    The author discussed on the concentration of airborne dust and airborne common (viable) bacteria in dairy barns in the previous paper. The present paper is concerned with the same purpose, but on the environment of the rice drying and processing facilities.
    It was considered that the concentration of airborne microbes would be proportional to the 2/3th power of the concentration of airborne dust. As a result of measured data, it was proved near correlation between these concentration value.
    The number of the microbes which attached to respirable dust was estimated as 4.5 x 10⁴ - 4.5 x 10⁶ CFP/mg.
