“…The finding is comparable to a study conducted in Addis Ababa University, Ethiopia (3.4%) [19]; but relatively higher than reports from other parts of Ethiopia, such as Dilla University (0.93%) [8] and Mekelle University (1%) [12]. However, it is lower compared with a study done in Arba Minch University, Southern Ethiopia (6.9%) [20] and Bahir Dar, Ethiopia (80%) [4].…”

ObjectiveSalmonellosis and Shigellosis remain a major public health problem across the globe, particularly in developing countries like Ethiopia, where hand hygiene and food microbiology are still below the required standards. The growing problem of antimicrobial resistance species also continues to pose public health challenges. This study assessed the prevalence and antimicrobial susceptibility pattern of Salmonella and Shigella species among asymptomatic food handlers. A cross-sectional study was conducted among 417 randomly selected asymptomatic food handlers. Data were collected using a structured questionnaire. The stool specimens collected were examined for Salmonella and Shigella species using standard bacteriological methods. Descriptive statistics were used to describe the basic features of the data.ResultsThe overall prevalence of Salmonella and Shigella species was 5.04%. Salmonella and Shigella species were 76.2% resistant to both co-trimoxazole and tetracycline, 71.4% to amoxicillin and 66.7% to chloramphenicol. Moreover, 85.7% of Salmonella and Shigella species were multidrug resistant. The findings highlighted the food handlers as potential sources of food borne infections, which demands the establishment of appropriate hygiene and sanitary control measures at the University cafeterias.

“…In a study by Aluko et al (2014), only 22.5% of the handlers underwent medical examination in the laboratory to ensure that they were free of foodborne diseases before starting handling of food. Gebreyesus et al (2014) reported contamination of food handlers by parasites. The authors believe that such results can be related to health certificates that are valid for more than six months, a lack of basic safety requirements and healthy food, and inadequate personal hygiene.…”

ABSTRACT:This study was conducted jointly with the Municipal Sanitary Surveillance Agency of Petrolina, in the period of August-October 2013, to evaluate the hygienic-sanitary conditions of food producing and commercializing establishments in the municipality of Petrolina. A total of 300 food manufacturer/trader establishments were evaluated based on a Good Manufacturing Practices (GMP) checklist. The evaluation was based on 25 items. The data were computed as 0 for nonconformity and 1 for conformity to the GMP checklist. Data from all districts were analyzed by Principal Component Analysis (PCA). Items such as presence of lamp protectors, clean windows and screens, presence of SOP and training programs for handlers, use of aprons, caps, gloves and disposable towels, and performing periodic examinations of the establishments were evaluated. Fourteen evaluation items showed significant differences (P<0.05) for frequency of conforming and 9 for nonconforming. The PCA identified five city districts (Centro Norte, Areia Branca, Santa Luzia, Rio Corrente and São Gonçalo) in the municipality that used GMP in their establishments. These results highlight the need to redouble efforts in establishments to ensure the safety of products offered.

“…Transmission of Salmonella is usually the result of poor hygiene during food handling with approximately 70% of diarrheal diseases being the result of contaminated food in the developing world [13], [14]. Improper handwashing after using toilet facilities, lack of education for handling food and cross contamination are all identified sources of likely salmonella transmission [6].…”

“…Animal sources are the most common source of NTS which is carried in the intestinal tract of food animals, intestinal contents of NTS infected animals often times contaminate the meat during the butchering process and is spread to food preparation surfaces and utensils [15]. Typhoidal salmonella has very few animal hosts and is the result of fecal-oral transmission of the bacteria from person-to-person [14]. Additionally, asymptomatic carriers of NTS and typhoidal Salmonella continue to shed bacteria in their feces and urine providing an opportune pathway of infection for the pathogen [14].…”

Abstract:Background: Salmonella spp are among the most common food borne pathogens. Food handlers play an important role in the production of food products, in which they can contribute to the transmission of salmonellosis. The probability of food contamination depends mainly on the health status and personal hygiene of the food handlers and their choice of managing their health could give rise to contamination of food by multi drug resistant bacteria. Multi Drug Resistance is of global concern and poses a public health threat in combating diseases. In the developing countries there is paucity on the prevalence of salmonella carriage among food handlers. This study aims to investigate the prevalence of salmonella and to determine their antimicrobial resistance pattern. Method: A total of 500 stool samples from different food handlers were collected and analyzed with completed questionnaires. For standard isolation and identification of salmonella isolates; stool samples were enriched in buffered peptone water, standard culture and biochemical tests were used. Antimicrobial susceptibility Test (AST) was carried out using Clinical Laboratory and Standard Institute (CLSI-2015) protocol disc diffusion method. The data were analyzed using SPSS version 16 and Microsoft excel version 2010 to determine the risk factors. Results: Of 500 participants with the mean age of 38.15, 497(99.4%) were all females. Most of the participants wash their hands under running water and 271(54.2%) were certified on food handling. Among the risk factors, consuming medicines/antibiotics from street vendors showed statistical significant of salmonella carriage with (P=0.011). It was found that 13(2.6%) were salmonella carriers. AST performed on the 13 isolates show that; 13(100%), 12(92.3%), 7(53.8%), 9(69.2%) and 9(69.2%) were resistant to Ampicillin, Erythromycin, and Tetracycline, ceftriaxone and cefotaxime respectively. And 13(100%), 12(92.3%) and 7(53.8) were sensitive to Imipenem, chloramphenicol and gentamycin respectively. Conclusion: This study had found multidrug resistant salmonella isolates carriers amongst food handlers who could serve as potential reservoirs for the transmission of these infections in the communities. Thus, it is crucial to implement regular screening of food handlers and health education on food safety.
