What government agencies think matters because they outline what's legal and what's not, and that in turn dictates what ends up in your food or not. If the government agencies are wrong, you can end up slowly being poisoned. A 250,000 times gap is the difference between one milligram and a quarter of a kilogram.
Where do you think government policy comes from? If the people who are smart and wealthy enough to torch half a million dollars on original independent research care more about who's breaking the law rather than what's true, then you have a circular dependency that breaks your system. That's why the law is so crazy and nothing crazy should be taken seriously regardless of how officially important it is.
