A 23-year-old graduate student died after participating in a steamed bun eating competition at Dayeh University in Changhua.

The Taipei Times reports the student could not stop vomiting and fell unconscious after he began to feel uncomfortable during the school’s eating competition on Wednesday to determine who could finish two steamed buns stuffed with egg and cheese in the fastest time.

School medical personnel immediately performed CPR on the student and an ambulance was called which rushed him to a nearby hospital, but the student was pronounced dead. The cause of death remains unclear, but doctors said that the student may have choked to death
