Milorganite is also certified by the USDA as a bio-based product since it is derived from renewable materials. The EPA's "Exceptional Quality" criteria was changed significantly, allowing for a higher levels of toxins. Lead, for example was raised from 111 to 267 pounds per acre. Arsenic was raised from 12.5 to 36 pounds per acre. Mercury from 13.4 to 50 pounds per acre, and chromium from 472 to 2,672.[SUP]

This allowed fertilizer of this type to be more widely accepted and used.

...sadly Milorganite suffers from the same issues as anything else made from an urban sewage sludge base.
I would have some difficulties using it on food crops for this reason, although the EPA seems to have come to terms with it.
You can actually get composted cow manure that has less issues in the way of heavy metals, but it comes out of feed lots
here, which in turn have their own sets of issues. It's always somethin'.
