Has it occurred to anybody that the person in question with the hygiene problem may honestly not realize that he/she HAS a problem?   I only hope that this person is not on the histonet since it was made abundantly clear where they work and who they work with. Not to mention the less than sensitive suggestions made in this format.  
     If something bothers someone about a co-worker, please be a grown-up and approach the person in a private and respectful way.  If you are too shy, have your supervisor do it.  If you are incapable of doing either, you just may have a much bigger personal problem than your odiferous co-worker.
