NASDA Podcast: Indicators, Index Organisms, and Generic E. coli

NASDA 2020 Educators Roundtable Podcast: Indicators, Index Organisms, and Generic E. coli

Dr. Faith Critzer, Associate Professor and Produce Safety Extension Specialist, Washington State University,

In this episode, Chris and Michelle talk with Dr. Faith Critzer about the confusion around the produce safety terms of indicators and index organisms. They discuss generic E. coli and what coliforms mean in water testing as opposed to environmental indicators for sanitation. Field sampling and the myth of testing your way to safety is also explored. Faith also points out some new directions research may go to fill the gaps that exist in the scientific literature.

Dr. Michelle Danyluk, Professor and Extension Specialist – Food Microbiology, University of Florida IFAS,

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.
