Norovirus-like illness associated with Habit Burger Grill

Highlights, updated August 10, 2021

Summary

Public Health investigated an outbreak of norovirus illness with vomiting, diarrhea, body aches, and chills associated with Habit Burger Grill in Shoreline.

We have not identified how norovirus was spread within the restaurant. This is not uncommon for norovirus outbreaks because the virus can spread through multiple contaminated food items, environmental surfaces, and from person to person.

Illnesses

Since May 24, 2021, 39 people from 15 unrelated meal parties reported becoming ill after consuming food from Habit Burger Grill from May 21-May 25, 2021. No ill employees were identified.

Public Health actions

Environmental Health investigators visited the restaurant on May 26, 2021. Investigators did not find any risk factors that are known to contribute to the spread of norovirus. The restaurant was required to conduct a thorough cleaning and disinfection. Investigators revisited the restaurant on May 28 and conducted onsite food safety and employee illness training with staff and reinforced cleaning, disinfection, handwashing, and no bare hand contact with ready to eat foods. Investigators revisited the restaurant on June 10 and ensured ongoing compliance with proper food handling practices.

Laboratory testing

One ill person tested positive for norovirus. Often in norovirus outbreaks, no laboratory testing is done because people tend to get better within a day or two. Symptoms among those who got sick and were not tested are suggestive of norovirus.
