Tech Talk Tuesday – Researchers Study Faster Method to Detect Listeria Monocytogenes


By Brett Dooley January 25, 2022

Norwegian scientists are examining a quicker method to detect Listeria monocytogenes

Researchers at food research institute Nofima were able to detect Listeria in four hours, which is 20 hours faster than with the traditional enrichment method. They achieved quicker detection by using MinION, a handheld sequencing device from Oxford Nanopore Technologies.

The traditional method used to detect Listeria requires taking a sample from processing equipment or food and cultivating it in a medium conducive to growth. This process can take up to several days, during which time production can continue and additional food products may become contaminated. Read more
