This seems an absurd concern as I don't know of many organisms that can survive an hour boil.
I don't think the OP is putting the dirt in the boil. His first post indicates he wants to ferment a beer using dirt (instead of a traditional yeast). He talks about making a starter with dirt, hoping to see if any microorganisms residing in the dirt are capable of creating a fermentation.
To your point, if the dirt were added to the boil, yes it would be less concerning to consider the danger of parasites, etc.. But it sounds like his plan is to (pitch) the dirt-starter to the wort post-boil, which to me underscores the concern over something nasty ending up in the theoretical final product.
