Thermal Inactivation and Growth Potential of Listeria Monocytogenes in Smoked Tench
An experimental study for the evaluation of Listeria monocytogenes inactivation during a hot smoking process in tench was performed using Listeria innocua strains. Furthermore, the survival of L. monocytogenes in smoked tench was determined after post-processing in contaminated samples, evaluating the growth potential during storage. L innocua was not detected after the smoking process. In the ...
متن کاملListeria monocytogenes growth rates on cold-smoked salmon and evaluation
19 Salting and smoking are ancient processes for fish preservation. The effects of salt and phenolic 20 smoke compounds on the growth rate of L. monocytogenes in cold-smoked salmon were 21 investigated, through physico-chemical analyses, challenge tests on surface of cold-smoked 22 salmon at 4°C and 8°C, and a survey of the literature. Estimated growth rates were compared to 23 predictions of e...
متن کاملExpanded models for the non-thermal inactivation of Listeria monocytogenes.
Previously developed four-variable response surface models for describing the effects of temperature, pH/lactic acid, sodium chloride and sodium nitrite on the time to achieve a 4-log, non-thermal inactivation (t4D) of Listeria monocytogenes in aerobic, acidic environments were expanded to five-variable models that distinguish the effects of pH and acidulant concentration. A total of 18 new var...
متن کاملModeling the growth characteristics of Listeria monocytogenes and native microflora in smoked salmon.
Smoked salmon contaminated with Listeria monocytogenes has been implicated in foodborne listeriosis. The objectives of this study were to model the growth characteristics and examine the growth relationship of L. monocytogenes and native microflora in smoked salmon. Smoked salmon samples with a native microflora count of 2.9 log(10) CFU/g were inoculated with a 6-strain mixture of L. monocytoge...
متن کاملCharacterization and pathogenic potential of Listeria monocytogenes isolates from the smoked fish industry.
This study was designed to evaluate the hypothesis that some of the Listeria monocytogenes subtypes associated with foods, specifically smoked fish, may have an attenuated ability to cause human disease. We tested this hypothesis by using two different approaches: (i) comparison of molecular subtypes found among 117 isolates from smoked fish, raw materials, fish in process, and processing envir...
