“…Trabajos reportados por Garzón-Zúñiga et al (2016) y Montero-Aguirre et al (2016) reportan datos similares de 139.4 mg L -1 y 112 mg L -1 respectivamente. En la investigación realizada por Campos et al (2018) evaluaron agua residual para riego agrícola y concluyeron que un alto contenido de SST tiene una fuerte correlación con la presencia de huevos de helminto (HH), generando problemas de salud al reutilizar el agua.…”

El uso de agua residual tratada de origen urbano para irrigar suelos agrícolas destinados a la producción de forrajes es una alternativa que favorece el aporte de nutrientes al cultivo y minimiza la contaminación en los sitios de descarga; sin embargo, se requiere conocimiento acerca de la calidad de esta agua. El objetivo del estudio fue determinar la calidad del efluente de cuatro plantas tratadoras de agua residual (PTAR) de la Comarca Lagunera. Los análisis de calidad se llevaron a cabo con las metodologías de diversas normas nacionales. Los muestreos a las plantas tratadoras se realizaron durante once meses (abril 2014 a febrero 2015). Los resultados muestran poca variación mensual a excepción de la planta LA1. Los afluentes de PTAR LO1 y LO2 tienen de 22 a 25 mg L-1 de N, mientras PTAR LA1 tiene mayor concentración de P 4 mg L-1 y K 22 mg L-1, en cuanto la calidad agronómica es cuestionable por la alta salinidad y sodicidad. En cuanto a los parámetros microbiológicos todas las PTAR exceden los límites máximos permisibles (LMP) de la NOM- 003- ECOL- 1997 en cuanto al contenido de huevos de helminto, excediendo también los LMP metales pesados, de la NOM-001-SEMARNAT-1996 en Pb y Cd.

“…Regarding the concentration of eggs, previous studies have reported total values of 0.1 to 3 helminth eggs per liter of untreated water, and 0.1 to 1 viable helminth egg per liter of treated water in the Savannah of Bogotá (Campos-Pinilla et al 2008 ; Campos et al 2018 ). Our results reported average numbers ranging from 0 to 5.54 eggs/L and an average of 1.9 nematode larvae per L. These results suggest that these samples are not in compliance with WHO quality criteria guidelines (Campos et al 2018 ).…”

The World Health Organization (WHO) has established as a criterion of parasitological quality for irrigation water, ≤ 1 helminth egg/liter, which guarantees the safety in agricultural products. In this study, the presence of parasites in surface water used for irrigation of crops (n = 96) and vegetables (celery and lettuce) (n = 120), from the Former La Ramada irrigation district, was evaluated using conventional and molecular parasitological methods. Our findings showed contamination of irrigation systems in the study area with domestic wastewater, demonstrated by the presence of Ancylostomatidae eggs, Ascaris spp., Hymenolepis spp., Trichuris spp., Capillaria spp., Giardia spp. cysts, and oocysts of Toxoplasma gondii and Cryptosporidium spp. A prevalence of 33% and 23.3% was calculated for helminths and protozoa, respectively in vegetables, representing a possible risk to human and animal health in relation to these parasites. These findings show the need for continuous monitoring of the water quality used for crop irrigation, as well as the safety of food, taking into account the values established in national and international regulations.

“…And some species of protozoan parasites could cause serious health problems and economic issues (Yusof, 2017). Campos et al (2018) have found helminth eggs in agricultural irrigation water (0.1-3 total helminth eggs/L) in Colombia. In addition, Kafle et al (2014) obtained eggs of Ascaris lumbricoides, Strongyloides stercoralis and Giardia in vegetables soil in Nepal.…”

Fresh vegetables are an important part of a healthy diet. Consumed raw, they could be agents of transmission of intestinal parasites. The frequency and variability of parasites eggs on thirty-two samples each of lettuce, tomato and cucumber form irrigated vegetable farms in Bamako, Kati, Baguineda, Samanko, Sikasso and Niono were evaluated. The parasite load was assessed using Uga et al. method, which consist the counting of parasite eggs and cysts in 100 g of vegetable. The overall prevalence of parasitic contamination of vegetables was 20.83% of which 41.66% for lettuce and 16.66% for tomato. Cucumber was free of parasites eggs. Parasites found on the vegetables were Entamoeba coli and Trichomonas intestinalis (24.19% each), Ascaris lumbricoides (13.25%), Giardia intestinalis (12.9%), Balantidium coli (11.29%), Entamoeba histolitica (7.26%), Fasciola hepatica (3.23%), Trichinella spiralis (1.61%), Ancylostoma duodenale and Schistosoma intercalatum (1.04% each). The frequency of parasites on lettuce was 83.33% each in Bamako and Niono; 50% in Kati; 16.66% each in Baguineda and Samanko and 0% in Sikasso. Consumption of vegetables contaminated by parasites can cause a health risk for consumers.
