Title: Re: sewage in fertilizer/mulch
The Milwaukee Metropolitan Sewage District sells such a product.

http://www.milorganite.com

In their FAQ regarding heavy metals, they state:

I heard that Milorganite contains heavy metals. Is that true?
Yes, that is true. All fertilizers, both organic and synthetic, contain some heavy metals. In fact, plants need some heavy metals, such as zinc and copper and molybdenum, for normal, healthy growth. Milorganite meets the U.S. Environmental Protection Agency (EPA) "Exceptional Quality", which establishes the strictest concentration limits in the fertilizer industry for heavy metals. Many other common fertilizer products exceed the limits for metal concentrations established by the EPA "Exceptional Quality" standards. Milorganite, though, can be used with confidence for all your fertilizing needs, including use on all types of grass, trees, shrubs, flowers and vegetable gardens.


I guess we all have to decide for ourselves.

Since it was manure I expect it had sewage in it.  Several years ago the cities were giving the sewage waste away and even bringing it to you.  Not any more, now they are mixing it with composted leaves and wood chips and selling it.  I worry about heavy metals.  And germs that are not killed by the composting.  Now I will read all the small print anyway.
