Giardia and Cryptosporidium are recognized as leading causes of waterborne and foodborne diarrhoeal disease with worldwide distribution. The study aimed to determine the protozoan contamination of various foods of plant origin. A total of 72 samples from 27 different varieties of fresh vegetables and fruits were collected from supermarkets and open markets in North-Western Greece and were examined using conventional diagnostic methods. Two out of 72 (2.8%) samples were found positive for Cryptosporidium oocysts, while no sample was found to be positive for Giardia cysts. The results show the presence of protozoan contamination in foods of plant origin, which may constitute a potential health hazard.

贾第鞭毛虫和隐孢子虫被认为是导致水传播和食源性腹泻病的主要原因，并在世界范围内分布。该研究旨在确定各种植物来源食品的原生动物污染。从希腊西北部的超市和露天市场收集了来自27种不同蔬菜和水果的72个样品，并使用常规诊断方法进行了检查。在72个样本中，有两个（2.8％）被发现对隐孢子虫卵囊呈阳性，而对贾第鞭毛虫囊肿则未被发现呈阳性。结果表明，植物来源食品中存在原生动物污染，这可能构成潜在的健康危害。
