Abstract

Background: Parasitic contamination in vegetables is a reality in several countries and a challenge for food safety. The risk of consumption usually raw, associated with failures in good practices of production, transportation, and preparation further increase the possibility of ingesting contaminated food. Given this, a systematic review was carried out to scientifically demonstrate the effectiveness of sanitization protocols in the parasitic decontamination of plants.

Methods: This review was conducted following the guidelines of the Cochrane Manual, being registered in the PROSPERO protocol base (CRD42020206929) and reported according to the PRISMA 2020 statement. The review evaluated studies published in the MEDLINE, Embase, Web of Science, FSTA, LILACS, and AGRIS databases, as well as manual searches of related articles, references, and theses and dissertations directories. The meta-analysis was performed using the Revman 5 software program, the bias assessment used the Robins I Tools with some adaptations, and the quality of the evidence was evaluated using GRADE.

Discussion: The review included a total of 31 studies, most of which were carried out in countries with a high incidence of plant parasites, such as Brazil and Iran. Interventions combined with 200ppm chlorination preceded by brushing, rinsing, or immersion in detergent showed the greatest efficiency in parasitic decontamination. Despite the high heterogeneity and risk of bias in the primary studies, this review can inspire the planning of new studies which observe the critical and methodological evaluation for research in the field of food safety.
