This document specifies a method for the detection of Salmonella spp. in organic fertilizers, organo-mineral fertilizers, inorganic fertilizers which contain more than 1 % by mass of organic carbon, other than organic carbon from chelating or complexing agents, nitrification inhibitors, denitrification inhibitors or urease inhibitors, coating agents, urea or calcium cyanamide. The method is tested for solid and liquid products.
This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Inhibitors, Plant Biostimulants, and where the following category: organic fertilizers, organo- mineral fertilizers, inorganic fertilizer is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer, the organo-mineral fertilizer or the inorganic fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply.
Most of the Salmonella serovars are detected with the method described in this document. For the detection of some specific Salmonella serovars (e.g., Salmonella Typhi and Salmonella Paratyphi), additional cultivation steps might be necessary.
NOTE: This method has been validated in an interlaboratory study with specific products that were present on the market during the study.
Regulation (EU) 2019/1009 on fertilizing products includes requirements for organic and organo- mineral fertilizers. Appropriate methods are necessary to verify the conformity of CE-marked fertilizing products to the requirements of the Regulation.
The European Standard on “Organic, organo-mineral and inorganic fertilizers - Detection of Salmonella spp” describes the test methods to be applied for verifying the conformity of organic, organo-mineral and inorganic fertilizers with the requirements set out in Regulation (EU) 2019/1009.
This method is intended to be referred to in the harmonized standard “Organic, Organo-mineral and inorganic fertilizers – Detection of specific pathogens” in the framework of standardization request M/564
