Considering cheeses S60 and P80a, representing a sweet and a piquant typologies, artificially contaminated with a similar
L. monocytogenes concentration, no differences in paste contamination emerged that could be attributable to the different physicochemical characteristics of the sweet and piquant typologies. Anyway, few informations are available so far to allow to discuss an eventual relation between cheese parameters (in particular the higher pH and NaCl content and the lower aw of the piquant typology) and cross contamination.
