The bacteria grow to dangerous numbers and produce a toxin when these foods are: cooled too slowly not stored in a fridge. Further cooking or reheating doesn't destroy the toxin. How to avoid exposure Don't leave cooked or prepared rice and other starchy food to cool slowly at room temperature.

Make sure the cooked product is either: eaten immediately kept hot at above 60 degrees Celsius cooled and stored in the fridge until used.

Advice for rice Don't cook and cool rice in large quantities — separate into smaller amounts so that it will cool quickly. If rice has been cooked for sushi or fried rice, cool it in the fridge until it is ready to use. Sushi rice usually contains sushi vinegar and a mixture of sugar and salt, which helps prevent the growth of Bacillus cereus bacteria. Note that Bacillus cereus spores survive in both dried raw rice and cooked rice.

Cooked meats are commonly prepared and sold for direct consumption in different nations. In this study, B. Research has shown that open-air stalls increases the opportunity for environmental pollution Ng et al. This could explain the high prevalence of B. Vomiting was first associated with B. Vomiting due to B. Although cold vegetable dishes in sauce RTEs undergo processing steps, they are usually not subjected to heat processing; thus, microorganisms cannot be completely eliminated on the fresh vegetables.

Some studies have indicated that the growth, harvest, processing, and packaging of vegetables are likely to increase the possibility of microbial contamination Sagoo et al. Since B. Taken together, these results suggest that the consumption of cold vegetable dishes in sauce made from vegetables contaminated with B.

Some studies have indicated that RTE foods can become contaminated by different bacterial pathogens via food preparation surfaces Christison et al. Many pathogenic bacteria such as B. These properties increase spore retention and make their removal from preparation surfaces on production lines difficult. Following its preparation, the load of B. Consequently, regulations have been imposed on the number of B.

The most common enterotoxin-encoding genes in the B. CytK is a cytotoxin isolated from a B. Hence, the widespread distribution of diarrhea-causing B. According to previous studies, starch-containing foods promote toxin production by B.

Interestingly, in this study the 18 B. Since vomiting intoxication cases have been known to cause death Mahler et al. Beyond food poisoning, B.

Antibiotic susceptibility testing can provide a reference for the clinical treatment of food poisoning. In this study, we exhaustively tested the antimicrobial resistance of all B. More than This result is unsurprising, since B. According to the results of our antimicrobial sensitivity testing, suspected B. We also found that many B. Epidemiological typing methods, such as MLST, are considered crucial for studying the prevalence of foodborne bacteria.

MLST is a nucleotide sequence-based approach for the unambiguous characterization of isolates that has been broadly used for epidemiological typing and risk analyses of many pathogenic bacteria, such as S.

Xu et al. Moreover, 28 strains were assigned to ST26, including 18 strains that were found to contain the cesB gene. In this study, we evaluated the prevalence of B. Our results indicated that RTE foods are highly contaminated with B. In addition, most of the strains exhibited MDR profiles with important implications for clinical treatment.

Together with the diverse genotypic polymorphisms we observed, our findings reveal the potential high risk of B. QW and YD supervised the project. SY and YD analyzed the data and wrote the manuscript. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Agata, N.
