This article in New Food Magazine discusses how Next Generation Sequencing (NGS) and Whole Gene Sequencing (WGS) can assist in detecting and identifying contamination, and also playing an important role in assuring traceability of food products when combined with blockchain along the supply chain. Technology improvements have meant that NGS and WGS have high throughputs at much lower cost than before, and NGS machine can now be used for WGS as well.

The genomic information derived by these techniques on pathogenic bacterial contamination when combined with data such as the date and place of findings, can help track down the exact sources of contamination and therefore avoid large scale recalls of food products. The role of NGS in obtaining DNA traceability combined with blockchain permits products all the way along the supply chain to be traced back to their original raw materials whether that be plants or animals.
