Characterization of sludges - Detection and enumeration of Salmonella spp. in sludges, soils, soil improvers, growing media and biowastes - Part 3: Presence/absence method by liquid enrichment in peptone-novobiocin medium followed by Rapport-Vassiliadis
污泥的表征 - 沙门氏菌的检测和计数 在污泥 土壤 土壤改良剂 生长培养基和生物肥料中的应用 - 第3部分:蛋白胨 - 新生动物培养基中液体富集的存在/不存在方法 随后是Rapport-Vassiliadis
This part of the CEN Technical Report specifies a presence/absence procedure to detect Salmonella spp using a four-stage presence/absence method in up to 50g (wet weight) sample.
The method has a limit of detection of approximately 10 cfu/50 g wet weight sludge.
NOTE The objective is to cover untreated and treated sludges, soils, soil improvers, growing media and biowastes.
