A cross-sectional survey was conducted to determine the prevalence of Blastocystis hominis infection in a random sample of apparently healthy food handlers. A total of 250 individuals attending a primary health care unit in Shibin El Kom, Menoufiya governorate, Egypt and who requested health certification to work as food handlers were studied. A stool sample was obtained and examined by direct microscopy. A total of 150 individuals were infected with intestinal parasites (60%), 116 (46.4%) of whom were infected with B. hominis. There was no difference between males and females (p > 0.05), but there was a significant difference between ages, with infection more frequent between 20 and 30 years. In 70.7% (82 out of 116) of the cases, B. hominis was the only parasite. Giardia lamblia was the parasite most frequently associated with B. hominis (14.7%). In the majority (85%) of infected individuals, less than five microorganisms per microscopic field were observed. We conclude that B. hominis is a frequent intestinal parasite among food handlers in Menoufyia Governorate.
