Validation Methods for Post-Harvest Fresh Produce Washing, Validation Methods & Alternative Interventions

The foodborne illness outbreaks have been continuously linked to fresh produce such as: bagged salads and pre-prepared fruit. Addressing the food safety issues that are linked to fresh produce requires a focus on implementing on-farm controls such as those outlined in the Final Fresh Produce Rule and CanGAP. Though prevention is considered to be the ideal control strategy, there are major challenges due to the open nature of crop production. As a result, there remains a reliance on the post-harvest interventions that primarily takes the form of biocidal washes despite limited efficacy and problems with validation.

In this session, expert speaker Dr. Keith Warriner will describe the advances in post-harvest washing of fresh produce and the US FDA’s plan to devise a method for validating the process. The session will also describe alternatives to post-harvest washing, which includes gas phase treatments, in addition to those based on advanced oxidative process. It will provide you with working examples on how using a combination of interventions can enhance the microbiological safety of fresh produce in a hurdle approach. It will also outline the future directions and research needs.
