HBV can't be contracted by food. It can only be contracted via blood and body fluids. HBV is a DNA enveloped virus, can't survives the GI gastric environment. Once HBV ( via blood and body fluids) reach the liver, the virus attachs to hepatic cells ( HBV has Tropism for liver cells) and starts its replication cycles, includes: attachment or adsorption, penatration, uncoating, replication, assembly and release by budding taking some of the cell membrane of the host cell.
