So... Odd question time. I was wondering if human bloodborne diseases would be able to withstand the processes of cooking and drying required to make blood sausage. I tried to find an answer for Hepatitis specifically, but I couldn't find a clear answer. I don't believe the cooking temperatures would get high enough to destroy these viruses, but the drying should get them right? Before you ask, this isn't for any established world, I was just idly worldbuilding a group of faux-vampires. I think I could spin this into a one-off short story.
