The phrasing "any known living organism" already excludes that.

Even if it didn't, a guarantee in product marketing is a promise and quasi-legal committment, not a certification of objective universal cosmic truth.

In some cases, everybody knows that statistically there will be at least one case where the guarantee is broken, but that doesn't void anything.
