Bacillus cereus is a Gram-positive, anaerobic, spore-forming, toxin-producing bacillus. It is commonly found in the environment, usually in soil and vegetation, but it is also present in food.

Bacillus cereus is a saprophytic bacterium, currently considered a leading cause of food poisoning, second only to Salmonella (typhoid bacteria) and viruses. Bacillus cereus causes two different clinical manifestations: vomiting syndrome and diarrhea syndrome.

Previously, as reported, many cases showed signs of food poisoning after eating Phuong bread on September 11. The first person showed signs of poisoning at 11am the same day. The time from eating to the appearance of symptoms was at least 2 hours, and at most 16 hours.

According to health authorities, nearly 150 people were hospitalized for food poisoning after eating Phuong bread. Most of them have been discharged from the hospital, and there have been no serious cases. Currently, authorities have requested that Phuong bread temporarily cease operations.
