Maybe they confused it with biosolids (which are composted and then used in urban bagged compost like Cedar Grove compost.
Tested, composted Class A biosolids are also spread on many farms, with regulatory controls.
I thought the first Milorganite link was a little coy about whether "wastewater" included sewage, but the part that I thought would resolve most peoples' concerns was:
"subsequently dried in twelve rotary driers at temperatures ranging from 900⁰ - 1200⁰F. Any surviving pathogens are killed from the extreme hot temperatures."
At 900F, I would think so.
But personally, now that human biosolids from sewage treatment plants are tested for pathogens and heavy metals, I wouldn't hesitate to add them to my compost heap and then use that compost on vegetables. It's another part of "the circle of life".
