Treatment of fresh fruits and vegetables with Electrolyzed Water (EW) has been shown to kill or reduce foodborne pathogens. We evaluated the efficacy of EW in killing Escherichia coli O157:H7 on iceberg lettuce, cabbage, lemons, and tomatoes by using washing and/or chilling treatments simulating those followed in some food service kitchens. Greatest reduction levels on lettuce were achieved by sequentially washing with AEW (Acidic Electrolyzed Water) for 15 or 30 s followed by chilling in EAW for 15 min. This procedure reduced the pathogen by 2.8 and 3.0 log CFU per leaf, respectively, whereas washing and chilling with tap water reduced the pathogen by 1.9 and 2.4 log CFU per leaf. Washing cabbage leaves for 15 or 30 s with tap water or EAW reduced the pathogen by 2.0 and 3.0 log CFU per leaf and 2.5 to 3.0 log CFU per leaf, respectively. The pathogen was reduced by 4.7 log CFU per lemon by washing with EAW and 4.1 and 4.5 log CFU per lemon by washing with tap water for 15 or 30 s. A reduction of 5.3 log CFU per lemon was achieved by washing with AW (alkaline Water) for 15 s prior to washing with AEW for 15 s. Washing tomatoes with tap water or AEW for 15 s reduced the pathogen by 6.4 and 7.9 log CFU per tomato, respectively.
Application of AEW using procedures mimicking food service operations should help minimize cross-contamination and reduce the risk of E. coli O157:H7 being present on produce at the time of consumption

I comment each time I especially enjoy a post on a website or I have something to add to
the discussion. It is triggered by the sincerness displayed in
the article I looked at. And on this article Reduction of Escherichia
coli O157:H7 on Produce by Use of Electrolyzed Water under
Simulated Food Service Operation Conditions | Electrolyzed Water.
I was moved enough to post a commenta response 😉 I actually do have some questions for you if you
do not mind. Is it simply me or do some of the remarks come across like coming from brain dead folks?
😛 And, if you are writing on other online social sites, I’d like to follow anything new you have to post. Would you make a list all of all your social pages like your Facebook page, twitter feed, or linkedin profile?
