Lab, lactic acid bacteria; Lm, L. monocytogenes; ND, not detected by either direct plating.
a,bMeans with different lowercase letters within a column for each organism are significantly different (P<0.05)
A-Cmeans with different uppercase letters within a row for each organism are significantly different (P<0.05).
