(1) Background: and are important neglected parasites associated with diarrhea, such as the emerging . All three are foodborne parasites raising concerns in public health. This study intended to understand the intestinal parasite occurrence with emphasis on , , and in fresh fruits/vegetables sold in the main municipal markets of Maputo city, Mozambique. (2) Methods: A total of 321 fresh horticultural products were purchased in the rainy and dry seasons (five markets/two supermarkets/one agricultural zone). Light microscopy (LM) and PCR analysis were performed. (3) Results: By LM and/or PCR, 29.3% of the samples presented at least one parasite (rainy season: 22.9%; dry season: 35.1%). The most contaminated horticultural products: collected in dry season, from Zimpeto and Fajardo markets, lettuce and pointed white cabbage. Overall, 3.7% of , 1.3% of , and other intestinal parasites (pathogenic and non-pathogenic) were identified. (4) Conclusions: Important pathogenic intestinal parasites were identified in fruits/vegetables commercially purchased in Maputo City. This fact must be taken into consideration when planning the management of these horticultural markets, in order to reduce the risk of contamination of fresh produce by intestinal parasites, and to prevent foodborne diseases.
(1) 背景：隐孢子虫和贾第虫是与腹泻相关的重要被忽视寄生虫，如新兴的环孢子虫。这三种都是食源性寄生虫，引发了公共卫生方面的担忧。本研究旨在了解莫桑比克马普托市主要市政市场销售的新鲜水果/蔬菜中肠道寄生虫的发生情况，重点关注隐孢子虫、贾第虫和环孢子虫。(2) 方法：在雨季和旱季（五个市场/两个超市/一个农业区）共购买了321种新鲜园艺产品。进行了光学显微镜（LM）和聚合酶链反应（PCR）分析。(3) 结果：通过LM和/或PCR，29.3%的样本至少呈现一种寄生虫（雨季：22.9%；旱季：35.1%）。污染最严重的园艺产品：旱季从津佩托和法亚尔多市场采集的生菜和尖叶白菜。总体而言，鉴定出3.7%的隐孢子虫、1.3%的贾第虫以及其他肠道寄生虫（致病性和非致病性）。(4) 结论：在马普托市商业购买的水果/蔬菜中鉴定出重要的致病性肠道寄生虫。在规划这些园艺市场的管理时必须考虑到这一事实，以降低新鲜农产品被肠道寄生虫污染的风险，并预防食源性疾病。
