If you've recently contracted E. coli, it's probably because you've been eating raw cookie dough again. E. coli, better known by its full name Escherichia coli has been found in Nestle Toll House cookie dough. How can something so pure be so evil? That's just the nature of life; then again you didn't think you could bite into this and not end up with bloody diarrhea did you?
Reminds me of something my mother used to say. "If it looks like a turd and contains Gram negative bacterium commonly found in fecal matter, it's probably a turd."
