Whole-Genome Sequencing (WGS): A Tutorial and Hands-on Workshop

Whole-Genome Sequencing (WGS): A Tutorial and Hands-on Workshop to Help Understand Its Application to Food Safety

May 6-9, 2019

Whole-Genome Sequencing (WGS) is revolutionizing our understanding of the bacterial genome and is increasingly being used to improve food safety. WGS has been used as part of foodborne outbreak investigations, both domestically and globally, to trace the source of outbreaks. Furthermore, we are just beginning to utilize the full power of improved DNA and RNA sequencing technologies to understand microbial communities and their impact on the farm-to-fork continuum to better improve the quality and safety of food and public health. However, sequencing analysis is more complex than previous methodologies and requires advanced training in molecular techniques, data analysis, and data interpretation. This workshop will provide participants an overview of the various DNA and RNA sequencing technologies and allow for a hands-on demonstration of the various data analysis options – and the science behind them. Furthermore, FDA personnel will offer sessions on data interpretation so that participants can better understand how WGS is used as part of the regulatory decision-making process for foodborne outbreaks. FDA personnel will also provide sessions on how the application of WGS on foodborne pathogens can be used as part of a preventative control strategy and will be increasingly used to make safer food. Additionally, participants will have the opportunity to help shape the content of the course by responding to the attached questionnaire to comment or request specific sessions on topics related to WGS and food safety of their choosing, allowing for a more directed learning experience.
