E.Coli - Could someone answer some simple questions, please?

Ryan-lee Young, E. coli bacteria are probably the most common bacteria in the world. It seems that they are almost everywhere. There are several types (called "strains") of E. coli. Most are harmless; some very few may be deadly. In our bodies, our normal feces ("stool") contain many millions of E. coli, most of which are helpful in the intestines. Only with a ruptured appendix are the E. coli likely to cause severe trouble. Just about all drinking water contains a few harmless E. coli and the number is constantly monitored by public health professionals. Proper sewage processing to safely handle body waste is critical worldwide to prevent spread of any deadly E. coli. Sometimes bad sewage handling allows the sewage to be used to fertilize growing crops of vegetables. This is against the laws. The present clusters of death from E. coli have been due to a new deadly strain of E. coli found in some vegetable growing areas of nortern Germany, and have spread to France this week, but not to the USA. The specific vegetables identified as responsible have been bean sprouts, but others might be yet identified. Raw vegetables must be thoroughly washed and best cooked for easy destruction of E. coli. So far, the USA and UK have been safe and will only see the new strain in some travelers who have recently returned from France and northern Germany. I still plan to continue eating salads in the USA.
