Popis: Background and Aim: Water crisis in many regions of the world especially arid and semi-arid areas such as Iran, is an important obstacle for socioeconomic development and food security. Under such circumstances, wastewater reuse in agriculture can be regarded an important alternative water source. However, treated wastewater may contain some types of pathogenic microorganisms which can threaten human health. In the present study we compared the impacts of treated wastewater (TWW) and tap water irrigation on microbiological quality of soil and crops (maize and maize leaves) through a furrow irrigation system in an experimental field. Materials and Methods: Total and fecal coliforms and Escherichia coli were monitored as indicator bacteria in TWW, irrigated soil and harvested maize and maize leaves. We investigated the presence of Salmonella and Shigella by using a combination of culture and molecular methods. Statistical analyses were performed by SPSS 22.0 software. P
