“…Vegetables are an essential component of a healthy diet, and many of them are consumed raw. Thus, they may play a crucial role in the transmission of parasitic pathogens spread by food (Geary & Haque, 2021;Kpoda et al, 2022;Nazemi et al, 2012). Examining vegetables sold in markets and stores for parasite contamination could highlight improper vegetable harvesting and handling practices and highlight the prevalence of intestinal illnesses among local entities (Alhabbal, 2015).…”

“…Also, sewage water has been used for irrigation in many developing countries along with human and animal excreta as fertilizers (Orlandi et al, 2002). This increased the spread of parasites in many non-endemic regions in different countries (Geary & Haque, 2021). In addition, they import fruits and vegetables from various countries with unknown hygiene practices in their processing (Gemechu et al, 2023).…”

Vegetables are a crucial component of every diet and a good source of vitamins and minerals. Many raw vegetables, such as salads, are consumed, and consuming raw vegetables contaminated with human and animal feces can lead to a variety of intestinal parasite diseases. The goal of this cross-sectional study was to investigate the incidence of contamination of green leafy vegetables with human intestinal parasites, as well as identify the most common parasite species and any seasonal variation in parasite abundance in green leafy vegetables found and sold for human consumption in various markets and stores in Jeddah. To the best of our knowledge, no research has been conducted on the prevalence of parasite-contaminated vegetables in Jeddah. From September 2020 to July 2021, 250 leafy vegetables (coriander, watercress, lettuce, parsley, leek, and green onion) were collected from various markets and stores in Jeddah. The vegetables were sorted, labelled, and evaluated in the laboratory after being completely washed with distilled water, examined for sediment, staining, and microscopically examined. Chromatographic immunoassay tests were also used to confirm parasite identification. Intestinal parasites were discovered in 35.2% of the vegetables (88/250). Coriander was the most contaminated (64.2%), while green onion was the least contaminated (21.9%). Blastocystis spp. was the most often discovered parasite (55.7%), followed by Strongyloides spp. larva (22.7%) and Entamoeba coli cysts (6.8%). Summer has the greatest percentage of parasites, followed by autumn, while winter has the fewest. There was no statistically significant relationship between the kind of vegetable, seasonal parasite prevalence in green vegetables, and parasite type.These findings highlight the importance of inspecting vegetables grown or imported from endemic countries for parasite contamination. In Jeddah, several fresh green vegetables were tainted with intestinal parasites. This demonstrates that those who consume raw vegetables regularly may be susceptible to parasitic illnesses. These findings highlight the need of monitoring vegetables grown or imported from parasitic-endemic areas. As a result, it is critical to establish strategies and control measures to limit the likelihood of parasites in food-borne diseases.

“…Causing primarily subtle morbidity, STH infections rarely result in death. However, chronic infections may lead to digestive disorders and micronutrient deficiencies, including iron deficiency anemia, and thus, particularly have an impact on children’s physical growth and mental development, as well as on pregnancy outcomes [ 5 , 7 , 8 ].…”

Optimizing Implementation of Preventive Chemotherapy against Soil-Transmitted Helminthiasis and Intestinal Schistosomiasis Using High-Resolution Data: Field-Based Experiences from Côte d’Ivoire

et al. 2022

Background: Despite efforts to control neglected tropical diseases (NTDs) using preventive chemotherapy (PC), soil-transmitted helminthiases and schistosomiasis remain widely prevalent in sub-Saharan Africa. The current PC regimen in endemic settings is defined based on health district-level prevalence. This work aims to highlight the need for high-resolution data when elimination, rather than morbidity control, is the targeted goal. Methodology: Cross-sectional parasitological surveys were conducted from July to August 2019 and from September to October 2019, respectively, across the entire Dabou and Jacqueville health districts in southern Côte d’Ivoire. From every village, 60 school-aged children (6–15 years) were randomly selected and invited to provide one fresh stool sample, whereof duplicate Kato–Katz thick smears were prepared and read by two independent technicians. Principal Findings: 4338 school-aged children from 77 villages were screened from the Dabou (n = 2174; 50.12%, 39 villages) and Jacqueville (n = 2164; 49.88%, 38 villages) health districts. The prevalence of any soil-transmitted helminth (STH) infection was 12.47% and 11.09% in the Dabou and Jacqueville health districts, respectively. Species-specific district-level prevalence remained below 10%, varying between 0.51% (hookworm in Jacqueville) and 9.06% (Trichuris trichiura in Dabou). However, when considering sub-districts or villages only, several STH infection hotspots (five sub-districts with ≥20% and four villages with more than 50% infected) were observed. Schistosoma mansoni infection was found in less than 1% of the examined children in each health district. Conclusions/Significance: We conclude that keeping health district-level prevalence as a reference for PC implementation leaves many high-risk sub-districts or villages requiring PC (≥20% prevalence) untreated. To avoid maintaining those high-risk villages as STH reservoirs by skipping control interventions and jeopardizing the successes already achieved in STH control through PC during the past two decades, precision mapping is required. Further investigation is needed to assess cost-efficient approaches to implement small-scale disease surveillance.
