- To establish appropriate conditions for a disinfectant efficacy test at subzero temperatures, this study examined mixtures of frozen foot-and-mouth disease virus or avian influenza virus solutions and disinfectant diluents at ?5oC and monitored temperature and freezing status of an anti-freezing diluent (AFD, 15% ethanol + 30% propylene glycol + 55% distilled water) over time at various subzero temperatures. Viral solutions and disinfectant diluents froze before the mixtures reached ?5oC, whereas the AFD was not frozen at ?30oC. The times taken for the AFD to reach ?10, ?20, ?30, and ?40oC from room temperature were 36, 39, 45, and 48 min, respectively. ? 2019 Korean Society of Veterinary Science. All rights reserved.
