Abstract: An attempt was made to study the possible sources of transmission of protozoan cysts and helminthe eggs to man in the Samastipur town of Bihar from media such as soil, water and raw edibles (vegetables & fruits). A total of 2091 samples comprising 402 soil samples, 526 water samples, 375 fruit samples and 788 vegetables samples were examined. The highest prevalence rate (30.6 percent) was observed in soil samples and the lowest (12.05 percent) in vegetable samples. Out of the contaminated samples, 5.93 percent, 4.02 percent, 9.90 percent were position for Entamoeba histolytica, Giardia intestinalis and Ascaris lumbricoides respectively.
