This part of the CEN Technical Report method describes a method to detect and semi-quantitatively determine Salmonellae in sludges, soils, soil improvers, growing media and biowastes in accordance with the requirements of the European Sewage Sludge Regulation Revision of Directive 86/278/EEC (3rd Draft, CEN/TC 308 - doc525).The fully defined scope will be determined after the proposed validation trials have been agreed and carried out. The method has a limit of detection of approximately 1cfu/g wet weight sample.NOTEThe objective is to cover untreated and treated sludges, soils, soil improvers, growing media, biowastes and associated materials.
