NASDA Podcast: Hazards, Risks, and Agricultural Water Sampling

NASDA 2020 Educators Roundtable Podcast: Hazards, Risks, and Agricultural Water Sampling

Dr. Don Schaffner, Extension Specialist in Food Science and Distinguished Professor.Rutgers University,

Chris and Michelle talk to Dr. Don Schaffner about risk assessment and risk management, and its use regarding agricultural water testing for the Produce Safety Rule. Don referred to a slide set that is posted (you might consider looking at it while you listen). Don starts by defining hazards and risks, and what it means for something to be “risk based”. The difference between risk assessors, risk managers, and risk communicators was also discussed, as was one of his favorite topics: indicator organisms. He then walks us through two recent papers that evaluated surface water sampling and their findings in relation to PSR requirements. This discussion includes “sampling your way to safety”, and the economics of sampling. The podcast ends with the thought that nothing in 100% safe, and encourages growers to be proactive and take the initiative on irrigation water testing.

Podcast Sessions Replacing Educators Round Table Workshop, Produce Safety Consortium March 2020   

We connect with leading scientists across the country working in diverse areas of produce safety.  In these casual discussions, our presenters share insights into the science behind some of our favorite topics in the Produce Safety Rule. These podcasts address water, cleaning, and sanitation issues beyond that expressly covered in the Rule. This series of podcasts has been developed, with help and support from NASDA, FDA, and AFDO, to explore the educational content originally scheduled for the Produce Safety Consortium Educator’s Pre-meeting workshop.
