This is not a risk for HIV. HIV does not infect outside a living host. It does not live on intimate objects. You have zero concerns for HIV from touching a bag.
Post your hepatitis in the hepatitis forum for answers on that because this one only deals with HIV assessment.
Dont worry, No HIV tests are needed, for the hepatitis .. The virus can survive for 3 weeks outside the body, If I were you I wont be worried, take anti-HCV and anti-HBV after 12 weeks
