Officials with Public Health – Seattle & King County are investigating an outbreak of gastroenteritis with vomiting, nausea, and diarrhea associated with Subway restaurant located in Normandy Park.


Last week, health officials learned of eight people from two separate groups who became ill after eating food from the restaurant on October 22, 2017.

While laboratory confirmation is not available, symptoms are suggestive of norovirus. Often in norovirus outbreaks, no laboratory testing is done. The exact food item that caused the illness has not yet been identified, though this is not uncommon for norovirus outbreaks where multiple food items may be contaminated.

The restaurant management is working cooperatively with Public Health and has thoroughly cleaned and sanitized the restaurant.
