The E.Coli in our digestive tracts is not the
same as the one or more that can make
you dreadfully sick. You might say they
just share the first name of a long name sequence. It is not easily washed
away
and food that has it would have to be boiled for a while before the bacteria
would
be killed.
A 'massive dose' in the world of microbiology can be an amount that you
could fit on the head of a pin. Luckily,
it is not that common. Outbreaks can
be controlled if health authorities investigate and act to control the source.
In absence of that, use good judgement
and eat only food that you know has not
made others sick. (cruiser rule # 4329)
