Diez at FIAC
FIAC - F. Diez with hosts rescale1

CFS Director Francisco Diez participated in the Food Innovation Asia Conference 2019 in Bangkok, Thailand

Dr. Diez was one of the invited keynote speakers at the FIAC 2019 organized by the Food Science and Technology of Thailand association in June 13-14 (http://www.fiac-thailand.com/Home/Home.aspx). He delivered a couple of presentations on Current and Future Emerging Microbial Food Safety Issues and Application of Microbial Risk Assessment in Food Regulations. This conference was co-hosted by faculty from the Department of Food Technology of Khon Kaen University, one of UGA’s College of Agricultural and Environmental Sciences academic partners in Thailand. The meeting was attended by more than 200 representatives from government, industry and academic institutions in Thailand.

The 5th Edition of Food Microbiology: Fundamentals and Frontiers has been published

CFS Founding Director Mike Doyle and Francisco Diez collaborated with Prof. Colin Hill from University College Cork in Ireland as co-editors of the thoroughly updated edition of this landmark textbook. Since its introduction in 1997, the purpose of Food Microbiology: Fundamentals and Frontiers has been to serve as an advanced reference that explores the breadth and depth of food microbiology. The Fifth Edition adds coverage of the ever-expanding tool chest of new and extraordinary molecular methods to address many of the roles that microorganisms play in the production, preservation, and safety of foods.

CFS Welcomes Prof. Issmat Kassem!!!

In June, Dr. Issmat Kassem joined the Center for Food Safety as an Assistant Professor in Food Microbiology. Dr. Kassem brings to CFS a strong expertise on poultry and Campylobacter microbiology and antimicrobial resistance. He comes to CFS after serving as a faculty in Food Safety at the American University of Beirut (AUB), Lebanon. He is also an adjunct faculty of Food Safety at the Department of Veterinary Preventive Medicine (The Ohio State University). He earned a Maitrese in Biology from the Lebanese University, a Master’s in Microbiology from AUB, and a Ph.D. in Microbiology from the University of Toledo (Ohio, USA). After completing his postdoctoral studies at The Ohio State University, he was promoted to a Research Scientist. Dr. Kassem has completed certifications in food safety, preventive controls for human food, produce safety, and in advanced growers training. He was also a project coordinator and leader for capacity-building initiatives to fight foodborne diseases in Africa and the Middle East. His research interests include 1) understanding the mechanisms that contribute to the survival and transmission of foodborne bacterial pathogens in the host-environment continuum with emphasis on the food production chain, 2) evaluating factors that impact the selection and emergence of antimicrobial resistant pathogens in food production and 3) evaluating antibiotic-alternatives to control foodborne pathogens and enhance production.  His overall objective is to develop antibiotics-independent and cost-effective approaches for reducing the burden of foodborne bacterial pathogens and antimicrobial resistance on public health and the economy. He has published more than 50 peer-reviewed manuscripts and serves as an associate editor and reviewer for a number of journals in his field.
