“…But this ampicillin resistance pattern of Salmonella isolated during this study was lower from reports that indicated 100% [ 15 ] and 82.3% [ 24 ] resistance in Addis Ababa isolated from dairy farm attendant and pediatric patients, respectively. Furthermore; the current result was lower than 87.5%, 100%, and 91.8% of ampicillin resistant Salmonella isolates reported from Addis Ababa [ 12 ], Bahir Dar [ 25 ] and Tamil Nadu [ 26 ], respectively.…”

BackgroundSalmonella species are among the most common food borne pathogens worldwide and their infection is one of the major global public health problems. During the last decade, multidrug-resistant Salmonella species have increased to a great deal, especially in developing countries. The prevalence and antimicrobial susceptibility pattern of Salmonella isolates among food handlers at the University of Gondar, Ethiopia, were described in the current investigation.MethodA cross-sectional study was conducted from February to June, 2013 at the University of Gondar. Stool samples from selected volunteer food handlers were collected and analyzed complemented with questionnaire. Standard isolation, identification and biochemical tests were performed to identify Salmonella isolates. Antimicrobial susceptibility tests were also carried out on each isolate using Kirby-Bauer disc diffusion method. The data was entered into Epi info version 3.5.4 and analyzed using SPSS version 21.ResultOut of 423 food handlers participated, 303(71.6%) were females. Almost two-third (71.4%) of food handlers had no previous medical checkup to Salmonella infection and only 24(5.7%) of them were certified as food handlers. Thirteen (3.1%) food handlers were found to be positive for Salmonella isolates. The results of antimicrobial susceptibility test in the current research revealed that from a total of 13 isolates; 9(69.2%), 8(61.5%), 6(46.2%) and 6(46.2%) of the isolates were resistant to amoxicillin, ampicillin, nitrofurantoin and tetracycline, respectively. In addition, nearly half (46.2%) of the isolates were multidrug-resistant. However; all of them were sensitive for both ceftriaxone and gentamycin.ConclusionThis study indicated that drug resistant including multidrug-resistant Salmonella isolates were circulating among food handlers at the University of Gondar. These Salmonella positive food handlers pose significant risk of infection to the university community particularly to the student population. It is essential to implement food handlers training on food safety, conduct periodic medical screening and continuous monitoring of food handlers at the study university.

“…In Bahir Dar Town (Northwest Ethiopia), 1.6% of food handlers were positive for S. typhi and 41% had intestinal parasites (Abera et al, 2010). In Namakkal (Tamilnadu, India), 20% of nail samples shows positive results of the presence of typhoid bacilli indicating that the individual (four women and one male) can harbor the typhoid bacilli without showing any symptoms of typhoid fever (Valli et al, 2010). S. aureus was present on 22.72% hands of Lomé food handlers.…”

In both developed and developing countries, street food has often been at risk of intoxication. Assessment of risk factors in this sector in Lomé could help to take appropriate measures for their control. Structured questionnaires were used to collect data from 988 street vendors while standard methods were used to search for bacteria in 270 ready-to-eat (RTE) foods sampling in Lomé. The results obtained indicate that out-of-home catering sector is mainly driven by women (96.86%). About 63% of vendors have attended primary school and 72.57% are between 25 and 54 years old. Half of the sellers (50.2%) do not have professional health card. Only one bath of soap and one bath of rinsing water are used in 56.98% of cases to wash the plates. There are no Garbage cans in 26.01% of cases. Briefly, 68.89% of the samples of RTE food analyzed were unsafe and unhygienic to good health. Total coliforms (TC), thermotolerant coliforms and Escherichia coli induced 47.03, 58.14 and 33.33% nonconformities, respectively. Staphylococcus aureus was counted in 52/270 samples but Salmonella were not detected. Food contamination level, preparation of food and sale conditions and types of water used in catering, would constitute potential risks of toxi-infection related to the consumption of street food in Lomé. Education and sensitization of the actors of the street food sector and a follow-up by the health authorities is recommended to guarantee food without major risk of poisoning in the streets of Lomé.
