The practice of whole genome sequencing (WGS) has received a great deal of attention in the food industry and among industry trade associations in recent years. Whole genome sequencing is a process that uses laboratory methods to determine or map the complete DNA sequence of an organism’s genome. Each microorganism has a unique genetic fingerprint that can be identified and traced using WGS.
Disease detectives use WGS as an important tool in foodborne illness outbreaks and recall situations. It provides genetic information about the germs (microorganisms) making people sick. This information improves our ability to detect, investigate and stop future foodborne outbreaks.
