Officials at the Labrador-Grenfell Regional Health Authority say there is a case of hepatitis A in their region.
The health authority says the person affected was outside the country for a time and is a worker at a Tim Hortons outlet in Labrador City.
Officials are advising residents who consumed food or beverages at the Tim Hortons between July 3 to 6, and who have symptoms of hepatitis A, to contact their family doctor.
Hepatitis A, an acute infectious disease of the liver, is caused by a virus that can be transmitted through contaminated food or drink.
Symptoms include fever, fatigue, loss of appetite, an upset stomach, diarrhea, jaundice and darkening of the urine.
