I know that spyderco kitchen knives are dishwasher safe. The spyderco help desk taught me that.
For years people have been using knives in a variety of situations where they contact blood. They wash em and use em again. No problem. If you do the math on the risk, you're more likely to cut yourself with the knife and get an infection from dirt than you are ever likely to get a blood born pathogenic disease from blood residue on your blade.
Don't forget that a lot of hospital cleaning procedures have no place in the real world. Ironically, the biggest source of contamination in hospitals is workers refusing to properly wash their hands after and before patient care and to use gloves. This is something you too should do at home. Wash your hands before eating or touching your nose, eyes or mouth. No need to bleach clean your tools and countertops like they do in hospitals.
