Campylobacter jejuni is one of the major bacteria that causes diarrhea in humans. It has been associated with many cases of food poisoning in Japan caused by eating raw or undercooked chicken meat, chicken liver, and grilled chicken (Yakitori). Campylobacter jejuni is also known as the preceding infection pathogen of Guillain–Barré syndrome (GBS), which causes considerable health impact on humans. In January 2022, in a case of C. jejuni food poisoning that occurred at a restaurant in Tokyo, one of four patients with diarrhea developed GBS. The poisoning is presumed to have been caused by undercooked chicken dishes. Recently, it was one of the common cases in Japan. Moreover, C. jejuni isolates from three patients, including the patient with GBS, had the same genotype (ST22, HS19, and LOS A). This genotype was frequently detected from patients with GBS in our past surveys. Our findings confirmed that the patient developed GBS via food poisoning after consuming undercooked chicken dish.
