Food borne diseases are a global public health burden. Food handlers play a major role in the transmission of foodborne diseases. This study was aimed at investigating the presence of intestinal parasites, S. typhi carrier rate and associated risk factors among food handlers in a metropolitan city. MATERIALS AND METHODSA cross-sectional survey was conducted among 200 food handlers working in different food service establishments. A pre-tested structured questionnaire was used to collect data on age, sex, years of service, previous deworming, status of typhoid immunization and hand washing practices. Stool samples were processed for intestinal parasites and S. typhi, as per the standard laboratory methods. RESULTSIn the present study, majority of the food handlers were males 185/200 (92.5%), 90/200 (45%) were aged between 30-50 years, and 72/200 (36%) had less than one year experience. Intestinal parasites were detected in 31/200 (15.5%) and S. typhi in 2 (1%). Of the 31 parasites, 11 (35.5%) were seen by direct saline technique and additional 20 (64.5%) by formol-ether concentration technique. The parasites found in descending order of frequency among the food handlers were: fertilized eggs of Ascaris lumbricoides 8.5% (17/200), cyst of Giardia (3.5%), cyst of Entamoeba histolytica 2% (4/200), eggs of Taenia spp. 1% (2/200) and eggs of Trichuris trichiura 0.5% (1/200). The association of years of work experience was inversely proportional to parasitic infection and directly proportional to history of previous deworming, both of which were statistically significant. CONCLUSIONInexperience and lack of awareness about hygiene in food handlers play a major role in the transmission of food-borne infections. Training on food safety and periodic focused medical check-up can help to control the spread of infection in the community. Laboratory investigation should include formol ether concentration technique to enhance diagnosis.

Abstract:Background: Shigellosis and salmonellosis are still global health problems, especially, in developing countries where poor sanitation, lack of clean water supply and proper sewage disposal system exist. The emergence of increased antimicrobial resistance of Shigella and Salmonella species are global challenges, particularly in developing countries like Ethiopia where increased misuse of antimicrobial agents by human beings occur. Objectives: To determine the prevalence and antimicrobial susceptibility patterns of Shigella and Salmonella isolates from patients with diarrhea attending the health institutions in Gondar town, Northwest Ethiopia. Materials and Methods: Health institutional based cross sectional study was carried out on diarrheic patients attending Gondar town health institutions, February 29, 2014 to May 20, 2014. Systematic random sampling technique was used and stool samples were collected from 372 study subjects. Samples were cultured onto MacConkey and Salmonella-Shigella agars and drug susceptibility patterns of the isolates were determined following standard bacteriological method. Data were coded and entered for statistical analysis using SPSS version 20. Data were presented using tables and chi-square. Result: Of the total of 372 stool cultures, 17(4.57%) Shigella spp. and 4(1.08%) Salmonella spp. were isolated. Most commonly isolated strains of Shigella were S. flexneri 11(64.7%) followed by S. dysenteriae 3(17.65%), S. boydii 2(11.77%) and S. sonnei 1(5.88%). Shigella isolates presented high resistance rate to ampicilin (94.1%), amoxicillin (88.2), tetracycline (88.2%) and Salmonella species were highly resistance to tetracycline (100%), amoxicillin (100%), and ampicillin (75%). However, all isolates of Shigella and Salmonella were 100% susceptible to ciprofloxacin and norfloxacin. Conclusion and recommendation: This study revealed that isolates of Shigella and Salmonella showed high rate of drug resistance to the commonly used antibiotics. However, all the isolates were susceptible to ciprofloxacin, and norfloxacin. Therefore, ciprofloxacin and norfloxacin can be used as drugs of choice for the treatment of Shigellosis and Salmonellosis.

BackgroundThe consumption of multidrug resistant Salmonella isolates along with a raw meat dish is directly relevant to the global public health crisis of antimicrobial resistance. All countries around the globe are suffering from food-borne diseases. In developing countries, more than one billion individuals suffering from gastroenteritis and around five million infected individuals die annually.MethodsA cross-sectional study was carried out from December 2015 to May 2016 to show the risk of Salmonella associated with consuming traditional raw meat dishes and to characterize the antimicrobial resistance profile at Wolaita Sodo municipal abattoir. Animals were being processed as part of the normal work of the abattoir, and 448 carcass samples were taken after getting a written consent from the municipality. Samples were transported to Wolaita Sodo University Microbiology Laboratory in an ice box within an hour of collection. Swab samples were pre-enriched in tetrathionate broth and Rappaport-Vassiliadis R10 broth. Broth culture was sub-cultured on xylose lysine deoxycholate and brilliant green agar and incubated at a temperature of 37 °C for overnight. Antimicrobial susceptibility test was done by disk diffusion method. Microbiological and observational data entry and analysis were done using Microsoft Excel 2007.ResultsFrom the total 448 sampled carcasses, Salmonella growth was observed in 56 (12.5%) samples. The isolates had various resistance profiles, with resistance to 1 to 12 antimicrobial drugs. Tetracycline- and nitrofurantion-resistant isolates were frequent, 83.93 and 73.21% respectively, and followed by streptomycin-resistant isolates (66%). Ciprofloxacin-resistant isolates were rare (7%).Conclusion Salmonella species contamination frequency was high in raw beef, and most of the isolates exhibited resistance to commonly used antibiotics. People living in the town and consuming the raw meat are at risk for developing diseases, and attention should be given to select antimicrobials in treating Salmonella infections in both animals and human being based on antimicrobial susceptibility test. Moreover, intersectoral working and developing one health approach is essential. Health information should be given to individuals who have the habit of eating raw meat. Training on sanitary and hygiene practice should be given to the abattoir workers.Electronic supplementary materialThe online version of this article (10.1186/s41043-017-0131-z) contains supplementary material, which is available to authorized users.
