Zone One Testing: Do You Dare?
Many experts advise never testing zone 1 surfaces for pathogens due to recall risk if such surfaces are found contaminated with a pathogen. However, such advice – ignoring your greatest risk surfaces for your greatest food safety risk – seems logically flawed. In this SafetyChain and Eurofins co-hosted webinar, Doug Marshall, Chief Science Officer at Eurofins Microbiology discusses an approach to zone 1 testing that recommends non-direct-contact surfaces simultaneously for pathogens and indicators, then building a correlation between quantitative indicator count and Salmonella or Listeria prevalence.
Dr. Marshall will share insights on how companies are employing this approach, including:
- Exploration of the various philosophical and scientific rationales for zone 1 pathogen testing
- How to justify your zone 1 pathogen testing program to inspectors, auditors, and customers
- Examples of where ignoring zone 1 pathogen testing led to a deadly outcome
