> "Which specific pathogens are we testing for when animal manure is
used in compost per recommendations? All those of major,minor and
intermediate concern in animal manure???????? It's one thing to test
for coliforms(somewhat of a generic test) however all those
organisms,etc would take forever to test for and cost a fortune.
We test for some of that stuff in food( items of concern) however not
all in any one product,afaik. I've worked in probably 10 different
corp. food labs and never seen such extensive testing on food let
alone soil amendments. Testing for E. coli and enterococci may be
quick and dirty(like when presumptive test is neg or nf or whatever
terminology is nowadays for negative however when id or confirmation
is required test takes lots longer. 
     There goes more time in the lab away from farming cause I don't
think it'll EVER come up negative. You can test 'til after the cows
come home!And then sell the cows to pay for testing and sample
shipment.

      So much for using ACT on certified organic crops  for human
consumption without pre harvest restrictions.
    When compost is used directly on crops for human consumption what
testing is required of it? With animal manure and w/o animal manure
used in that compost's prod.?
     I can see the elimination of ACT's use on edible sprout prod.
