i don't know that it's pertinent however for general info, the dairy
lab/plant I worked in didn't test for coliform nor E. coli
downstream from the pasteurizer. We tested for coliform (presumptive)
using violet red bile agar and didn't run the completed test that is
called for in standard methods. And never did test for E. coli or a
specific strain of E.coli. We did test for presumptive coliform in
individual dairy (from the farm)samples.And again did not do the
completed test.
I guess this points out not all labs run samples according to
standard methods. We also did not test our pasteurizer just the
other guy's(incoming from the farm) samples. Dennis

someone present to the NOSB a definition of and guidelines for what
you term "properly made compost." Does the scientific literature
currently support such a definition and are there commonly accepted
analytic tests that can easily be applied to compost to find out
whether it has been "properly made"? Are these tests available to the
average farmer or gardener or do they require the use of a
professional lab? Or is it just enough to follow a certain series of
steps without testing the result to insure "properly made compost?"

compost tea has three aspects that must be dealt with separately: 1)
guidelines or procedures for preparing the feeder compost "properly";
2) a test to show after preparation that the feeder compost meets the
desired standards before being used to make the tea; and 3) a test to
show that the tea, once brewed, is safe and effective. If someone
says that all this sounds too complicated to be practicable, how do
you answer the objection?

types of compost, the feeder compost and the aerobic. The concept of
what is "proper" will have to be very clear and evidence-backed. (Can
proper making of compost be quantified in the same way as, say.
proper Pasteurization has been?)
