.9%). None of the food handlers showed positive culture for Shigella and salmonella and parasites in respect of their finger nail specimens. Isolation of bacteria in finger nail has significant association with finger nail status (P=0.044) and inverse relation with service years (P=0.048). All Staphylococcus aureus and coagulase-negative Staphylococcus species isolates were uniformly susceptible to vancomycin. Only one (9.1%) of Staphylococcus aureus isolates was resistant for methicillin. CONCLUSION To prevent the food poisoning pathogens, implementation and adherence to infection are the key practices, specially food handlers with long finger nail harbor food debris, microbial contaminations, and allergens.
