I was wondering that also, would composting it help?
Geoff Lawton mentions composting a goat, and a human body in his and Mollisons PDC DVD's and says that the composting process will kill all pathogens. I wonder if the heat would degraded the chemicals....

I say pretty sure because there are a lot of horses (about 20) that contribute to the pile I draw from, and most are individually owned so I'm assuming that at least some of them (probably most) use chemical de-worming agents. On the plus side, I'm told that other than this, there are no synthetic treatments added, including no anti-biotics. There's probably chem traces in some of the grain feed though.
I'm guessing that my yields and plant health would have been noticeably better without the chemical in the manure but until I get the veganic methods down, I have little choice.

But since the aforementioned farmer has offered me her organic cow/sheep/pig manure, I think it prudent to make the switch.
