Disinfectants in the food industry are being replaced by a new generation of agents due to their disadvantages (corrosion, irritation, toxicity, residue problems etc.). Neutral electrolyzed water (NEW) has no negative effects on human, environmental or animal health. It does not alter food quality and is considered a more reliable disinfectant. Staphylococcus aureus causes serious health problems, especially food poisoning and intoxications. Quaternary ammonium (QA) disinfectant is commonly used for disinfection in the global food industry. We have investigated the efficacy of NEW at killing quaternary ammonium-resistant and non-resistant S. aureus strains in vitro, testing different concentrations (20 %, 50 %, 100 %) and treatment times (5, 30 and 120 min). The greatest reductions for both S. aureus strains were seen at 100 % concentrations, while no reduction was observed in the tap water used as control. Reductions of more than 6 log CFU/ml were achieved for both strains of S. aureus at 50 % and 100 % concentration. After 5 min of treatment, 6 log reductions were achieved for non-resistant S. aureus strains at 100 % concentration. QA-resistant strains declined to undetectable levels after 30 min. The results indicate that NEW may be effective in inactivating S. aureus strains in the food industry.
