Sorry to say, but this theory has been disproven. Pasture-raised
animals and ruminant wildlife, even with no grain whatsoever, have been
positively ID'ed as being sources of dangerous strains of E coli. We
were hoping this theory would pan out in practice as yet another way to
boost grass-fed production, but it didn't. Not to say that every cow,
goat, sheep, deer or elk is a source of dangerous E coli. But merely using
no-grain methods is not a guarantee against it.

I don't
know if this helps with this conversation, but if you obtain manure from a
grass based diet fed farm, there won't be issues of E. Coli. Animals
that are fed strictly a grass based diet, even with supplimentation of
grain for the purpose of growth or making milk, will not have the
concentrations of E. Coli that are being discussed. Animals raised
in Feed Lots where they are fed mainly Corn Silage and heavy amounts of
grain with little or no hay or fresh pasture to eat will most always have
E. Coli present in their manure. We have a dairy farm, our cows receive
a total grass diet all 4 seasons of the year with a supplimentation of
grain and we spread manure on our gardens in the fall...it sits all winter
long and that is all the fertilizer we use. E. Coli can only live in a
certain amount of acidity and that is what a heavy Corn/Grain based diet
produces..lots of acidic conditions that the E. Coli thrive on. I have
not read all of the emails attached to this conversation so if I am off
base and what I have said does not pertain to this conversation than
please forgive me for jumping in. This information is also a big
plus for any who raise grass fed Beef Cows for meat
sales. Kathy Vermont ----- Original Message ----- From: "mamica5"

Just to clarify a
little, are we talking 210 days for E. Coli after it leaves the digestive
tract of mammals? I do not knowingly use manure less than a year old.
However, our bottomland vegetable production is in a flood plain subject to
winter and early spring flooding. It seems that you are suggesting that
growing there might not be safe.
Nevertheless..it is amazing that he
human race is still around considering all the varmints wandering through
our vegetable patches.

S, then, composting gets rid of the ecoli, which is
perhaps a better proces to use anyway( ups soil
microbes)? Michael

Just to be clear, we're not talking about compost.
We're talking about direct manure application to the land, and/or rotating
animals on/off of crop growing grounds, and/or having irrigation water
moving from livestock areas to growing areas. Compost treatment protocols
have NOT changed. Kathryn Kerby Frog Chorus Farm Snohomish,
