Step-by-step explanation:
The common symptoms of Bacillus cereus gastroenteritis are 1) nausea and vomiting, 2) abdominal cramps, and 3) watery diarrhea. Thus, the correct answer to the student's query is 4) All of the above. B. cereus is a bacterium frequently found in soil and is known to cause foodborne illness. After ingestion, it can produce toxins leading to symptoms that typically appear within a few hours. Bacillus cereus is particularly dangerous because it can form spores that survive cooking and can grow and produce toxins in food if it is not stored properly.
Infections can range from mild to severe, impacting individuals differently. Some individuals may undergo complications beyond the gastrointestinal discomfort, potentially including long-term health issues or even life-threatening conditions. However, mild cases usually resolve without extensive intervention.
