Listeria monocytogenes isolated from the smoked salmon industry: Growth potential under different environmental conditions

► Listeria monocytogenes different biotypes were apparently related to production technology. ► Sub-optimal growth conditions (salt, T) can enhance physiological strains biodiversity. ► Different behaviour of L. m. from smoked salmon can be underestimated in common media. ► Impact of strain biodiversity may be relevant under thermal abuse storage conditions. ► Knowledge of strain growth in presence of stressors is necessary to improve prediction models.
