Microbiology of the food chain - Quantitative determination of emetic toxin (cereulide) using LC-MS/MS (ISO 18465:2017)
ISO 18465:2017 describes the quantitative analysis of the emetic toxin cereulide using high performance liquid chromatography (HPLC) or ultra performance liquid chromatography (UHPLC) connected to a tandem mass spectrometer (LC-MS/MS).
ISO 18465:2017 is applicable to the analysis of the toxin in products intended for human consumption.

Water quality - Guidance standard on determining the degree of modification of lake hydromorphology
This European Standard provides guidance on determining the degree of modification of lake hydromorphological features described in EN 16039. It enables consistent comparisons of hydromorphology between lakes within a country and between different countries in Europe, providing a method for broad based characterization across a wide spectrum of hydromorphological modification. Its primary aim is to assess ‘departure from naturalness’ for a given type of lake as a result of human pressures, and it suggests suitable sources of information that may contribute to characterizing the degree of modification of hydromorphological features. For wholly artificial lakes or reservoirs formed by damming rivers the aim is to assess the extent to which processes approximate to those in comparable natural water bodies. However, this standard does not replace methods that have been developed within particular countries for local assessment and reporting. Decisions on management for individual lakes require expert local knowledge and vary according to lake type.

Microbiology of the food chain -- Horizontal method for the detection, enumeration and serotyping of Salmonella -- Part 1: Detection of Salmonella spp.
ISO 6579-1:2017 specifies a horizontal method for the detection of Salmonella. It is applicable to the following:
- products intended for human consumption and the feeding of animals;
- environmental samples in the area of food production and food handling;
- samples from the primary production stage such as animal faeces, dust, and swabs.
With this horizontal method, most of the Salmonella serovars are intended to be detected. For the detection of some specific serovars, additional culture steps may be needed. For Salmonella Typhi and Salmonella Paratyphi, the procedure is described in Annex D.
The selective enrichment medium modified semi-solid Rappaport-Vassiliadis (MSRV) agar is intended for the detection of motile Salmonella and is not appropriate for the detection of non-motile Salmonella strains.
