Experimental Study of Disinfection to Foot-and-Mouth Disease Virus by Pure Ozone Gas

Abstract

Disinfection against foot-and-mouth disease virus (FMDV) and swine vesicular disease virus (SVDV) placed in two kinds of animal experimental rooms by pure ozonegas were examined. The disinfecting effect of ozone gas was influenced by the quantities of viral materials, but a clear disinfectant effect against two viruseswas observed over 4mg/l of ozone concentration. FMDV was completely eliminated by ozone gas but a small amount of SVDV remained after disinfection. From these results, ozone gas could be used for disinfection against FMDV. Ozone gas was considered for use for vapor disinfection instead of formalin vapor disinfection.
