A suspected Clostridium perfringens outbreak affected 30 people in Greece in 2021, according to a study.
In May 2021, several gastroenteritis cases were reported among students and staff of a high school on a Greek island. Daily hot lunches were delivered by a catering company and consumed in classrooms.
In late May, the Hellenic National Public Health Organization was informed by a regional unit of the Hellenic Food Authority (EFET) about a cluster of gastroenteritis cases among 12 to 18-year-old students and teachers. The school is in a small town on a remote north-eastern Aegean Greek island, which had limited capacity for specific laboratory testing.
