Behaviour of L. monocytogenes in sliced, vacuum-packed mortadella Comportamento de L. monocytogenes em mortadelas fatiadas e embaladas a vácuo

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<...
