We investigated the prevalence of bacterial contamination in uncooked sticky rice samples obtained from markets in Japan. Between June and August, 2019, a total of 25 sticky rice samples were purchased from shops in the Tokyo area. Twenty-two (88.0%) and 10 (40.0%) of 25 sticky rice samples harbored 3.06±0.54 log spc/g of standard plates counts and 2.17±0.23 log cfu/g of enterobacteriaceae bacteria counts, respectively. Three species of Enterobacteriaceae, Pantoea dispersa, P. ananati, and Kosakonia cowanii, were identified by MALDI-TOFMS-based test. Three (12.0%) of 25 sticky rice samples harbored 2.00 log cfu/g of Bacillusspecies. Bacillusspp. was not isolated after heat treatment …
