Background. A study aimed at determining the prevalence and predictors of parasitic contamination of fruits and vegetables collected from local markets in Jimma Town, Ethiopia, was conducted between April and May 2013. Methods. A total of 360 samples of fruits and vegetables were examined by sedimentation concentration after washing using normal saline. Results. The overall prevalence of parasitic contamination was 57.8%. Strongyloides like parasite (21.9%) was the most frequent parasitic contaminant followed by Toxocara Spp (14.7%), Cryptosporidium Spp (12.8%), H. nana (8.3%), G. lamblia (7.5%), A. lumbricoides (6.7%), E. histolytica/dispar (5.3%), Cyclospora spp (5.0%), and H. diminuta (1.4%). Washing of the fruits and vegetables before display for selling was significantly associated with decreased parasitic contamination (P < 0.001). Conclusion. Since fruits and vegetables are potential sources of transmission for intestinal parasites in the study area, consumers should always avoid acquiring parasitic infection from contaminated fruits and vegetables supplied in Jimma Town through proper cleaning and cooking.
背景。2013年4月至5月间，开展了一项旨在确定从埃塞俄比亚吉姆马镇当地市场采集的水果和蔬菜寄生虫污染患病率及预测因素的研究。方法。使用生理盐水清洗后，通过沉淀浓缩法对总共360份水果和蔬菜样本进行检测。结果。寄生虫污染的总体患病率为57.8%。类圆线虫样寄生虫（21.9%）是最常见的寄生虫污染物，其次是弓蛔虫属（14.7%）、隐孢子虫属（12.8%）、微小膜壳绦虫（8.3%）、蓝氏贾第鞭毛虫（7.5%）、蛔虫（6.7%）、溶组织内阿米巴/迪斯帕内阿米巴（5.3%）、环孢子虫属（5.0%）和缩小膜壳绦虫（1.4%）。在展示销售前对水果和蔬菜进行清洗与寄生虫污染减少显著相关（P < 0.001）。结论。由于在研究区域水果和蔬菜是肠道寄生虫的潜在传播源，消费者应始终通过适当清洗和烹饪，避免从吉姆马镇供应的受污染水果和蔬菜感染寄生虫。
