Title: Salmonella Carriers Among Public Food Handlers In Khartoum Municipality
Author: Hamedto, Hisham
Abstract: Enteric fever is a public health problem primarily in endemic countries, where carriers, convalescent and sick persons spread the enteric bacilli widely. The development of a permanent carrier state is an important event in the life cycle of enteric fever bacilli. Our study was conducted to screen the prevalence of Salmonella carriers among food handlers working in food services establishments located in various areas of Khartoum municipality during the period from Feb to August 2006. A total of 5493 food handlers were investigated during this study, regarding their sociodemographic, professional characteristics, and their hand washing practices were also observed. Stool cultures for the isolation of Salmonella were carried out by direct plating or after enrichment in two selective classical media (SS agar and XLD agar media). Only Salmonella entericaserotype Paratyphi B was isolated from 17 subjects during February, March & May. Peak of isolation was registered in March (47.05%). Only two isolates (11.8 %) of Salmonella Paratyphi B were recovered by direct plating on XLD and S.S. agar media and 15 isolates (88.2 %) were recovered following enrichment on Selenite-F broth. All isolates were identified to species level using culture characteristics and biochemical reactions and confirmed serologically. S.S. agarand XLD media were found to be satisfactory for isolation of Salmonella from stool samples of food handlers with the view we could optimize our routine protocol and to assess food handlers bacteriologically with the minimum amount of 5 work and cost. Salmonella Paratyphi B was isolated from food handlers working in various area studies, six carriers were detected at Al Soug Al Mahali and Al Soug Al Markazi (35.3 %) as well as other areas including Khartoum-2 and Riyadh areas. Fifteenisolates were recovered from males (88.2 %) and only two from female subjects (11.8 %). High prevalence of infection was recorded among restaurateurs (58.8 %), hence sound Kitchen hygiene is essential for the prevention of Salmonella infection and this apply equally to commercially and house-hold kitchens. This study has revealeda poor knowledge and practices of food hygiene among food handlers and we recommend a massive health education campaign directed at both the public and food handlers be embarked on, to enable people to take necessary steps to prevent food- borne diseases complementary to strict governmental regulations empowerment as food handlers play an important role in maintaining the endemicity of Salmonella infection in the community.
