That's the point - dropped apples. There have been several oubreaks
of hemorrhagic enterocolitis and HUS due to E.coli O157/H7, traced
back to unpasteurized apple cider made from or including dropped
apples that were picked up and pressed without being washed/brushed
to remove surface contaminants.
I was fairly certain that in at least one of those(I was thinking it
was a CT outbreak, back in the early '90s), they isolated O157/H7
from some deer fecal pellets they collected in the orchard - but I
can't find documentation in a quick Google search.
But, subsequent to those outbreaks, CDC has issued guidelines
recommending that cider processors wash & brush dropped fruits, and
some additional work has been done incorporating sodium benzoate into
the wash/rinse water, as well.
Contaminated, damaged apples can support the growth of E.coli
O157/H7, and fruit flies can carry it from contaminated wounds to
