If you are in Calgary and ate at McDonald’s between Oct. 1 and Oct. 23, you may have been exposed to Hep A. A food handler at a Calgary McDonald’s was confirmed to have the infectious disease. They closed the restaurant for several hours in order to dispose of anything that may have become contaminated and to disinfect the building. The risk is low but the health department is offering free vaccinations to anyone who may have come in contact with contaminated food. Hepatitis A is a virus which attacks the liver and can be spread by food handlers if they fail to properly wash their hands after using the washroom.
