Abstract
The aim of this survey is to assess the microbiological impact of irrigation water on lettuces produced on two urban agricultural sites and then sold in markets. Lettuces irrigated with shallow groundwater were more contaminated (8% at both Pikine and Patte d’Oie sites) compared to those irrigated with wastewater (4% at Pikine) or well water (5% at Patte d’Oie). Results confirm that the reuse of wastewater in irrigation is an alternative to animal manure. Its risk of microbial contamination can be significantly reduced by washing the vegetables with tap water before they are sold.
