This is being combated by an new version of QF, manufactured for individuals in Canada. The batch contains a vial of Uric acid that you add the the QF before you pour it in the cup.
Actually Deige, the Canadian version has been on the market for a few years now. In fact, I have a few archived posts in the forum advising Canadian users to use the Canadian batch (They can be found by doing an Advanced Search with the terms "Canadian version").

Glad to see you back Jeff. I figured your absence was because you have gotten sick of the corporate rat race and went off to some uncharted island to meditate in a cave.
