This study evaluated the activity of antimicrobials added to two
types of heat processed RTE meat products (bolognas and frankfurters),
for the control of L. monocytogenes during refrigerated
storage, simulating the occurrence of post-processing contamination.
The antimicrobials were two nisin-based growth inhibitors
(NovaGARD®LM100 and NovaGARD®NR100), the individual components
of these two products, sodium lactate (Purasal S®) and
liquid smoke (AM5®). Lactic acid bacteria and yeasts and molds
were also monitored in frankfurters, as indicators of shelf-life.
