News headlines often paint E. coli as a vicious bacterium, capable of causing disease and death to those unfortunate enough to ingest it. But that is only a tiny minority of E. coli, and a very small part of the story of this remarkable bacterium; its relationship to human health and the food we eat is much more complex. Not all E. coli are bad - in fact most are not - and some are even beneficial. On September 1st 2011, the American Academy of Microbiology convened an expert panel of microbiologists, food safety experts, and bacteriologists to develop a more accurate picture of this often maligned bacterium. This report, the product of that meeting, tells the larger story of E. coli: its role in human health, in food, and even in our understanding of our own biology.
