Public Health Seattle and King County has completed an investigation into a small gastrointestinal illness outbreak linked to the 13 Coins restaurant in SeaTac, with officials reporting two cases and no hospitalizations or deaths.

According to Public Health, both individuals reported becoming sick after eating at the restaurant on Feb. 19, 2026. Symptoms included diarrhea and stomach pain, with illness onset occurring the same day.

Health investigators said the outbreak appears to be over and no specific food or drink item was identified as the source. However, officials said the illnesses were consistent with bacterial toxins that can form when food is left at room temperature.

Public Health interviewed the two affected individuals and conducted an on site inspection of the restaurant on March 4. Inspectors did not find any unsafe food handling practices during that visit, though officials noted that does not rule out the possibility of unsafe conditions at the time the food was prepared.

No restaurant employees were reported ill with gastrointestinal symptoms, according to Public Health.

Officials said no laboratory testing was conducted, noting that illnesses caused by bacterial toxins often resolve quickly and may not be detectable by the time patients seek medical care.

Public Health said bacteria such as Bacillus cereus and Clostridium perfringens can grow rapidly when food is kept between 41 and 135 degrees and produce toxins that can cause vomiting, diarrhea and stomach cramps within hours of consumption.

The restaurant’s current inspection rating is listed as okay, and the investigation has been closed.

Public Health encourages residents who believe they may have become ill from food prepared at a King County business to report it by calling (206) 296-4774.
