In order to ensure the reliability of the analyses carried out by our network of laboratories, our reference laboratory for Brucellosis is currently undertaking an inter-laboratory proficiency testing to assess the effectiveness of bovine milk serological methods. All details and provisional agenda can be found on our ANSES platform (LEILA) --> https://leila.anses.fr/ Deadline for registration = 1rst March, 2024 If you need more information, please contact us at eurl.brucellosis@anses.fr !   #brucellosis #ILPT #cattle #serology #milk 

Congratulations to Thierno Diallo, who became a Doctor of Analytical Chemistry on February 8. Thierno brilliantly defended his thesis, which focused both on consumer exposure to mixtures of contaminants present in bivalves (mussels and oysters) and on the potential consequences of these molecules on the health of these marine organisms. For a number of years, unexplained deaths of bivalves have been observed along the French Atlantic coast, particularly around La Rochelle. The hypothesis underlying this thesis work was that the punctual and/or continuous exposure of bivalves to a mixture of contaminants could weaken these organisms, thereby facilitating the deadly work of viruses and bacteria. To address this issue, longitudinal monitoring of various sites impacted or not by these mortalities was carried out for a year, and targeted and non-targeted approaches were implemented on the samples taken. These analyses enabled us to characterize in situ the cocktails of contaminants to which these marine organisms were actually exposed, and to shed light on a number of hypotheses concerning the dynamics and origins of these contaminants in the natural environment. In addition, this thesis has helped to highlight the potential of high-resolution mass spectrometry to better understand the impact of anthropization on marine organisms and on our dietary exposure. This thesis was an integral part of the ANR JCJC AlimOmic project. At the end of this thesis, which was carried out between the University of La Rochelle and Anses (Laboratoire de Sécurité des Aliments de Maisons-Alfort), no less than 8 articles were published in A/A+ ranking journals, and numerous national and international congresses were attended. These achievements are quite exceptional, and were unanimously praised by the members of Thierno's thesis jury. The supervisory team would like to thank Bruno Le Bizec (Oniris Laberca), Farida Akcha (Ifremer), Elena Gomez (Univ. Montpellier) and Stéphane Bayen (Univ. McGill) for their careful evaluation of this work.

On December 6, Yoann Devriendt-Renault defended his doctoral thesis at the Ecole Nationale Vétérinaire d'Alfort (ENVA) - specializing in Chemistry - in Maisons-Alfort. The thesis, entitled "Du sol à l'assiette - impact des traitements thermiques sur le devenir de la chlordécone (CLD) dans les aliments et les sols antillais", is an integral part of the ANR JCJC AlimOmic project (www.alimomic.fr). The thesis was supervised by Julien Parinet (LSAl-PBM) and Thierry Guérin (DSP). The aim of this thesis was to answer the question of how to reduce an individual's exposure to CLD when ingesting an impregnated animal foodstuff. Through his work, Yoann was first able to calculate the processing factors (PF) of various matrices (fish, lobster, chicken, pork, etc.) subjected to different cooking methods (oven, frying pan and microwave). These PF may be useful for risk assessment. Microwaves were also found to be the most effective way of reducing CLD levels. In a second stage, elimination routes were investigated and revealed the possibility of volatilization of CLD, which is also transferred to cooking juices. inally, it would appear that CLD is partly converted to Chlordecol by heat treatment. This original work opens up a number of new avenues of inquiry, and questions which the LSAL will be pursuing in the coming months and years, in order to support risk assessment. The thesis jury, comprising Dr. Magalie Jannoyer (CIRAD) and Pr. Jean Luc Boudenne (Univ ; Aix-Marseille) as rapporteurs, Pr. Patrick Hohener (Univ. Aix-Marseille) and Dr. Agnès Fournier (Univ. Lorraine) as examiners, recognized the high quality of the oral presentation, the manuscript and the scientific valorization associated with this thesis, with 2 publications in 1st quartile (Q1) journals! Congratulations to Yoann on his ENVA doctorate!

The Centre is celebrating the publication of its fifth scientific paper as a result of the work carried out in Activity 3 in 2022.  The present study demonstrates that mixtures of carbon dioxide with nitrogen improve a broiler chicken’s welfare during stunning since they result in a more rapid induction of unconsciousness and reduce the aversion experienced, compared to carbon dioxide in two phases, in broiler chickens. This article named " Alternatives to Carbon Dioxide in Two Phases for the Improvement of Broiler Chickens’ Welfare during Stunning" has been published as part of the Special Issue Animal Stress and Welfare during Transport and Slaughtering, and is available here.

Agenda Program 2024 is now available since January 2024.

Please have a look at this webinar scheduled for December 20th, 2023, 9:00-12:00 CEST

We look forward to welcoming a new member to the EURCAW family! On 17 January the fourth European Union Reference Centre for Animal Welfare was designated – this new EURCAW will focus on aquatic species.   EURCAW Aquatic Animals will be led by the University of Crete in Greece, in partnership with the Biology Centre of the Czech Academy of Sciences, Institute of Parasitology in Czechia and the Universitat Autònoma de Barcelona in Spain.   The designation was published on 19 January in the ‘COMMISSION IMPLEMENTING DECISION 2024/266 of 17 January 2024 designating a European Union reference centre for the welfare of aquatic animals in accordance with Regulation (EU) 2017/625 of the European Parliament and of the Council’.   The new EURCAW will officially start work on 1 February 2024 and the designation will be reviewed every 7 years from the date of application of the Decision.   The implementing decision is available at: https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=OJ:L_202400266&qid=1705652151941 The press release from the European Commission, issued on 15 January 2024: https://ec.europa.eu/newsroom/sante/items/814529/en
