BERSOT, Luciano dos Santos et al. Behaviour of L. monocytogenes in sliced, vacuum-packed mortadella. Braz. J. Microbiol. [online]. 2008, vol.39, n.3, pp. 514-516. ISSN 1517-8382. http://dx.doi.org/10.1590/S1517-83822008000300020.
This study evaluated the growth of naturally occurring L. monocytogenes in sliced, vacuum-packed mortadella samples during storage at 5ºC until the expiration date. Tukey's test indicated that counts of L. monocytogenes on 0, 10, 20, 30 and 40 days of storage were significantly different (p<0.05), indicating growth during shelf life. In three trials, the mean increase was 1.72 log cycles. Vacuum packing and storage under refrigeration were not effective in controlling the growth of L. monocytogenes in sliced mortadella, indicating that good manufacturing practices and implemented HACCP programs are essential to assure safety of this product.
