Much is still unknown about contamination risks from pathogens in fruit packing warehouses. Researchers across the country are working to learn more about the survivability of specific pathogens on different surfaces and how warehouses can improve processes to address the problem. Case in point: No one really knows how easily Listeria monocytogenes, a highly deadly soilborne pathogen, survives on fresh apples in storage and whether die off changes by type of storage — refrigerated atmosphere, controlled atmosphere (CA), or CA with ozone. Ozone, in particular, raises interesting questions, because it already has been shown to reduce microbes on surfaces in […]
