I glossed over a lot of the detail from that class, because I wanted to
keep the email short. But to provide a few more details:
1) only mammalian or avian-based manures are a risk. Earthworm
castings are not a risk if they are dining on plant wastes.
2) There was a theory floating around for awhile that only intensively
grain-fed ruminants could produce deadly variants of E coli, which would have
been a nice reason (amongst many) to shut down feedlots. But recent
findings amongst wild elk in the Rockies indicates that grain-fed versus
not-grain-fed doesn't matter. Any warm-blooded creature (mammals or birds)
can ingest, create and pass on E coli. Grass-fed cows have also been found
to carry deadly variants of E coli. We use rabbits to build our beds here,
and like you that seemed very reasonable to me until I learned that any mammal
can produce those deadly strains.
3) While using mulch and landscape fabric would be sufficient to protect
the crops immediately above them, any contact you may have with the soil
downstream of a contamination source is sufficient to cause contamination.
Any source of water-soil interaction (muddy spots in the driveway, disturbed
soil while putting up fenceposts, etc) is sufficient to get it on your clothing
and shoes which can then spread it around to the rest of your growing
area. It can be spread much like a cold can be spread from person to
person - any form of direct contact. But irrigation was listed as the #1
way that E coli can move around on the farm, and from one farm to another,
because the water carries it along. Contaminated irrigation water is the
suspected source of contamination in several recent E coli contamination cases
which made the news.
I'm not a huge fan of these new suggestions either. I was just
wondering what changes, if any, other growers might be making with these new
research findings. I remember during the last big flood here, farmers were
told they couldn't market crops touched by the floodwaters. The
near-universal comment was "show me the research to back up your requirements
and then I'll go along with it." Well, now we've got some of those
research findings. Hence my question for what folks were going to do about
it.
