Highlights

Updated March 4, 2022
Summary

Public Health investigated an outbreak of norovirus-like illness associated with vomiting, diarrhea, abdominal pain, and chills at Rock Wood Fired Pizza in Renton.

At this time, 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 February 22, 2022, 10 people from 3 separate meal parties reported becoming ill after eating food from the Rock Wood Fired Pizza between February 19 and 20, 2022.

We have identified three ill employees who reported symptoms consistent with norovirus dating back to February 20, 2022, but who did not work while sick.

Public Health actions

Environmental Health Investigators visited the restaurant on February 23, 2022. Investigators did not find any risk factors that are known to contribute to the spread of norovirus. The restaurant closed on February 23, 2022, to complete a thorough cleaning and disinfection. All ready-to-eat foods were discarded for those processed before the restaurant was disinfected.

Environmental Health Investigators revisited the restaurant on February 24 and confirmed proper cleaning and disinfection was completed. The restaurant was reopened on February 24, 2022.

Investigators reviewed with restaurant management the requirement that ill staff are not allowed to work until they are symptom-free for at least 48 hours and provided education about preventing the spread of norovirus — including proper handwashing and preventing bare hand contact with ready-to-eat foods.

Laboratory testing

One individual who reported symptoms 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 are suggestive of norovirus.

Report possible foodborne illness

About norovirus

  • Norovirus is a highly contagious virus that frequently spreads person-to-person and is often associated with food. Norovirus illness often has a sudden onset of nausea and vomiting and/or watery diarrhea with cramps. A low-grade fever, chills, and body aches sometimes occur.
  • Norovirus rarely causes severe complications. Dehydration is the most common complication, particularly among young children and the elderly. No vaccine is available for norovirus.

Prevention

General advice for reducing risk of contracting norovirus:

  • Wash hands, cutting boards, and counters used for food preparation immediately after use to avoid cross-contamination of other foods.
  • Wash hands thoroughly with soap after using the bathroom or changing diapers, and before preparing any food or eating.
  • Wait at least 48 hours after the last episode of vomiting and/or diarrhea before preparing any food for others.
