R3-10-805. Biological Soil Amendment of Animal Origin; Acceptable Treatment Processes; Microbial Standards

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 microbial standards for L. monocytogenes, Salmonella species, and E. coli O157:H7 in Table 1 apply to the treatment processes in subsection (A): 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 Table 1. 1,000 MPN fecal coliforms per gram (or milliliter, if liquid is being sampled) of total solids.
