We are excited to announce a PhD opportunity within the SafeFood4ClimDiet project "Characterization and ranking of microbiological risks associated with new food practices induced by climate change" This PhD will provide the opportunity to work at the intersection of public health, climate change, and food safety. About the PhD Project This doctoral research will be part of a collaborative effort between ANSES (French Agency for Food, Environmental and Occupational Health & Safety) and INRAE (National Research Institute for Agriculture, Food, and Environment). The project focuses on understanding how climate change influences food production, distribution, and consumption patterns, and the resulting microbiological risks to public health. Research Objectives: Several research questions will be explored: What are the microbiological hazards associated with new consumption practices in mainland France, Corsica, and overseas territories, and which foods are affected? What tools and methodologies can be used to robustly and predictively assess these risks to rank them based on their likelihood of occurrence and severity? What are the microbiological risks projected for 2050, and how can we adapt to them This research will be interdisciplinary, combining risk assessment, microbiology, food science, and data science, all crucial to tackling the current environmental challenges. Key Details of the PhD Position: PhD supervision by Jeanne-Marie Membré (INRAE) and co-supervision by Estelle Chaix (Anses) Location: The PhD will be based at Anses in Maisons-Alfort (94), with occasional travel to INRAE – UMR Secalim in Nantes (44). Affiliated Doctoral School: ED VAAME (Vegetal Animal Food Sea Environment). Start Date: September 2025. Application Deadline: June 20, 2025. Who Are We Looking For? We are seeking a highly motivated candidate with a strong interest in public health, climate change, and food safety. The ideal candidate will have a Master’s degree (or equivalent) in risk assessment, food science, or agri-food engineering. The candidate should also have experience or a strong interest in data analysis, programming (R), and risk modelling. Key skills and interests include: Understanding the relationship between climate change and food safety. Experience with scientific data management and analysis. Strong organizational, planning, and communication skills. Ability to work in an interdisciplinary team environment. To apply and for more details, please refer to the full announcement.

The 15th annual workshop will be held at ANSES Sophia Antipolis (France) on Wednesday 15th October 2025. The EURL will welcome the representatives of the European and Third-Country NRLs. The annual workshop is the opportunity for the NRL network to exchange, to receive news from the partners and to give information on the activities run during the year. More information to come. Stay tuned!

An outbreak of Foot-and-Mouth Disease has been reported in Slovakia in domestic cattle for the first time in 50 years. Cases have been detected in three farms located in the southern part of the country. This is the third case in the EU in 2025 after the outbreaks in Germany in January and in Hungary in March. Restriction zones have been set up around the farms. The identification of the serotype is pending. For more information: Slovakia records first foot-and-mouth cases, minister says | Reuters; WAHIS

This scientific note presents a state of play of the geographical distribution and spread of Tropilaelaps spp. mites, parasite of bees and exotic in the European Union (EU) in March 2025. It can be downloaded as a pdf here.   It has been initially published in French on the website of the French Animal Health Epidemiological Surveillance Platform on 3rd March 2025. It was translated into English and updated following the detection of Tropilaelaps spp. in Azerbaijan.   Highlights  Geographical spread of Tropilaelaps spp. mites occured in the last decade. Detection of Tropilaelaps mercedesae in territories close to the European Union: presence in the Russian regions of Krasnodar and Rostov (close to Ukraine and Georgia) since 2021 at least, and in Georgia since 2023 at least. Increased risk of introduction into the EU due to the geographical spread of the parasite and climatic conditions favouring its survival. Among the two species of Tropilaelaps identified in Apis mellifera, T. mercedesae has the larger geographical distribution. Phylogenetic data provide a better understanding of the links between the different introductions, but still need to be consolidated. Data source Data extracted on 14 March 2024 of the World Animal Health Information System of the World Organisation for Animal Health (WAHIS-WOAH). Scientific publications (see at the end) Informal sources (e.g. beekeeping associations’ websites, exchanges with scientists from concerned countries).   Note to readers: Few health events on Tropilaelaps spp. are reported to WOAH. Most of the data analysed in this article come from scientific publications and come from studies conducted in the framework of research projects and not from official surveillance systems. These data were collected according to different protocols and do not allow a detailed and comparable analysis of the health situation in each country. Since the European Union (EU) is currently free of Tropilaelaps spp., no data came from the EU Animal Disease Information System (ADIS).   Tropilaelaps mites are external parasites of bees, originating from Asia. They reproduce and feed in the brood on bee larvae and pupae. They cause weakening, hive desertions, colony mortality and potentially significant production losses. Since Tropilaelaps depends on bee brood for its food, its survival time on adult bees and in bee matrices (e.g. pollen, royal jelly, honey, hive frame) is short (around 3 to 6 days) (Franco and Duquesne 2024).   Four species of Tropilaelaps have been described: T. clareae, T. koenigerum, T. mercedesae and T. thaï. Originally, each species tends to be associated with a giant Asian honeybee, such as Apis dorsata, Apis laboriosa and Apis breviligula. Currently, only T. mercedesae and T. clareae reproduce on Apis mellifera brood, the honeybee of European origin. These species have adapted to this new host, in which they can reproduce and ensure their parasitic cycles (de Guzman et al. 2017).   Infestation of honey bees with Tropilaelaps spp. mites is included in the list of diseases of Apinae of the WOAH. The WOAH member states are required to provide information on their health situation via the WAHIS system.   The European Union, which is free from this exotic parasitosis, regulates this disease for bees of the genus Apis. Infestation with Tropilaelaps spp. is listed in categories D and E in the EU Regulation 2018/1882 and in accordance with the Animal Health Law (EU Regulation 2016/429). Its presence must be notified.   Evolution of the geographical distribution Description Tropilaelaps spp. mites were first identified in the 1960s in tropical and subtropical areas of Asia where their primary hosts, giant honeybees, live. Delfinado and Baker first described this mite in the Philippines in 1961 (Delfinado and Baker 1961). Since then, its observation in Asia has continued to increase. However, the precise geographical distribution of Tropilaelaps and its different species remains relatively poorly understood; only a few studies exist on the subject (Figure 1 and 2). The species T. mercedesae is the most widespread in Asia. It is present in areas with a tropical climate as well as a temperate climate (Figure 2). Tropilaelaps mercedesae has been confused with T. clareae for a long time. T. clareae is the other species infesting A. mellifera and it has only been reported in the Philippines (except the Palawan Islands) and Indonesia (de Guzman et al. 2017). The geographical range of T. clareae is therefore much smaller than the geographical range of T. mercedesae (Figure 2).   Figure 1 Geographical distribution of the two Tropilaelaps species not observed in...

  Last week, Petru Jitaru attended the European Winter Plasma Conference in Berlin, where he presented the first results about the analysis of Trace elements in fish side-streams.   This work was well received, standing out as the only research of its kind at the conference and highlighting the novelty of this topic.      

An outbreak of Foot-and-Mouth Disease has been reported in Hungary in domestic cattle. The outbreak is located in the North-west of the country in the administrative zone of Győr-Moson-Sopron. This is the second case in the EU in 2025 after the outbreak in Germany in January. Restriction zones have been set up around the outbreak and animals have been slaughtered. Following sequencing, the strain responsible for the infection was identified : O/ME-SA/PanAsia2/ANT10.
