The
treatment by immersion in EO water containing 50 mg/L
chlorine for 5 min significantly reduced L. monocytogenes
on tested surfaces (3.73 log/25 cm2 on stainless steel sheet,
4.24 log/25 cm2 on ceramic tile and 1.52 log/25 cm2 on
floor tile) (Liu, Duan, & Su, 2006). Huang et al. (2006a)
also reported that EO water was a very effective sanitizer
used for cleaning fish contacting surfaces in traditional grocery
stores and fish markets, so that secondary bacterial
contamination could be prevented. EO water was especially
effective in reducing the population of E. coli and
V. parahaemolyticus contamination on tilapia.
