Cereulide formation by Bacillus weihenstephanensis and mesophilic emetic Bacillus cereus at temperature abuse depends on pre-incubation conditions

Effect of chill storage on cereulide production at temperature abuse has not been investigated previously. Results of the present study indicate that storage at 5 and 8 °C will not lead to emetic intoxications, however the time at, and choice of chill temperature will determine the amount of cereulide produced in a temperature abuse situation. These results are of relevance for the safety of chilled foods of extended durability.
