The "indicator" test methods for foods were developed from water testing.
_E. coli_ in water was thought to be only from human sewage. The
"indication" was, if human sewage was present so was _Salmonella_,
_Shigella_, cholera, you name it. This then became the food test method
idea also. Back in 1974, when I was in Medical Technology school,
_E.coli_ was called "enterotoxigenic" or "enteropathogenic" only when it
caused illness or death in babies. Only recently has the few serotypes
(O157:H7 is one) been found to cause death in adults. Now these are called
"Hemorrhagic" _E. coli and look for "VTEC" used on this news group.
Only a few serotypes are deadly (so far). Still, I don't think I want to
eat viable _E.coli_ knowing the sources are human sewage and in the case
on hamburgers, cow intestinal content (manure).
