Thank you to all that quoted my reply. I did not mean that I am against the bio-solids, I totally agree that any human manure waste should be used in places/ways that is does not come in direct contact with vegetables that humans consume. I couldn't think of the words, human pathogens, that can be passed. There are several farms in this area that have gone the route and gotten the permits and all to spread it on their farmland. I don't know all the details. And yes I do realize that due to being from sewage plants, and industrial type waste, that is where the heavy metal and other contaminents come from, that wouldn't be in a "human waste compost". I just would not want to take a risk that some thing could not be composted properly and could cause someone to get sick from it, especially maybe a child....Let's face it, they have to spread it somewhere, dumping it in the ocean is not a very good option, even with the "dilution factor", although it is probably still done alot. But I think that anyone who has an ounce of common sense, would not incorporate it into their general compost heap. Most do not know how or are not able to get the composting "done right" to kill the pathogens. Yes it has been used in many counties for years, and probably still is today. But not in my vegetable garden....
