To estimate the effects on foot-and-mouth disease virus (FMDV) of disinfectants used on Japanese farms, we investigated the effects on bovine rhinitis B virus (BRBV) and bovine adenovirus type 7 (BAdV-7), instead of FMDV, under conditions that mimicked field usage. We employed eight disinfectants : calcium hydroxide,sodium carbonate, citric acid, iodine, chlorine, aldehyde, disinfectant complex and quaternary ammonium compounds with a 0.1% sodium hydroxide. Among the disinfectants mixed with bovine excreta slurry, calcium hydroxide and sodium carbonate inactivated both viruses. After mixing them with bovine raw milk, all disinfectants could inactivate both viruses except for chlorine on BAdV-7. After sprinkling the disinfectants on soil and compost, calcium hydroxide and sodium carbonate could inactivate BRBV, and only calcium hydroxide could inactivate BAdV. These results suggested that FMDV on soil and compost might be inactivated by calcium hydroxide and sodium carbonate and that all disinfectants might inactivate FMDV in raw milk.
