History
E. coli O104:H21 was discovered in 1982, when it caused an outbreak of severe bloody diarrhea. It had infected hamburgers, and those affected had eaten these hamburgers not fully cooked.
An outbreak of E. coli responsible for at least 22 deaths in Northern Europe in May 2011 was reported to be caused by another O104 strain, Escherichia coli O104:H4.
