Several weeks ago I got a call from a producer of CSI to get background on an episode that they were thinking of running.  I just finished watching the episode (click on photo below).  Frankly, most of the science was inaccurate, but the point that E. coli O157:H7 is a poison and that producers whose food is tainted could be held criminally liable should worry some of my readers.  Yes, E. coli O157:H7 is murder.
