Helminth Eggs Parameter of Water Spinach Agriculture Field in Bandung

Urban Farm DB summary

Against a background of high helminth-infection prevalence in Indonesia — which led the government to issue a 2017 ministerial regulation on preventing soil-transmitted helminths (STH) — this study investigated the potential presence of helminth eggs capable of causing STH infection in two urban agricultural areas in the northern and southern parts of Bandung City. Samples of inlet and plantation-area water, soil, and harvested water spinach from both areas were analyzed for helminth eggs using a modified Bailinger method, and egg counts of 1–119 eggs/L were found across the water, soil, and vegetable samples. The results confirmed that irrigation water in both areas was contaminated with feces, with average fecal coliform counts exceeding the allowable value for irrigation water under Indonesia's Grade 4 water-quality criteria; variation in egg counts was attributed to environmental conditions such as temperature, humidity, and soil type. Helminth-egg levels in the irrigation water and land samples exceeded the values recommended by the WHO's 2006 guidelines for safe use of wastewater in agriculture, which the study links to an increased risk of helminth infection among consumers, agricultural workers, and residents near the farmland.
