The following is the information needed and steps to take in the event that a food worker has been tested positive for COVID-19.

  1. Immediately send the sick employee home. A person who has tested positive for COVID-19, regardless of vaccination status, should remain under home isolation precautions for 5 days after symptoms begin AND at least 24 hours after fever is gone and symptoms get better, whichever is longer. If they have no symptoms or their fever is improving after 5 days, they may leave their home followed by 5 days of wearing a high-quality and well-fitting mask around others.
  2. Identify staff that may have been exposed to the COVID-19 positive worker (include up to 2 days before the worker’s symptoms began, through their last work shift). Workers who are up-to-date with vaccinations and boosters who have been exposed to someone with COVID-19 do not need to quarantine. They should wear a high-quality, well-fitting mask for 10 days after the exposure, and test in 5 days, if possible. They should watch for symptoms: cough, shortness of breath, or difficulty breathing, fever, chills, muscle pain, sore throat, or a new loss of taste or smell. This list is not all possible symptoms. Close contact usually includes being within 6 feet (2 meters) of a sick person with COVID-19 for a combined total of 15 minutes or more over the course of 24 hours.
  3. Workers who are NOT up-to-date with vaccinations should stay home for 5 days and test on day 5. It is very important to test on day 5, if possible. If you test negative on day five, you can leave your home. Continue to wear a high-quality, well-fitting mask around others for an additional 5 days.

    If it is not possible to complete a full 5-day quarantine, it is critical that you wear a high-quality, well-fitting mask around others for 10 days.

    If your close contact workers are unable to quarantine for the 5 days following exposure, Public Health asks that you include additional information in your business COVID Prevention and Control Plan. For the list of requirements for COVID Prevention Plans, see Required Information for COVID Prevention and Control Plan for Restaurants with Close Contacts.

  4. If staff have not been in close contact with the sick person, and are not sick, they are considered to be at low risk for infection. They can continue to go to work but should monitor their health for 14 days and stay away from others if they get sick.
  5. If staff have symptoms, but have not been exposed to someone with COVID-19 and have not tested positive for COVID-19, they should stay home away from others and avoid public places until 24 hours after the fever is gone and symptoms get better.
  6. If workers have symptoms of COVID-19, they should get tested. If they don’t have a doctor, call the King County COVID-19 Call Center at 206-477-3977 for assistance. If they do have a doctor, call them to get a test. Free COVID testing sites.
  7. Cleaning, sanitizing and ventilation:
    • If possible, wait 24 hours from the last time the sick employee was in the facility, before cleaning and sanitizing the area the worker spent most of their time, to minimize potential exposure for other employees.
    • During this period, open outside doors and windows to increase air circulation in these areas.

    Continue routinely cleaning and sanitizing all food preparation surfaces in the facility, and disinfect non-food preparation high touch surfaces, such as restrooms, floors, door handles, keypads, etc. Follow CDC cleaning and disinfection recommendations for non- food preparation surfaces.

  8. Reporting cases and protecting employees' privacy:
  9. Food businesses must notify Public Health within 24 hours if you suspect COVID is spreading in your workplace or if there are two or more confirmed or suspected cases among your employees in a 14-day period. At this time, food business employers are highly encouraged to report single cases of COVID-19 among employees to Public Health – Seattle & King County.

    If one of your employees has been diagnosed with COVID-19 and may have been in close contact with others while infectious, notify other employees they may have been exposed, but do not identify the person who is sick. Report COVID cases online or call the COVID-19 Call Center at 206-477-3977 (open daily, 8:00 a.m. to 7:00 p.m.).

Please review employee health policies and procedures with staff. Employee health policies should prohibit food workers from working in food establishments while sick.
