Abstract：
UNASSIGNED: Raw vegetables have been considered vehicles of enteroparasites. South American countries are among the most important exporters of fresh vegetables, including Ecuador, which has a tropical climate and soils rich in organic matter that allow it to harvest throughout the year for sale to different countries. The aim of the study was to assess the occurrence of the parasitic contamination of fruits, vegetables and leafy greens grown in an agricultural area of the Ecuadorian Andes.
UNASSIGNED: A cross-sectional field study was conducted with snowball sampling on 1,416 samples (516 fruits, 488 vegetables, and 412 leafy greens). Each sample were washed with water, and the resulting solution after removing the vegetables, was subjected to 24-hour sedimentation. The concentrated sediment underwent microscopic analysis.
UNASSIGNED: The overall positivity for parasitic contamination was 63.4%, with leafy greens having the highest contamination rate (76.9%) (P<0.0001), surpassing vegetables (67.8%) and fruits (48.4%). Cabbage (100%), onions (84%), and strawberries (60.2%) emerged as the most contaminated within their respective groups. Protozoa were more prevalent (49.6%) than helminths (15.5%) (P<0.0001). Blastocystis sp. (33.5%) ranked highest, followed by Eimeria spp. (26.3%), Entamoeba spp. (10.3%), Giardia spp. (8.3%), Balantidium spp. (6.9%), Cryptosporidium spp. (6.6%), Cyclospora spp. (4.4%), Cystoisospora spp. (0.5%), Strongylida (15.5%), and Ascaris spp. (0.4%).
UNASSIGNED: The study reveals that vegetables and fruits for human consumption from this area of the Ecuadorian Andes are highly contaminated with various parasites, constituting a possible source of infection for humans and animals in this area, or in non-endemic areas where these products are marketed. The finding emphasizes the need for strict hygienic measures in agricultural crops, which will be properly achieved through the treatment of soil, manure and water used for cultivation.

摘要：
背景：生蔬菜被认为是肠寄生虫的载体。南美国家是新鲜蔬菜最重要的出口国之一；厄瓜多尔的热带气候和富含有机物的土壤使其能够全年收获并出售给不同的国家。这项研究的目的是评估水果寄生虫污染的发生，在厄瓜多尔安第斯山脉的农业区种植的蔬菜和绿叶蔬菜。方法：实地研究，横截面,对1,416个样本(516个水果,488种蔬菜，和412绿叶蔬菜)。每个样品用水洗涤，以及去除蔬菜后产生的溶液，进行24小时沉降。对浓缩的沉积物进行显微镜分析。结果:63.4%的样本检出寄生虫,绿叶蔬菜污染最严重(76.9%)(P<0.0001)，（蔬菜占67.8%，水果占48.4%），其中，卷心菜（100%），洋葱(84%)和草莓(60.2%)受污染最严重。原生动物(49.6%)高于蠕虫(15.5%)(P<0.0001)。囊胚。(33.5%)最高，其次是艾美球虫。（26.3%），Entamoebaspp.（10.3%），贾第虫。（8.3%），Balantidiumspp.（6.9%）；隐孢子虫属。（6.6%），环孢菌属。（4.4%），囊孢子菌属。（0.5％）；Strongylida（15.5％）和A虫。(0.4%)。结论：水果的消费，蔬菜,这些作物中的绿叶蔬菜可能是该地区或销售这些产品的非流行地区的人类和动物的感染源。这项研究确定了在生长中需要严格的卫生措施；这将通过土壤处理来适当实现，用于种植的肥料和水。
