Small changes can reduce produce contamination

Cornell researchers, including the Station’s Randy Worobo and Betsy Bihn, have identified some agricultural management practices that can boost or reduce the risk of contamination in produce from two major foodborne pathogens.

For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, the biggest single killer among the foodborne microbes, report the researchers. And irrigating fields within three days and cultivating fields within a week of harvest significantly raised the risk of listeria monocytogenes contamination. However, establishing a buffer zone between fields and potential pathogen reservoirs, such as livestock operations or waterways, was found to be protective against salmonella. For more, click here.
