That's interesting. Do you mean, blind tasting, and the beers tasted contaminated, or the beers were cultured in the lab to see if anything else was in there except the yeast? If the latter, I don't think it's terribly important, provided the beers tasted great. Even the yeasts we buy don't claim to have no wild yeast present, they all give a "maximium" proportion. Almost nothing is entirely free from microorganisms of one kind or another, so better we concern ourselves with the "proof of the pudding" rather than lab figures.
