Mike, I'm sure you are aware that the exact same applies to liquid compost =
extract.
Evan; I've never had any issue with molasses but then I have no tested for =
e-coli. As you have inferred, I feel the whole e-coli thing is a knee jerk =
commercial response but still something which needs addressing.
I've read the studies you mentioned done for/by the USDA as well as ones do=
ne in Canada. The flaws which jumped out at me were; 1/ no testing of proto=
zoa levels (the main e-coli consumer) 2/ the only way that they could get e=
-coli to grow was by inoculating the samples with e-coli. Duh....do you thi=
nk it might multiply??
