Escherichia coli bacteria are normal residents of human intestines, but some strains make toxins, called Shiga toxins, that can cause diarrhea and more serious disease. The strain causing the latest European outbreak is called E. coli O104:H4, a new and particularly virulent variety of enterohemorrhagic E. coli.

The European Center for Disease Prevention and Control says that, as of June 7, the strain has sickened 2,429 people and killed 23 in the European Union, with 22 of those deaths and most illnesses reported in Germany.
