Due to security considerations in their management and environmental impact is expected in the coming years the use of chlorine as a disinfectant decreases in favor of more profitable alternatives. Among these alternatives, the electrolyzed water solutions now represent the greatest advance in regard to disinfection, appearing as an efficient, ecologically and economically. The aim of this study was to compare the efficacy of electrolyzed water as a substitute for traditional disinfectant circuit milking and tank milk in a dairy farm. For this purpose water samples were collected in sterile containers at the end of the washing process with two products which were sent to a laboratory accredited by ENAC (147/LE377) for microbiological analysis. No significant differences were observed in samples treated with chlorine and electrolyzed water in the case of the circuit milking disinfection. However, in the milk tanks disinfection electrolyzed water is better than chlorine because it eliminates aerobic microorganisms. Moreover, from an environmental point of view, the use of electrolyzed water is an advantage over chlorine due to its non polluting capacity.
