Mechanistic understanding of food safety

A fundamental, physics-based understanding of the physical and biological mechanisms of pathogen attachment and infiltration of fresh produce is a critical aspect of mitigation. It will complement, not replace, the biological and experimental understanding that already exists across many studies. We simulate growth and spreading on fresh produce in order to better understand active attachment and internalization from surface contamination due to irrigation or wash water.
