Salmonella detected in food trays

On April 15, the Khanh Hoa Food Safety and Hygiene Department announced a report on food poisoning at Nguyen Van Troi High School, Nha Trang City.

According to this unit, on the night of March 30, after receiving information that students of Nguyen Van Troi High School had symptoms of suspected food poisoning and were hospitalized for treatment; the medical department of Nha Trang City Medical Center quickly grasped the information and mobilized personnel to investigate at hospitals where patients were suspected of having food poisoning.

Through verification, 12 students were hospitalized with symptoms of abdominal pain, loose stools, fever, nausea, vomiting; the hospitals diagnosed intestinal infections, acute gastritis, enteritis, digestive infections, and food poisoning caused by bacteria.

Through information exploitation, the food poisoning cases reported eating food in front of Nguyen Van Troi High School in the morning and afternoon of March 28 and 29.

The food poisoning investigation team coordinated with the People's Committee of Xuong Huan Ward and the city police force to investigate and verify that there were 3 street food establishments serving meals to students on the sidewalk at 32 Han Thuyen, Xuong Huan Ward.

At the time of investigation, the above 3 establishments no longer had samples of processed food and food ingredients, so the investigation team was only able to collect samples of the hands of food processors, samples of the surfaces of food containers, and samples of tap water used to wash utensils and food.

Through investigation, the patients all had one thing in common: they bought food from Ms. DTHO in the morning and afternoon of March 28 and 29; the food was chicken fried noodles, chicken spaghetti, chicken pasta, chicken rice, fried chicken and egg sauce.

According to the test results of the Nha Trang Pasteur Institute, for the samples taken at Ms. DTHO's facility on March 31, the surface samples of the egg sauce and fried chicken containers detected Salmonella spp and Escherichia coli bacteria.

For samples taken at Ms. PTTT's facility on March 31, samples of the surface of rice containers detected Escherichia coli bacteria.

According to the Khanh Hoa Department of Food Safety and Hygiene, because they could not collect food samples from the meal, they could only collect samples of the surface of the food containers on March 31; the sample collection time was 2 days after the food poisoning occurred, so the test results could not be used as a basis for assessing the cause of the food poisoning.

The test results of 7 clinical samples (stool samples) of food poisoning patients on March 31 found that 1/7 samples were positive for Salmonella spp. bacteria.
