Around 200 people were hospitalized on October 17 after consuming what may have been contaminated bread, in the central province of Quang Tri.
According to Huong Hoa General Hospital, they received patients suffering from severe abdominal pain, nausea, high fever and diarrhea.
The patients said they had eaten bread from a bakery in Khe Sanh Town in Huong Hoa District in Quang Tri Province on October 16.
The number of patients increased to around 200, and the hospital had to place 2-3 patients on a single bed and later had to add more beds along the corridor.
Some of the patients were even transferred to big hospitals as they suffered from severe food-poisoning.
Related agencies have frozen all foods in the bakery from where the above patients had bought bread, and further investigation is on to identify the cause of the food-poisoning.
