“…In Irbid, Jordan [3], out of 283 food-handlers screened, 17 (6%) were Salmonella carriers. In Ghana [12], 258 asymptomatic food vendors were screened and Salmonella was isolated from 6 (2.3%). In India [5], among 35 individuals screened 6 (17.14%) were positive for Salmonella.…”

Abstract:Background: Salmonella is the most frequently reported cause of food borne illness in Ethiopia. Objective: The aim of this study was to screen food handlers in the Dilla area of Southern Ethiopia and to assess the scale of carriage of Salmonella species and to offer prophylaxis followed by re-testing and advice on personal and food hygiene as appropriate. Method: Stool samples were collected from a total of 107 food handlers from various establishments in the area. Enrichment culture using Selenite broth and sub-culture on to Deoxycholate Citrate agar was used followed by identification to genus level by use of a commercially available biochemical kit and polyvalent antisera. Result: Salmonella was isolated from one food handler only and this person could not be traced having left her employment and not having left a forwarding address. Conclusion: As food poisoning is a main issue in Ethiopia further epidemiological research, to monitor those found to be infected is mandatory.

“…Moreover, Yismaw G et al reported that 79.2% and 44.1%of S. typhi isolated from clinical samples in Gondar University hospital were resistant to chloramphenicol and gentamicine respectively (9). Studies had demonstrated that food handlers harbour S. typhi asymptomatically (10)(11)(12).…”

Background: Food borne diseases are a global public health problem. Food handlers play a major role for the transmission of food borne diseases. Objectives: This study was aimed at exploring the prevalence of intestinal parasites, S. typhi carrier rate and risk factors among food handlers at Bahir Dar town. Methods: A cross -sectional survey was conducted among food handlers working in different kitchens. A pre-tested structured questionnaire was used for collecting data. Stool samples were investigated for intestinal parasites and S. typhi as per the standard laboratory methods. Results: Among 384 food handlers, females comprised 300 (78%). The majority 371 (96.6%) were young adults (12-40 years). The median year of service was 1 year (1 month to 24 years). All food handlers had no previous medical checkup and 54 (14%) were certified as food handlers. One hundred fifty eight (41.1%) food handlers had intestinal parasites and 6 (1.6%) were found positive for S. typhi. Of these, 25 (6.5%) were suffering from diarrhoea. Nine species of intestinal parasites, 2 protozoa (E. histolytica/dispar 12.76% and G. lamblia 7. 0%) and 7 helminthes (A. lumbricoides, 11.7%, Hookworm, 8.1%, S. stercoralis, 2.86%, S. mansoni, 1.8%, Taenia species, 1.3%, H. nana, 0.5% and T. trichiuria, 0.5%) were detected. Conclusion: Inexperienced and poor personal hygienic food handlers play a role for transmission of food borne infections. Local health authorities should implement food handler's training on food safety, institute periodic focused medical check up for food handlers and improve human waste disposal. [Ethiop. J. Health Dev. 2010;24(1):46-50] IntroductionFood borne diseases are a public health problem in developed and developing countries. The World health organization (WHO) estimated that in developed countries, up to 30% of the population suffer from food borne diseases each year, whereas in developing countries up to 2 million deaths are estimated per year (1, 2).

“…One article in our study reported that food handlers constitute a significant risk in the spread of enteric fever in Kumasi [18]. This observation calls for concern because the situation could be worse in other towns where food safety education is generally lacking.…”

“…The selected articles came from the following journals: three from Acta Tropica [11][12][13], two from the Ghana Medical Journal [14,15], two from the International Journal of Microbiology [16,17], and one each from the East African Medical Journal [18], the Journal of Urban Health [19], Archives of Environmental Contamination and Toxicology [20], and the Bulletin of the World Health Organization [21]. Published studies on food safety were observed to have mainly been based on research performed in the southern half of the country, with the majority of publications coming from the capital Accra and its environs ( Figure 1).…”

Introduction: Food safety is a crucial factor in the growth of developing countries worldwide. In this study, we present a meta-analysis of microbiological food safety publications from Ghana. Methodology: The search words "Ghana food safety", "Ghana food research", and "Ghana food bacteria" were used to search for microbiological food safety publications with related abstracts or titles in PubMed, published between 1997 and 2009. We obtained 183 research articles, from which we excluded articles concerning ready-to-eat microbial fermented foods and waterborne microorganisms as well as articles without abstracts. The criteria used for analysis of these publications were based on an assessment of methodological soundness previously developed for use in the medical field, with some modifications incorporated. Results: The most predominant bacteria in Ghanain foods are Enterobacter spp., Citrobacter spp., Klebsiella spp. and Escherichia spp., which were found to be present in 65%, 50%, 46% and 38% respectively, of the food samples considered in the studies analysed. The most contaminated food samples were macaroni, salad, and milk. Although the methodological quality of the articles was generally sound, most of them did not give directions for future research. Several did not state possible reasons for differences between studies. Conclusion: The microbiological food contamination in Ghana is alarming. However, we found that the downward trend in publications of microbial food safety articles is appalling. Hence a concerted effort in research on food safety is needed in Ghana to help curb the incidence of preventable food-borne disease.
