Determine the Symptoms of bacillus cereus
Extremely large numbers (108 per gram) of viable cells of B. cereus must be ingested to develop signs and symptoms of the syndrome. The bacterial cells produce intoxication characterized by acute abdominal pain, flatulence and watery diarrhoea. Headache and dizziness are common, dehydration and prostration may occur but nausea, vomiting, fever and chills are rare. The illness appears within 6-15 hours after consumption of food and the symptoms usually last less than 24 hours.
