title: Frequency of intestinal parasites among food-handlers in Khartoum, Sudan.
abstract: Food-handlers (n = 1500) attending the public health laboratory in Khartoum, Sudan, for annual check-ups were screened for intestinal parasites by 3 different techniques (direct faecal examination, formol-ether concentration and floatation) to evaluate the adequacy of annual screening. Results showed that 29.4% of food-handlers were harbouring intestinal protozoa in stool samples: Entamoeba coli in 15.3%, Giardia lamblia in 9.7%, and Enta. histolytica in 4.3%. Moreover, 2.7% of food-handlers harboured intestinal helminths: Hymenolepis nana (1.6%), Schistosoma mansoni (0.7%), Taenia saginata (0.3%) and Strongyloides stercoralis (0.1%). We recommend more frequent screening of food-handlers and that the direct faecal smear technique is efficient for the detection of such parasites.
