Abstract:
Food-borne parasites are major sources of human and animal illness, posing severe health risks in places with poor water quality, cleanliness, and sanitation. Their definitive hosts excrete eggs/ larvae in their feces, which pollute the soil and can there after be ingested via consumption of eaten raw vegetables. Objective: To investigate the type and degree of contamination caused by parasites in regularly used raw vegetables, green fodder and soil samples collected from open fields in Egypt's east delta. Methods: Soil, vegetables and green fodder samples were gathered throughout a year period to represent all seasons. Parasitological concentrations and staining techniques were used to recover the parasitic life forms. Results: More than 60% of soil, eatenraw green vegetables and green fodder samples confirmed positive for parasitic contamination. The majority of green vegetables and soil samples harbor at least one parasite species. Ascaris species eggs, Trichuris species eggs, and Giardia species cysts were mostly isolated from vegetables under investigation especially those with uneven surfaces. The proportion of parasite infection in vegetables samples was highest in spring followed by summer and autumn. The prevalence rate was the lowest in the winter. Conclusion: A significant load of parasitic infection in raw vegetables and green fodder cultivated in open fields as well as in the soil from which these vegetables were grown were demonstrated. These results confirm the urgent need to deploy strict control measures during the pre-harvest period of eaten-raw vegetables and soil, a critical step in reducing foodborne transmission of these parasites. Key words: Food-borne parasites, Soil, Vegetables, Green fodder, Ascaris species
