Aims and objectives

Food and waterborne infections are where human health, animal health, and the environment intersect. In 2023, to make the world safer, the Food and Agriculture Organization of the United Nations (FAO), the United Nations Environment Programme (UNEP), the World Health Organization (WHO), and the World Organisation for Animal Health (WOAH) joined forces to prioritise One Health plans. To align with these efforts, the ESCMID Food- and Water-borne Infections Study Group (EFWISG) is committed to: 

  • Bringing together experts from around the globe in medicine, research, and public health to exchange and share knowledge on preventing food and waterborne infections
  • Facilitating networking and mentorship among professionals to spur collaborative projects, joint research, and knowledge exchange
  • Promoting the education of emerging scientists in the latest One Health advancements, enriching their understanding of critical issues such as food safety
  • Fostering a growing global community dedicated to exchanging ideas, collaborating on projects, and advancing innovative diagnostic methods such antimicrobial susceptibility testing, genomics, molecular diagnosis, metagenomics, artificial intelligence, Matrix Assisted Laser Desorption Ionization - Time of Flight Mass Spectrometry (MALDI-TOF MS), Fourier-Transform Infrared Spectroscopy (FTIR), and beyond
