We've had this before here. Dead bodies don't harbour pathogens. Disease-causing organisms require living tissue and/or body temperature. After death, decay organisms quickly take over. A smell issue rather than a health issue. I did point to a website, funerals.org I think, that clarifies this. I mean, how do you think embalmers, funeral directors and cremation attendants would get on if they were constantly having to handle "diseased corpses?" The answer is, they don't. The organisms lose their virulence shortly after death. I believe that HIV could be a rare exception to that. When this came up before, someone mentioned anthrax spores. Well I don't think we need go around worrying about that too much. If you're going to get anthrax it probably won't be from your dead granny.
