Yes, the "clock" starts the moment the poo hits the ground, so to speak.  If you have animals on the ground, these new guidelines say 210 days between the last possible poop date and the first possible harvest date. 
 
The issues for growers in flood plains is perhaps the most difficult under these new guidelines because even if they don't own animals per se, any grounds touched by flood waters which could reasonably have "touched" manure areas upstream, including rotational pasture grazing systems, would be subject to the same 210 withdrawal times.  That very topic is causing quite a bit of uproar here in western WA because most of our ag valleys flood regularly during November, and that 210 day separation would put the first harvest unacceptably late into the growing season.  Some counties like mine have a dike system such that floodwaters don't touch the growing fields (most years).  But just one county south of us opted for a no-dike flood management approach several decades ago, and those farms flood at least partially almost every year.  Many of them have precious little high ground, and that high ground is where they put their animals during flood events.  This new guideline puts most of those folks in a real bad jam.  They either blow off the guidelines, build their own dikes (which I believe is illegal even if it was affordable which it isn't), or change their entire farming schedule.  Or quit farming.  I haven't had the courage yet to ask those folks what they're going to do, particularly if this becomes a written or de-facto law.  That's some of our area's most fertile soil and these new regs would put a lot of those folks out of the veggie business.

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)?

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.

I have  always been led to believe that proper composting, with the high
temperatures  involved, will eliminate virtually all pathogens ( then , just

bury the stuff,  so it is not on the surface, just to be  sure...).
