Free food microbiology on-demand webinar

We would like to invite the food microbiology testing laboratories community to view our webinar and discussions on the detection of Vibrio species and uncovers validation components in validating a testing method.

Who should view this webinar:
QC Manager | QC Assistant | Lab Manager | Lab Technician | Microbiologist | QC Manager | Head of Microbiology and the broader community of food microbiology testing

During this webinar our experts will cover:

The subtle art in validating Vibrio routine methods for Vibrio testing 

Speaker: Maria Nelson, AOAC Consultant 

AOAC microbiological method validation is traditionally based on method comparison. Candidate method performance is compared to standard reference method procedures, such as those found in the US FDA Bacteriological Analytical Manual, USDA-FSIS Microbiology Laboratory Guidebook, and the International Organization for Standardization. Study designs can be qualitative and/or quantitative, depending on the candidate method result. But what do we do when the candidate method and reference method have different intentions and end results? This presentation will discuss the protocol developed to validate a multi-plex PCR method designed specifically to detect Vibrio cholerae, V. parahaemolyticus and V. vulnificus that will satisfy regulatory requirements worldwide, and the challenges faced when relying on cultural methods to evaluate PCR method performance.

An introduction to the Thermo ScientificTM SureTectTM Vibrio Cholerae, V. vulnificus and V. parahaemolyticus PCR Assay method

Speaker: Daniele Sohier, PhD, Senior Manager - Gloabl Scientific Affairs, Food Protection- Thermo Fisher

Vibrio species form part of the natural flora of the worldwide coastal marine environmental and have been isolated from a variety of different seafoods, including oysters, which are routinely eaten raw by the public and carry the risk of causing gastroenteritis in consumers. To reduce the risk of infection, a reliable and rapid detection method is required for this perishable food group.
