In January 2017 Public Health Seattle King County (PHSKC) investigated a cluster of norovirus-like illness associated with consuming raw oysters. On January 4, 2017 four people in the same meal party consumed raw oysters at Taylor Shellfish located at 124 Republican Street in Seattle. Two males and two females became ill 20-29 hours later with nausea, vomiting, diarrhea, abdominal cramps, headache and body aches. As part of the public health investigation, PHSKC Environmental Health inspectors conducted an on-site visit to the restaurant. The investigation of the restaurant did not identify any issues that would increase risk for norovirus.
