La toxina Shiga Escherichia coli (en anglès:Shiga Toxine Escherichia Coli, STEC) és un bacteri responsable de les colitis hemorràgiques i de la síndrome hemolítica i urèmica.

Es tracta de la nova definició internacionali es coneix també sota altres noms com enterohemorrhagic E. coli (EHEC), Shiga-like toxin-producing E. coli (SLTEC ou STEC), hemolytic uremic syndrome–associated enterohemorrhagic E. coli (HUSEC) i verocytotoxin- o verotoxin-producing E. coli (VTEC).[1]

Shiga fa referència a Kiyoshi Shiga qui descobrí Shigella dysenteriae un dels bacteris del gènere shigella.
