Keeping bacteria at bay in the fishing and fish farming industries

Active bacteria on industrial surfaces can turn into viable but non-culturable cells (VBNC) under major stressors like disinfectants. VBNCs don’t grow in Petri dishes but are considered live bacteria and can contaminate food and even become active again later.
A PhD student at CEA-Leti is developing a VBNC detection method for the fishing and fish farming industries.
Combining spectroscopy and stable isotope labeling, the method has produced encouraging results on Listeria monocytogenes VBNC.
Plus, it is probably applicable to other bacteria, like Escherichia coli and Vibrio.
The research won a Best Poster Award at the 2021 French Society of Microbiology conference.
