Googling can be wonderful.  Found the Bruce R. Eastman, Philip N. Kane,
Clive A. Edwards, Linda Trytek, Bintoro Gunadi, Andrea L. Stermer and
Jacquelyn R. Mobley report of worm tests on pathogen reduction per EPA
biosolids standards:

www.oardc.ohio-state.edu/michel/csu.pdf

And here's an excerpt from a BioCycle story on same:

> ACHIEVING REQUIRED REDUCTION <

> Analytical results showed that all of the pathogen indicators in the test
row had a greater reduction than in the control row. EPA's required three-
to fourfold reduction was achieved in all of the pathogen indicators within
144 hours. Fecal coliform, Salmonella sp. and enteric virus achieved the EPA
goal in 24 hours, 72 hours and 72 hours, respectively. The helminth ova
achieved this goal within 144 hours. <

Worms are really good.  An additional value the worms brought in these
studies was the ability to deal with 80-85% moisture conditions of the
material.  And other researchers have shown that worms can handle metal
reduction in organic wastes, too!

So how come there's still no such thing as vermicompost under USNOP?
