In the kindergarten in Sangnok-gu, Ansan-si, Gyeonggi Province, it has been 8th and 26th since a group food poisoning incident, including hemolytic uremic syndrome (HUS, aka Hamburger's disease), remains unconfirmed.

Ansan-si Sangnoksu Public Health Center, which is investigating the path of food poisoning, has taken more than 30 cases of preservation meals for raw foods of the kindergarten and 100 environmental samples collected from cooking knives, cutting boards, and door hooks along with the Korea Centers for Disease Control, Food and Drug Safety, and Gyeonggi-do. I checked it.

We also inspected all the officials and related food companies that supplied food for this kindergarten, and especially for beef, we traced the history to the production and livestock farms to complete the inspection.

Recently, after checking the learning process of the native students, they also investigated the soil used in the'treasure hunting in the earth' program and the water washed by the natives.

However, no food poisoning bacteria were detected anywhere.

The suspicion of the six preservation diets that disappeared without finding the causative organism is getting worse, but since it has already disappeared, investigation of the infection route is practically impossible.

The police are investigating the possibility of deliberate disposal of the preservation ceremony, but it has been reported that the investigation based on CCTV video footage has yet to find any apparent suspicion.

An official from the Evergreens Public Health Center said, "Since it is impossible to realistically investigate the path of infection through the six missing preservation formulas, we will look at the investigations so far and at the same time, plan to conduct a close reexamination against unstorable preservative food ingredients suppliers." .

Meanwhile, the city of Ansan extended the temporary closing order period of the kindergarten that had been held until this day until the 17th to further investigate the path of infection.

On the 12th of last month, in connection with the group food poisoning accident of the first patient on the 12th, by the afternoon of the 7th, 118 cases of food poisoning (e.g., 113 native students, 5 native families) occurred, of which 65 were positive for gut hemorrhagic E. coli. received.

36 were hospitalized, 30 were discharged, 6 were still hospitalized, and 1 out of 16 patients diagnosed with hemolytic uremic syndrome, an intestinal hemorrhagic E. coli complication, were still being treated for dialysis.
