Marcel Zwietering featured in Smarter Food Safety podcast

Marcel Zwietering, Professor of Food Microbiology and long-standing member of the ICMSF, has been featured in the Smarter Food Safety podcast series hosted by Frank Yiannas.

In the episode titled “False Confidence: When Food Testing Gets Sampling Wrong”, Zwietering discusses a critical issue in modern food safety management: the limitations of microbiological testing when sampling plans are not properly designed or interpreted. The conversation highlights how reliance on limited finished product testing can create a false sense of assurance, particularly when contamination is unevenly distributed or present at low levels.

The discussion reinforces key ICMSF principles that effective food safety management depends primarily on preventive control systems, risk-based approaches, and scientifically designed sampling strategies, rather than assuming that testing alone can confirm safety. Zwietering explains that absence of detection in a small number of samples does not equate to absence of hazard in a food lot, a concept widely addressed in ICMSF publications on sampling theory and risk-based microbiological criteria.

The episode forms part of the Smarter Food Safety series, hosted by former FDA Deputy Commissioner Frank Yiannas, which focuses on contemporary challenges and innovations in food safety systems.
