Effectiveness of alkaline electrolyzed water in reducing bacterial load on surfaces intended to come into contact with food.
Alkaline electrolyzed water (REW) is known for its cleaning action. The aim of this work was to assess REW effectiveness in reducing microbial load on surfaces intended for contact with food. Stainlesssteel surfaces were experimentally contaminated, bacterial inactivation was tested before and after treatment with REW. Treatment with REW was operated spraying it on the contaminated plates until drying. Tests were conducted for Salmonella spp., Listeria spp., Staphylococcus aureus and Escherichia coli. The treatment revealed different degrees of sanitizing activity of REW on different bacterial species, with higher efficacy on E. coli and Salmonella spp. than S. aureus, Listeria spp.. Statistical analysis revealed a significant microbial load reduction (p<0.01) after treatment with REW, suggesting that it has a good disinfectant activity which, along with its easy and safe use, makes it a good alternative to many other more widely used disinfectants.
期刊介绍：
The Journal of Food Safety (IJFS) is the official journal of the Italian Association of Veterinary Food Hygienists (AIVI). The Journal addresses veterinary food hygienists, specialists in the food industry and experts offering technical support and advice on food of animal origin. The Journal of Food Safety publishes original research papers concerning food safety and hygiene, animal health, zoonoses and food safety, food safety economics. Reviews, editorials, technical reports, brief notes, conference proceedings, letters to the Editor, book reviews are also welcome. Every article published in the Journal will be peer-reviewed by experts in the field and selected by members of the editorial board. The publication of manuscripts is subject to the approval of the Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.
