The way flubenol works is a by interfering with the recepters of invertebrates, it is not toxic, therefore it stops the parasite from being able to utilise certain nutrients thereby starving them to death.
Have you emailed the owner of the site to ask for more info? as I would have thought that would have been your best start rather than deliberatly trying to find faults in the product just because you can't beleive its not toxic to fish
