shows the toxigenic gene
pattern type of B. cereus isolates from rice produced in eight production
regions. Regardless of the degree of milling, Type I (85.1%)
was the most prevalent. Type I isolates contained the six genes
encoding HBL and NHE, but not the ces gene, which is required for
the production of emetic toxin. Thus, these isolates have high
diarrheal toxin-producing potential, but low emetic toxinproducing
potential. Since most cases of illness caused by emetic
toxin produced by B. cereus have been reported to occur as a result
of consuming rice-based foods
