The IAFP European Symposium is an international conference on food safety organized by the International Association for Food Protection (IAFP). The conference brought together more than 400 participants from around the world (17 countries represented) from 24th to 26th April 2019 at the Cité des Congrès in Nantes.
This congress was supported by SECALIM, of which two members: Jeanne-Marie Membré and Nabila Haddad, participated in the organizing committee of the conference and the local committee.
The congress included 15 symposia, 9 technical sessions and 3 round tables covering many areas of food safety: hygiene control including consumer practices, standards in food microbiology, detection and control of pathogens including Campylobacter, recent methods of identifying emerging risks, food spoilage, risk assessment and risk / benefit assessment, etc.

UMR SECALIM participated actively in this conference. No less than twenty of its members were present at the scientific days.

A total of four symposia were organized by SECALIM:
• Network analysis to better describe the functions and dynamics of microbial food ecosystems¹
• New approaches to modeling the microbiological alteration of foods²
• The challenges of accurately detecting and quantifying Campylobacter³
• Ongoing research activities on the risk-benefit assessment of food⁴

The symposia principle is to illustrate the scientific advances around a common theme, with the interventions of three scientists from different laboratories / companies and countries. As part of these symposia, three of our doctoral students, Juliana de Oliveira Mota⁵, Ngoc-Du Luong⁶ and Benjamin Duqué⁷ were able to communicate their research results.

Ngoc-Du Luong, presented an innovative method of spoilage modeling by a Bayeasian approach6	Juliana de Oliveira Mota, presented risk-benefit assessment of read meat5

Benjamin Duqué, explains how better predict the behaviour of Campylobacter jejuni by the use of gene expression biomarkers7

Five oral communications were also presented in the technical sessions.

Vincent Tesson8, in post-doctoral position in SECALIM, presented a critical analysis of microbiological risk assessment models for meat.

Emmanuel Jaffrès9, lecturer at SECALIM, presented the PhD work of Nassima Illikoud, on the mechanisms of microbial spoilage due to   Brochothrix thermosphacta in seafood and meat products.

Nicolas Helsens10, PhD student at SECALIM, exposed his studies on the bacterial resistome in rainbow trout fillets.

Aurélien Maillet11, PhD student at SECALIM, funded by Biofortis, described the analysis of contamination of the factory environmental  contamination in smoked salmon industrial plant.

At last, another oral communication proposed by Géraldine Boué, lecturer at SECALIM enabled to present the advances in risk-benefit assessment in food in the framework of the European project RiskBenefit4EU¹².
Fours posters were also displayed^13-16 .

Agnès Bouju-Albert15, technician at SECALIM, presented a method of quantification of viable cells of  Brochothrix thermosphacta

Morgane Nennig16, phD student at SECALIM, in co-supervision with the Luxembourg National Laboratory for Health, presents her poster on the stability of genotypes of Campylobacter jejuni from human and food isolates by Whole Genome Sequencing (WGS)

This unmissable conference was an opportunity for young scientists to present their work and for seniors to consolidate their existing collaborations or to open new ones.
