Recontamination Effect of Treated Wastewater on Prevalence of Intestinal Helminthes: Case Study on Vegetable Producers Groups in Ouagadougou (Burkina Faso)

Urban Farm DB summary

This study in Ouagadougou, Burkina Faso, compared the parasitological characteristics of wastewater at a treatment plant's inlet and outlet, and in an open channel conveying treated wastewater to a garden site. Non-viable parasite cysts or eggs were found at the treatment plant, but viable parasite cysts and eggs were detected in the open channel. An epidemiological study demonstrated that open defecation by highly infected individuals within the garden site caused recontamination of the treated wastewater.
