At
21 C, populations of MAB on rough rice stored at 43% RH
remained constant for 24 wk. At 68 and 85% RH, MAB populations
decreased by 0.8 and 1.1 log CFU/g, respectively, after 24 wk.
Populations of MAB on brown rice decreased by 0.8, 1.8, and
0.9 log CFU/g after 24 wk at 21 C and RHs of 43, 68, and 85%,
respectively. Populations of MAB on white rice remained constant,
regardless of RH, during storage time and are attributed mostly to
the B. cereus inoculum.
