Increasing MW‐specific energy from zero (control) to 900 kJ/kg‐grain resulted in statistically significant decreases in rice microbial loads. At the highest specific energy, the reduction in the aerobic bacterial and aflatoxigenic fungal loads of Aspergillus flavus was 4.56 and 2.93 log colony‐forming units, respectively; virtually no statistically significant disparity of the A. flavus mold count was observed across the entire rice bed of up to 15 cm thickness.
