To examine the effect of UVC and FP on the proliferation of L. innocua
during long-termrefrigerated storage, an 8-wk storage study
(8 ◦C) was performed using untreated frankfurters that contained
SDA/PL, those treated with 1 J/cm2 : 1.5 s and 2 J/cm2 : 3 s UVCand
FP. On the untreated frankfurters, growth of L. innocua was inhibited
for approximately 2 wk at 10 ◦C, but the population rose to>107
CFU/g by the end of the storage period (Figure 1)
