title: Growth Potential ofListeria Monocytogenesin Sliced TurkeyBresaolaPacked in Modified Atmosphere.
abstract: According to EC Regulation No 2073/2005, for food business operators that produce ready-to-eat (RTE) product, it is crucial to be able to demonstrate if the product supports the growth ofListeria monocytogenes. The objective of the study was therefore to evaluate the behaviour ofL. monocytogenesin sliced RTE turkeybresaola(made by cured turkey breast 4.5% NaCl, 1% sodium lactate, sodium nitrite 150 ppm and flavouring) during the shelf life of the product, simulating a contamination during the slicing operation. Considering a shelf life of 90 days, as defined by manufacturer, the packages of slicedbresaolawere stored at 5°C for 7 days and at 8°C for the remaining storage time (83 days).L. monocytogenescount decreased during storage test from 1.43/1.98 log cfu/g in the three batches tested to 1.03 log cfu/g in one batch and to undetectable levels in the other two batches. The results show that the investigated product is unable to support the growth ofL. monocytogenes.
