Parasitic contamination of vegetables is a public health problem in several countries and a challenge for food safety. With a short path from the field to the table, these foods can suffer several flaws in the good practices of production, transport and packaging which culminate in an offer of contaminated food to consumers. Therefore, this study describes a systematic review protocol with meta-analysis on evaluating the effectiveness of existing sanitation methods in removing parasites from vegetables.
The study will be conducted from published studies that report analyzes of parasites in vegetables before and after sanitization processes. The MEDLINE, Embase, Web of Science, FSTA, LILACS, Scopus and AGRIS electronic databases will be used. In addition, manual searches will be carried out through related articles, references to included articles and directories of theses and dissertations. The primary outcome will be the reduction or absence of parasitic forms in vegetables after the intervention or combined interventions, and the secondary outcomes will include: identification of the main parasites, assessment of the time required for processing and cost-effectiveness analysis. Two authors will independently screen the studies and extract data. Disagreements will be resolved by discussion, and a third reviewer will decide if there is no consensus. The criteria established by the Cochrane Manual (with some adaptations) will be used to assess the risk of bias in the studies and if the results are considered acceptable and sufficiently homogeneous, and a meta-analysis will be performed to synthesize the findings.
The systematic review produced from this protocol will provide evidence on the effectiveness of sanitation protocols for removing parasitic forms in vegetables and will contribute to strengthening food safety, with the adoption of best sanitation practices and prevention of health risks. In addition, the study may highlight possible knowledge gaps that need to be filled with new research.

蔬菜的寄生虫污染是一些国家的公共卫生问题，也是食品安全的一大挑战。由于这些食物从田间到餐桌的路径很短，因此在生产、运输和包装过程中，如果良好操作规范存在缺陷，最终会为消费者提供受污染的食物。因此，本研究描述了一项系统评价方案，通过 meta 分析评估现有的蔬菜清洁方法去除寄生虫的效果。
本研究将从报告蔬菜在清洁前后寄生虫分析的已发表研究中进行。将使用 MEDLINE、Embase、Web of Science、FSTA、LILACS、Scopus 和 AGRIS 电子数据库。此外，还将通过相关文章、纳入文章的参考文献以及论文和学位论文目录进行手动搜索。主要结局指标是干预或联合干预后蔬菜中寄生虫数量的减少或消失，次要结局指标将包括：主要寄生虫的鉴定、处理所需时间的评估和成本效益分析。两位作者将独立筛选研究并提取数据。如果存在分歧，将通过讨论解决，如果没有达成共识，则由第三位审稿人决定。将使用 Cochrane 手册（有一些调整）制定的标准评估研究的偏倚风险，如果结果被认为是可接受的且足够同质，则将进行 meta 分析以综合研究结果。
本方案产生的系统评价将为去除蔬菜中寄生虫形态的清洁方案的有效性提供证据，并通过采用最佳清洁实践和预防健康风险，为加强食品安全做出贡献。此外，该研究可能会突出需要新研究来填补的可能的知识空白。
