초록
The livestock infections had been happened seasonally, but they have gradually changed to be irrelevant to seasons and have an aspect to rapidly spreadafter outbreak. Especially in Korea, proactive disinfection measures are very important because the livestock farms are located densely so high as toaccelerate the spread of disease between farms. livestock disease outbreaks like HPAI and FMD occurred with high probability due to vehicles visitingthe farms, this study is to evaluate the efficiency of livestock vehicle disinfection systems by investigating the disinfectant coverage according to thetype of vehicle disinfection system and the type of vehicle quantitatively. In field experiments, water-sensitive papers (WSPs) were attached to 21locations on the surface of four vehicles (sedan, SUV, truck, and feed transport), respectively, and exposed to disinfectants while the vehicle was sprayedin two vehicle disinfection systems (tunnel type and simplified type). The WSPs were scanned and image-processed to calculate the disinfectantcoverage. The results showed that the tunnel-type vehicle disinfection system had a better disinfection performance with an average coverage of 90.27%for all vehicles compared to 32.62% of the simplified type system. The problem of the simplified system was a wide coefficient of variation (1.05-1.31)of the disinfectant coverage between 21 locations indicating a need for further improvement of nozzle location and arrangement.
