Inactivation efficiency of slightly acidic electrolyzed water against microbes on facility surfaces in a disinfection channel

Slightly acidic electrolyzed water (SAEW, pH 6.0-6.5) is an ideal and environmentally-friendly disinfectant, which was used to prevent and control bacterial infections on farms.

Description
Summary:Slightly acidic electrolyzed water (SAEW, pH 6.0-6.5) is an ideal and environmentally-friendly disinfectant, which was used to prevent and control bacterial infections on farms. This work aims to investigate the inactivation effectiveness of SAEW in inactivating microbes in a disinfection channel. The bactericidal efficiency of SAEW on equipment surfaces was compared to two commercial disinfectants, Kuei A bromide solution (KAS, 5:1000 v/v) and Glutaraldehyde solution (GS, 5:1000 v/v). The disinfection effectiveness of SAEW in inactivating Salmonella enteritidis (S. enteritidis) on equipment surfaces in the disinfection channel was evaluated, and a model was developed using multiple linear regression analysis. Results indicated that SAEW was significantly (p0.05). In addition, available chlorine concentration (ACC) was an important factor than other factors, and the inactivation efficiency of Salmonella enteritidis sprayed by SAEW treatment was different between iron materials, kits and clothing surfaces (iron > kit > clothing).
