Bertrand LOMBARD organised on 13 December the 2nd web-meeting of a working group preparing a guidance document on the organisation of proficiency tests (PTs) by NRLs for the national networks of official laboratories they coordinate. This EURLs working group is composed of representatives from EURLs Salmonella, Campylobacter, VTEC, Listeria monocytogenes and Coagulase Positive Staphylococci, The draft is based on a EURL Listeria monocytogenes document dealing with partial outsourcing of PTs organised by NRLs. The scope of the document being drafted is now wider. This document should be finalised in 2019 and will be circulated to the respective NRL networks for consultation.

This Joint scientific Conference on Foodborne pathogens and whole Genome Sequencing is organised in Paris from Tuesday 26 to Thursday 28 March by Anses (France) / BfR (Germany) / DTU Food (Denmark) / NIFDS (South Korea).   Fuelled by the reduction in the cost of sequencing and the exceptionally rapid development of algorithmic and calculation resources, the medical, agronomic and food sectors have been shaken by the genomic revolution. At the initiative of four national institutions for food safety and risk assessment in France, Denmark, Germany, and South Korea, this conference will bring together researchers, risk assessors and risk managers for an update on the impact on food safety that whole genome sequencing (WGS) approaches already have, and will continue to have in the near future. The scientific presentations will cover recent developments in the data-based WGS methods used in outbreak detection, investigation and epidemiological surveillance. The bioinformatics methods and platforms used to characterise foodborne pathogens and interpret phenotypic variations (e.g. virulence, antimicrobial resistance and persistence) will be presented, while refinement of quantitative microbial risk assessment (QMRA) models with the implementation of new comprehensive genomic data will be discussed. In addition, the potential of metagenomics in the food safety field, with a special focus on virology, will also be addressed. A round table will close the meeting with representatives of major international public health institutions to discuss initiatives for the promotion of genomic approaches. Participation in the meeting is free of charge but requires prior registration. Link provided hereafter: website, programme and registration.

[relayed from CDC Health Alert Network] The New York State Department of Health and Pennsylvania Department of Health are investigating Brucella RB51 exposures that may be connected to consuming raw (unpasteurized) milk from Miller’s Biodiversity Farm in Quarryville, Pennsylvania. Symptoms of brucellosis can include fever, sweats, malaise, anorexia, headache, fatigue, muscle and joint pain, and potentially more serious complications (e.g., endocarditis, hepatomegaly, splenomegaly, and neurologic symptoms). In pregnant patients, Brucella infections can be associated with miscarriage. Symptom onset can occur anywhere from five days to six months following exposure. As of January 22, 2019, exposures have been identified in 19 states: Alabama, California, Connecticut, Florida, Georgia, Iowa, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, and Virginia.

Yacine NIA and Isabelle MUTEL organised a training session held in our permises in Maisons-Alfort (FR) on 11-12 December 2018. This training session was dedicated to the detection of Staphylococcal Enterotoxins according to the European Screening method and the new EN ISO 19020. NRLs Participants : Ivana IVANOVIC - Agroscope of Switzerland; Thorsten BLUME - SpiezLab of Switzerland; Marina DOUKA - Department of Food Hygiene of Athens of Greece.

Bertrand LOMBARD participated virtually (teleconference) to a part of the last meeting of the Working Group 3 on method validation of the subcommitte ISO/TC 34/SC 9 “Food products-Microbiology”. It took place on 4-6 December 2018 at Sciensano (BE-NRL for Listeria monocytogenes & coagulase positive staphylococci, Brussels). WG 3 is in charge of developing the series EN ISO 16140 on method validation/verification in food chain microbiology. This meeting was mainly dedicated to the preparation of the final vote, further to the ISO/DIS vote and CEN Enquiry, on the 4 following parts: Part 3: method verification; Part 4: method validation in a single laboratory; Part 5: factorial interlaboratory validation for non-proprietary methods; Part 6: validation of alternative (proprietary) methods for microbiological confirmation and typing procedures. The final votes are expected to be launched by mid-2019. B. Lombard ensured a liaison with WG 2 which provides a statistical expertise to prepare these standards.

On 19 and 20 September 2018, Yacine NIA organised at the NRL a training session at AGES, the Autrian NRL for CPS in Graz. This training session was dedicated to the detection of Staphylococcal Enterotoxins according to the European Screening method. Sigrid Fleck, Kornelia Voetsch, Kathrin Hauser, Andrea Kormann-Klement took part to the practical session.

Yacine NIA from EURL CPS and Kati MIELKE from BfR (DE NRL) organised on 6th September a technical meeting on the confirmatory ELISA for Staphylococcal Enterotoxins in food matrices.

The working group 17 of  ISO/TC 34/SC 9 has conducted the revision of EN 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: Microbiology of the food chain - Horizontal methods for surface sampling (ISO 18593:2018).
