Sewage sludge is characterized by good fertilizer properties and contains significant amount of nutrients and organic matter subject to humification in soil. Therefore, sludge has been effectively spread in order to recultivate degraded areas or to replace humus material in green areas of towns, or to lay lawns by the owners of private houses. The sludge used for agricultural purposes has to meet certain chemical and biological criteria. This study examined the occurrence frequency of bacteria Salmonella in sewage sludge from eight wastewater treatment plants between 1999 and 2007. The results demonstrated that the occurrence frequency of bacteria Salmonella in the sewage sludge strongly depended on the technology used in the treatment plant.
