It does not take into account how much of a product a person can safely consume.
So I'm getting the sense this is about as meaningful as "Known to the state of California to possibly cause cancer".
I'm really not a fan of this extreme level of caution when it comes to public health warnings. There comes a point when people will simply stop listening to you entirely if you constantly tell them that everything they do has some 0.00001% chance of harming them. Then, when you try to warn people about genuinely concerning risks, people will simply ignore you.
