Marcel H. Zwietering

Wageningen University, The Netherlands


Marcel H. Zwietering, after finishing his study in biotechnology at Wageningen University in 1987 (cum laude), started in the Food Process Engineering Group at the same university. In 1993, he received his Ph.D. degree on a thesis entitled “Modeling of the microbial quality of food” (cum laude). He continued in the same group as an Assistant and later as an Associate Professor. His research was focused mainly on quantitative microbiology and risk assessment. In 1995, he spent a sabbatical half year at the Unilever Research Lab in Colworth House, UK. In 1998, he moved to the research lab of Danone, Le Plessis Robinson in France, where he worked on quality control of starter cultures, investigation of the symbiosis, metabolic flux analysis, and quantitative risk assessment. Since January 2003, he has been a Professor of food microbiology at Wageningen University. Within this chair research, subjects in the domain of risk analysis, fermentation, detection and hygiene, ecophysiology, and functional genomics are investigated. Zwietering is a Board Member of the Food Microbiology Section of the Dutch Society of Microbiology, and a Member of the ILSI Risk Analysis in Microbiology Task Force. Furthermore, he serves on the Advisory Board of the Centre of Infectious Diseases. He is regularly invited for expert consultations like the Expert Panel for Listeria Monocytogenes in Foods (ILSI Risk Science Institute, Washington 2003), Expert FAO/WHO Workshop on E. sakazakii and other microorganisms in powdered infant formula (Geneva 2004/Rome 2006), and EFSA Working Group on Infant Formula: “Review of the opinion on microbiological risks in infant formulae and follow-on formulae with regard to enterobacteriacea as indicators” (Brussels 2006–2007). In 2005, he was elected as a Member of the International Commission on Microbiological Specifications for Foods (ICMSF), and in 2006 he was appointed at the Dutch Health Council.
