While this stuff is somewhat interesting I really have no fear of catching anything from my fish tank besides MTS. I have never worried about sticking my hands in the tank and dont think I will.
If you look at the links wilder provided, there were 18 cases reported in 20 years!
KOD-your link didnt state any additional info or reported number of cases.
If I had AIDS or was 95 years old or for whatever reason had a weakened immuned system, then I might think twice. Until then I'll eat a cheeseburger while redecorating the tank.
