contaminant introduction via Wyeast 3763

[Spidey]

I was thinking of brewing Jamil's Flemish Sour Ale, and I was really psyched about it. But just before I'm about to order the ingredients, I'm questioning whether this is a wise decision. The recipe calls for Wyeast 3763 Roeselare Blend, a mix of yeast and bacteria. My concern is that I'll be introducing bacteria strains that like beer to my brewing equipment (and my house). Sure, bacteria are everywhere and that's why we sterilize our brewing equipment. I know how to sterilize properly (I'm a cell biologist), yet I'm a bit worried about directly introducing a source of contamination in future batches. I haven't had any contamination in the year and a half since I started brewing, and it's not something I care to fight in the future. Do you guys think that I'm being overly cautious? Should I use a different set of equipment for beers that require bacteria? Is the potential trouble of contamination not worth it?
Thanks,
Greg

You are not crazy... when doing funk beers keep seperate equipment (at least the plastic stuff, glass can be sanitized better) Might even want to transfer in a different part of the house, just to be sure.

I have plastics dedicated to the funky stuff that I store in another room away from the rest of my brewing equipment. I figure the glass carboys are okay, but I also segregate my "funky" kegs.
