What is the incubation period and primary symptom of Bacillus cereus associated with foodborne intoxication?

30 minutes, vomiting
1 hour, diarrhea
1 hour, vomiting
30 minutes, diarrhea

The correct answer is: 30 minutes, vomiting

Bacillus cereus is a type of bacteria that can cause foodborne illness, particularly in relation to food intoxication. The incubation period for this type of intoxication is notably brief, typically ranging from 30 minutes to several hours after consumption of contaminated food. The primary symptom associated with Bacillus cereus foodborne intoxication is indeed vomiting, which can appear swiftly after ingestion of the toxin produced by the bacteria. In this situation, the correct answer highlights both the short incubation period of 30 minutes and the primary symptom of vomiting, which is essential for identifying the type of foodborne illness caused by Bacillus cereus. Understanding this aspect of food safety helps in preventing and responding to foodborne illnesses effectively, especially since the symptoms can present quickly after the consumption of contaminated food. This rapid response time is crucial in food safety protocols and awareness.
