Food Microbiology: The Past and the New Challenges

Dear colleagues,

Food production and distribution systems are becoming more interdependent, integrated, and globalized. At the same time, escalating and heavily publicized outbreaks of foodborne diseases continue to occur, and have raised awareness on the urgent need to ensure food quality and safety. Hence, active biosurveillance, from the farm to the fork, is fundamental.

Moreover, investigators and stakeholders in food microbiology need to keep updated on novel methodologies and data analysis systems, to be able to overcome past and new challenges.

In this context, and keeping in mind the One Health concept, this webinar gathers experts in food microbiology, aiming to encourage a broad and productive discussion. Hope to welcome a variety of interesting ideas and themes, to further enrich the conversation.

Date: 4 November 2022

Time: 3:30 pm CET | 10:30 am EDT | 10:30 pm CST Asia

My previous and current scientific activities have been mainly developed in the interface between Food and Clinical Microbiology. In July 2009 I assumed a Ciencia2008 position at Faculty of Veterinarian Medicine (FMV) and established my own Microbiology research lab, working with bacteria found in food and assessing for their pathogenicity potential, by comparison with human and veterinarian clinical isolates.Regarding microbial pathogenesis, the majority of the studies being performed worldwide are centered on clinical isolates. The innovative nature of my research is its main subject “food isolates” and how the so-called safe strains became pathogenic, if given the right conditions. Bacteria, although considered among the most simple living organisms, are in fact rather complex. In order to characterize and understand the underlying pathogenicity mechanisms that enable the switch between safety and pathogenicity and integrative approach directed towards gene and protein expression. Using OMICs platforms is the best way to achieve a wider image of the organism under study. Following this idea I aim to use whole-transcriptome and differential proteome profiling to study pathogenicity. The natural evolution of scientific knowledge led me to the optimization of metagenomic analysis to the microbial characterization of Portuguese Traditional cheeses with Protected Designation of Origin. Over the years the establishment of several national and international collaborations with distinct institutions enriched my scientific and personal accomplishments that I intend to maintain and expand.

National Food Institute, Research Group of Epidemiology and Foodborne Pathogens, Technical University of Denmark, Kongens Lyngby, Denmark

I am a doctor of veterinary medicine by education, and I have worked since 2010 as an epidemiologist in the field of food safety. In 2013, I completed my PhD on the subject of interpretation of quantitative microbial data for risk assessment, with a special focus on variability and uncertainty in the predictions of foodborne disease. Since 2014, my work is mainly focused on the occurrence of antimicrobial resistance in animals and the transmission of resistance to humans. My main tasks involve the implementation and evaluation of new methods for the application of genomics data in source-attribution, risk assessment and surveillance. I enjoy teaching and have had the opportunity to lecture quantitative microbial risk assessment in several international courses under the scope of the European Commission’s programs EDES and BTSF, as well as for Master and PhD students in DTU’s QMRA summer school. I also coordinated and implemented a successful Massive Open Online Course on the use of metagenomics for surveillance of pathogens and antimicrobial resistance ( I have been seconded to three different international research institutions: Austrian Agency for Health and Food Safety (2009), Tasmanian Institute of Agriculture - Food Safety Centre - University of Tasmania (2012) and Complutense University of Madrid – Department of Animal Health (2015).
