This guideline sound reasonable enough,but it means that every product must be proven harmless before it can go on the market for consumers.In contrast, U.S. industries currently practice the philosophy of innocent until proven quilty.which means that a product is removed from market only after it has been proven to cause harm.This approach allows companies to put more products on the market more quickly,but it also means that they don't have to pull a product from the market until some harm has not only already occurred but also been scientifically proven.
