Intestinal Parasitosis Among Food Handlers In The University Hospitals Of Antananarivo, Madagascar
Abstract
Introduction:Intestinal parasitic infections (IPIs) are a major public health in Madagascar. Food handlers in hospital settings may be potential sources in the transmission of intestinal parasites. The aim of this study was to estimate the prevalence of intestinal parasites and identify associated factors among food handlers in Antananarivo University Hospitals in 2018.
Methods:A descriptive analytical study was conducted. Data were collected by a pre-tested face-to-face questionnaire, supplemented by an observational control. Fresh stool samples were collected from the participants, and examined microscopically by the stool technique 3 successive times spaced 3 to 5 days apart.
Results: Of the 74 staff, the prevalence was 27.03% or 20 cases. Ascaris lumbricoides is the most encountered parasite with a rate of 37.50% (n=10), followed by T. trichiura of 29.16% (n=8), then Giardia intestinalis of 8.33% (n=2), and Ankylostoma duodenale, cysts of Endolimax nana, Entamoeba histolytica/ E.dispar, Entamoeba hartmanni were also found. No association of risk factors that could influence intestinal parasitosis was found.
Conclusion:This high prevalence of intestinal parasitosis among food handlers is of major public health importance. Routine screening for intestinal parasitosis at least once a year and good personal and food hall hygiene to ensure food safety in teaching hospitals should be realized.
