2016 Outbreak of Bacterial Toxin Associated with a Restaurant, Washington

In 2016 Public Health Seattle King County (PHSKC) investigators learned of 3 illnesses from a single meal party associated with Yoko 3 Restaurant located in Issaquah, Washington. The group ate at the restaurant on July 5, 2016. Later that day, three people became ill with gastrointestinal symptoms including cramping and diarrhea. Symptoms and timing of illness were consistent with the diarrheal form of Bacillus cereus or Clostridium perfringens. The food source that led to these illnesses is unknown but may have been rice, which is a frequent vehicle for bacterial toxins. No one was hospitalized and no one died. PHSKC performed a field investigation at the restaurant on July 11, 2016 which resulted in temporary closure of the facility. Investigators found several problems including storage of potentially hazardous foods at unsafe temperatures, improper cooling of potentially hazardous foods, cross contamination, and inadequate handwashing. The restaurant's permit was reinstated on July 14, 2016 after attending an administration conference and passing a reinspection.
