E. coli:0157 is only pathogenic to those raised in isolation from it. When
people visiting farms stated catching it they started wondering why the farm
families didn't get it and had never had it. Seem if you are raised around
it as almost all people were 100 years ago you are immune. It is only when
you no longer have horses in the streets nor cattle near where your live
that catch the disease.

see also polio....
