Whole genome sequencing as a tool to strengthen foodborne disease surveillance and response: module 1: introductory module

Overview

Whole genome sequencing (WGS) is a laboratory technique that has the potential to change how we detect and monitor microbial hazards in the food chain, as well as how we assess, investigate and manage food safety risks. It is anticipated that this technology will help reduce the burden of foodborne diseases, given its advantages over previous low-resolution typing and detection methods.

The purpose of this publication is to provide guidance on the capacities that need to be in place before WGS can be successfully used for the surveillance of and response to foodborne diseases, options for implementing WGS and how to integrate WGS within existing systems. 

Module 1: Introductory module 

This introductory module explains the minimum capacity requirements in the foodborne diseases surveillance and response system prior to considering the implementation of WGS. These requirements cover the epidemiological capacity for detecting outbreaks and conducting outbreak investigations, laboratory capacities to test clinical specimens, and capacity within the food safety system in order to respond to events and undertake control measures.
