Published on 17/01/2019

The working group 17 of  ISO/TC 34/SC 9 has conducted the revision of ISO 18593:2018 on Horizontal methods for surface sampling in the frame of microbiology of the food chain. This working group chaired by Léna Barre (EURL for Listeria monocytogenes) was composed by 24 members and 5 observers coming from all around the world. This CEN ISO standard published in June 2018 specifies horizontal methods for sampling techniques using contact plates, stick swabs, sponges and cloths on surfaces in the food chain environment in order to detect and enumerate culturable microorganisms such as pathogenic or non-pathogenic bacteria or yeasts and moulds.

Bertrand LOMBARD convened the 28th meeting of WG 2 Statistics of ISO/TC 34/SC 9 "Food products-Microbiology", held at Campden BRI, Campden UK, on 18-19 October. The main topic on the agenda was the revision of ISO/TS 19036, dealing with measurement uncertainty for quantitative determinations. This project is led by Basi JARVIS (Project Leader), Keith JEWEL and Paul IN'T VELD (co-Project Leaders). More precisely, WG 2 has given a follow-up to the ISO/CEN vote on ISO/DIS 19036.
