ABSTRACT

Food workers are an important risk group for intestinal parasite contamination and dissemination. In the present study food workers, working in food preparation and distribution in the Adnan Menderes University Hospital, Aydin State Hospital and 82. Yil State Hospital, were screened for the presence of intestinal parasites. Out of 58 food workers 22 were females and 36 were males, and the age of workers ranged from 20 to 56. All workers included in the study answered a questionnaire concerned with their social demographic situation and hygiene habits. Stool specimens and cellophane tape specimens were taken from food workers and studied for the presence of parasites. Stool samples were studied using native Lugol, precipitation by formol ethyl acetate, trichrome and acid fast staining methods. Cellophane tape slides were examined for Enterobius vermicularis with the 10X objective. Out of 58 food workers investigated, 17 (29.31%) had at least one parasite; nine had Blastocystis hominis (15.51%), five had E. vermicularis (8.62%), one had Giardia intestinalis (1.72%), one had both Entamoeba histolytica/dispar and Entamoeba coli (1.72%), and one had both E. vermicularis and B. hominis (1.72%). All workers with parasites were treated and taken under surveillance. The oral-fecal route is the main source for intestinal parasite contamination. It should be considered that food workers may be the main source for the contamination of hospital workers as well as patients which may cause serious problems especially for the cases with immune deficiency.
