A. Each
of the following treatment processes are acceptable for a biological soil
amendment of animal origin that the farm applies in the growing of covered
produce, provided that the resulting biological soil amendments are applied in
accordance with the applicable requirements of Section R3-10-806:
1. A scientifically valid controlled physical
process, chemical process, biological process, or a combination of
scientifically valid controlled physical, chemical, or biological processes
that has been validated to satisfy the microbial standard in subsection (B),
for Listeria monocytogenes (L. monocytogenes), Salmonella
species, and E. coli O157:H7; or
2. A scientifically valid controlled
physical, chemical, or biological process, or a combination of scientifically
valid controlled physical, chemical, or biological processes, that has been
validated to satisfy the microbial standard in subsection (C), for
salmonella species and fecal coliforms. Examples of
scientifically valid controlled biological processes that meet the microbial
standard in subsection (C), include both:
a.
Static composting that maintains aerobic conditions at a minimum of 131° F
(55° C) for three consecutive days and is followed by adequate curing;
and
b. Turned composting that
maintains aerobic conditions at a minimum of 131°F (55° C) for 15 days,
which do not have to be consecutive, with a minimum of five turnings, and is
followed by adequate curing.
B. The following microbial standards for
L. monocytogenes, Salmonella species, and
E.
coli O157:H7 apply to the treatment processes in subsection (A):
|
For the microorganism
|
The microbial standard is
|
|
1. L. monocytogenes
|
Not detected using a method that can detect one
colony forming unit (CFU) per 5 grams (or milliliter, if liquid is being
sampled) analytical portion.
|
|
2. Salmonella species
|
Not detected using a method that can detect three
most probable numbers (MPN) per 4 grams (or milliliter, if liquid is being
sampled) of total solids.
|
|
3. E. coli O157:H7
|
Not detected using a method that can detect 0.3 MPN
per 1 gram (or milliliter, if liquid is being sampled) analytical
portion.
|
C.
Salmonella species are not detected using a method that can
detect three MPN Salmonella species per 4 grams (or
milliliter, if liquid is being sampled) of total solids, and less than 1,000
MPN fecal coliforms per gram (or milliliter, if liquid is being sampled) of
total solids.
