Prevalence of bacteria (Salmonella, Shigella) and intestinal parasites among food handlers in Kerman, Iran, in 1390

Food borne diseases are an important public health problem in different countries. Food handlers with poor personal hygiene working in food establishments can have an important role in the transmission of these diseases. This study was undertaken to determine the prevalence of bacteria (Salmonella, Shigella) and intestinal parasites among food handlers in the city of Kerman. This cross-sectional study in years 2011-12 was conducted. 450-food handlers were employed in the kitchen preparing food centers. We recourse to food centers and stool sample were taken in three different time from each person and samples were studied by direct observation and formalin-ether concentration method for intestinal parasites and culture for detected bacteria (Salmonella and Shigella). At the same time, a questionnaire were with variables such sex, age, education, use gloves and form, restroom and health cart filled. The data analyzed by statistical software SPSS. Among 450 food handlers, included females 40.4% and male 59.6%. The prevalence of intestinal parasites is 14.7% that 13.8% were infected with 1 parasite and 0.9% showed infection to 2 parasites. The highest prevalence is related to Giardia lamblia 7.3%, Entamoba coli 3.6%, Heminolopis nana 1.6%. There was no significant effect between age and sex with parasitic infection (Ρ=0.087 and Ρ=0.054, repectively). Whereas, using the protective facilities (gloves and uniforms) and having health cart, both significantly reduced the parasitic infection (P=0.016 and P<0.001, respectively). The Shigella isolated from 3 (0.7%) cultures and Salmonella isolated from 1 (0.2%) culture. The results show that the prevalence of intestinal parasitic infections are relatively high, especially pathogenic protozoa in food handler. Therefore, health controls should be increased and screening with concentration method should be done. It is natural in this context, the continuation and expansion of health education has a crucial role.
