Abstract
Specific growth rates of two strains of Listeria monocytogenes in unir radiated and irradiated (2 kGy) roast beef and gravy stored at 5-degre es and 10-degrees-C were found to be similar. However, exponential gro wth of L. monocytogenes after irradiation was preceded by an extended lag period of 6-9 d at 5-degrees-C and 3-4 d at 10-degrees-C, compared with lag periods of 1-2 d and <0.1 d in unirradiated beef and gravy s tored similarly.
