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.
本研究旨在确定通过清洗来控制生蔬菜中寄生虫卵的污染。2009 年 3 月至 6 月期间，从土耳其布尔萨的一家餐饮服务提供商处收集了 199 份未清洗和 199 份已清洗的生菜、欧芹、胡萝卜、莳萝、火箭菜和青椒，并在光镜下对其进行寄生虫卵计数。在 6 份未清洗的样本中检测到了寄生虫卵，而在任何已清洗的样本中均未检测到（p<0.01）。在未清洗的蔬菜中分别检测到了 4 份（2.0%）和 2 份（1.0%）的蛔虫和旋毛虫，主要是在生菜和欧芹等叶菜中。我们的数据证实，无论供应商的卫生条件如何，在食用生蔬菜之前都应进行清洗程序，以避免寄生虫的传播。
