​The Committee on Food Microbiology is committed to proactively improving the understanding and control of microbial food safety hazards to enable scientifically informed decision making.

The Food Microbiology Committee achieves its mission through supporting sound science, and fostering collaboration between academia, government, and industry.

How are research priorities identified?

In advance of setting priorities for each new research cycle, the committee and its scientific advisors hold a research roundtable with representatives from federal and international agencies. These include: the US Centers for Disease Control and Prevention (CDC), the US Food and Drug Administration (FDA) Center for Food Safety and Nutrition (CFSAN) and Office of Food and Veterinary Medicine; the United States Department of Agriculture (USDA) Agricultural Research Service (ARS), Food Safety and Inspection Service (FSIS), and National Institute of Food and Agriculture (NIFA); the European Food Safety Authority and; Health Canada. The objective of these roundtable discussions is to identify emerging food microbiology research needs considered critical to public health.

Reference Strain Collection

Established in 2001 for Listeria monocytogenes isolates and housed at Cornell University, the Reference Strain Collection was expanded in 2006 to include the strain set and subtyping data that emerged from the committee’s Cronobacter (formerly Enterobacter) sakazakii projects. A 2008 expansion included the strains set of Salmonella resulting from the committee's Salmonella low-moisture projects. Isolates from the collection are available for a minimal charge to investigators around the world. This unique resource provides investigators with a standard set of isolates that improves comparison of research data. The Food Microbiology Committee continues to support the expansion of the strain collection.

Access the IAFNS collection at Cornell University.

Induction of the Viable-but-Nonculturable State in Salmonella Contaminating Dried Fruit

Salmonella is a leading foodborne pathogen globally causing numerous outbreaks of foodborne illnesses and remains the leading contributor to deaths attributed to foodborne disease in the United States and other industrialized nations. Therefore, efficient detection methods for Salmonella contaminating food are critical for public health and food safety. Culture-based microbiological methods are considered the gold standard for the detection and enumeration of Salmonella in food. Findings from this study suggest that unique stressors on dried fruit can induce the VBNC state in Salmonella, thus rendering it undetectable with culture-based methods even though the bacteria remain viable.

Evaluation of the Impact of Skewness, Clustering, and Probe Sampling Plan on Aflatoxin Detection in Corn

Probe sampling plans for aflatoxin in corn attempt to reliably estimate concentrations in bulk corn given complications like skewed contamination distribution and hotspots. To evaluate and improve sampling plans, multiple sampling strategies were assessed by Monte Carlo simulation.

Survival and Inactivation by Advanced Oxidative Process of Foodborne Viruses in Model Low-Moisture Foods

Low-moisture foods (LMFs) are generally considered as ready-to-eat products, which undergo no or minimal pathogen reduction steps. However, numerous foodborne viral outbreaks associated with LMFs have been reported in recent years. The objective of this study was to examine the survival of foodborne viruses in LMFs and to evaluate the efficacy of advanced oxidative process treatment in the inactivation of these viruses.
