hepatitis A can be transmitted through food but not hep C. hep a is not nearly as serious as hep C.
I absolutely agree with Hector AND there are no documented cases of transmission through blood on food even if there are cuts in the mouth. that is why HCV patients are allowed to work in the food industry.
The hepatitis C virus is spread by blood-to-blood contact. So the blood of one person has to mix with the blood of another. This is why HCV is commonly spread by injection drug use and previously by blood transfusion, blood products, or organ transplantation prior to 1992, when blood screening for HCV first became available.
You would have to have open wounds in your mouth for the virus to pass from the other persons blood into your blood stream. So you have nothing to worry about.
