Abstract
ABSTRACT
Cooked poultry cuts were inoculated with five-strain composite mixtures of either
Listeria monocytogenes
or
Yersinia enterocolitica
(1,000 CFU/150-g piece), packaged in 44:56 CO

-N

, and stored at 3.5, 6.5, or 10°C for up to 5 weeks. Both
L. monocytogenes
and
Y. enterocolitica
grew under all test conditions. The presence of a naturally occurring microbiota did not influence the growth of either pathogen. Addition of lactate with the shelf life extender ALTA 2341 lengthened the lag phases of
L. monocytogenes
and
Y. enterocolitica
but did not prevent their growth.
