Mean reductions in L. innocua of 1.1, 1.4 and 1.93 log10 cfu/ml
were obtained in samples treated with PL for 2, 4 and 8 s, respectively.
In contrast to E. coli following the 8 s treatment, L. innocua
survivors could still be detected (1.95 log10 cfu/ml). No significant
differences in counts were observed when samples exposed 2 or 4 s
treatments were compared (p 0.05) while significant differences
were noticed between the 2 and 8 s treatments (p
