In a recent study, Sommers and others (2008)
found that FP (1.5 s steam, 121 C) inactivated 2 log of L. innocua
on the surfaces of frankfurter surfaces that contained SDA and PL,
and that growth of surviving L. innocua was inhibited during a
2-mo refrigerated storage period at 4 C. Similar results were obtained
using L. monocytogenes when frankfurters containing SDA
and PL were exposed to UVC Light, with a 3-log inactivation of
L. monocytogenes being obtained following a 2-mo refrigerated
storage period (Sommers and others 2009).
