50 from Cheongju high school show food poisoning symptoms after Jeju trip; investigation launched

Health authorities in South Korea have launched an epidemiological investigation after 50 individuals, including students and teachers from a high school in Cheongju, reported symptoms of food poisoning following a school trip to Jeju Island. The outbreak has prompted concern and a thorough examination by local health centers.

The affected group, comprising 47 students and 3 teachers, fell ill starting May 23 with symptoms such as vomiting and diarrhea. They received medical treatment for their condition. The school trip, which involved 243 participants, took place from May 20 to 22 and included visits to various Jeju attractions like museums, Cheonjiyeon Falls, and the 4.3 Peace Park.

Specimens from the affected individuals have been collected and sent for testing to the Chungbuk Institute of Health and Environment. Health officials are collaborating with Jeju authorities to investigate the restaurants and other facilities the group visited. Given that symptoms were not widespread among all participants, the investigation is exploring multiple possibilities, including individual hygiene practices and potential infectious disease transmission, in addition to foodborne illness.

The Chungbuk Provincial Office of Education has stated that while the school is operating normally, students and teachers from the affected grade level are being kept separate from other grades during meals and daily activities. Emphasis is also being placed on personal hygiene management for all students and staff. The final results of the investigation are expected in four to six weeks.
