ABSTRACT
ABSTRACT: The efficacy of newly developed Slightly Acidic Electrolyzed Water (SAEW, pH 6.25-6.53) was investigated as a convenient and safe alternative sanitizer and it was compared to other sanitizers for inactivating microorganisms adhered to the facility and aerosolized in the air of the layer house. Also, the relationships between different ventilation level and concentrations of air microorganisms in the layer house were discussed. The SAEW, Potassium Persulfate Compound solution (PPC) and tap water were sprayed within the whole house. The ventilation level were divided into three degrees by opening or closing two doors (front and rear). SAEW with an Available Chlorine Concentration (ACC) of 200 mg l−1 can inhibit isolated microbes completely, the usage of SAEW (200 mg l−1) resulted in a significant (P < 0.05) reduction in microbes on the surface of trough or cages (86.0%) and in the air (50.3%). Additionally, there were significant (P < 0.05) difference between the ventilation level.
