Urban Farm DB summary
This study in Dakar, Senegal, assessed Salmonella contamination in irrigation water and lettuce across three urban agricultural sites. Sites using wastewater (Pikine and Patte d’Oie) showed high Salmonella prevalence in water (70-90%) and vegetables (20-80%), while a tap water site (Lendeng) had no contamination. Market-sourced lettuce also tested positive (28.57%), indicating public health risks from untreated wastewater use.
