•Commercial Bt Strains as a Putative Cause of Food Poisoning

•Food Poisoning by the Emetic Toxin of B. cereus

•Food Poisoning by Enterotoxins of B. cereus

•Other Enterotoxins of B. cereus

•Enterotoxins of B. thuringiensis

 

 

Commercial strains of Bt used in pest and vector control, such as Btk and Bti, are all sibling species of B. cereus.

1. cereus was shown to be a relatively minor cause of food poisoning events in humans

The close relationship of these two species raised concerns that Bt, rather than B. cereus, may be the cause of some occasional outbreaks of food poisoning in humans.

Food poisoning caused by B. cereus is due to two types of toxins :

•emetic toxins, which cause vomiting

•enterotoxins, which cause gastrointestinal dis- comfort that often leads to diarrhea.
