title: Control of helminth contamination of raw vegetables by washing.
abstract: This study was conducted to determine the control of helminth egg contamination of raw vegetables by washing. A total of 199 unwashed and 199 washed lettuce, parsley, carrots, dill, rocket, and green-peppers, provided by a catering service in Bursa, Turkey, between March and June 2009, were subjected to helminth egg count under light microscopy. Helminth eggs were detected in six (3.0%) unwashed samples and not in any washed samples (p<0.01). Ascaris lumbricoides and Toxocara spp. were detected in four (2.0%) and two (1.0%) unwashed vegetables, respectively, mostly among leafy vegetables such as lettuce and parsley. Our data confirm that washing procedures before consumption of raw vegetables regardless of the providers' sanitation should be performed to avoid transmission of helminths.
