According to testing conducted by the Pasteur Institute in Nha Trang, located in the south-central province of Khanh Hoa, Salmonella spp was found in seven stool samples and four food samples, while Bacillus cereus was present in four food samples taken from the shop.

Salmonella spp is a dangerous intestinal bacteria often found in improperly prepared foods such as meat, eggs, and dairy. Infections typically cause fever, abdominal pain, diarrhea, vomiting, and dehydration within hours to days.

Bacillus cereus, commonly found in starchy foods and poorly stored meat, can produce toxins that trigger vomiting, abdominal pain, and acute diarrhea.

The findings provide evidence for the ongoing investigation and will guide authorities in handling the case and issuing food safety warnings.

Between April 29 and May 1, Huong Hoa General Hospital admitted 64 patients with suspected food poisoning after they ate banh mi from a shop in Tan Lap Commune.

Most of the victims were students.

Following the incident, authorities inspected the bakery, collected food samples and ordered the shop to temporarily suspend operations from April 30 until further notice.
