2018 Outbreak of Norovirus, Okinawa Teriyaki, Seattle, Washington

In May 2018 Public Health Seattle King County (PHSKC) staff investigated an outbreak of norovirus among patrons of Okinawa Teriyaki located at 1100 Western Avenue in Seattle. As of May 17, 2018 there were 17 ill persons from three separate meal parties. Meal dates occurred on May 8 and May 9. Environmental Health investigators visited the restaurant on May 11. The investigators observed that proper disinfectants were not being used to clean kitchen surfaces. They also learned that a customer had vomited in the dining area on May 7 or May 8 and it appears an effective cleaning solution against norovirus was not used when cleaning the vomit. If this customer was infected with norovirus, this could have contaminated the dining area with norovirus. No employees reported being ill. The restaurant is normally closed over the weekend and employees conducted a thorough cleaning and disinfection of the kitchen and dining area during this time.
