In hospitals and certain commercial facilities, it is very important that dishes be properly washed. I agree with the industry that, for that very reason, the best product is phosphorus. This is not as important an issue where household use is concerned, because there is no risk that the general population will be contaminated. If I were drafting a bill, I would exclude hospitals and possibly some commercial institutions.
