US: Researchers tap GIS to help predict on-farm foodborne pathogen risks
US Center for Produce Safety: Growers may soon be able to log onto a website, note their farm’s location and view the relative risks from foodborne pathogens as different color gradients on a map. They could then make more informed planting and management decisions that would help minimize potential contamination. That scenario isn’t too far off and is one of the next steps in research that melds geographic information system (GIS) mapping with mathematical equations to create foodborne pathogen risk-prediction models.
“People want guidelines in terms of high risk areas and how far to stay away in terms of planting,” Wiedmann said. “How many meters is that magic cutoff? Risk is never yes or no. It’s a gradient.”
